Eddie Howe has made three changes to his Newcastle United side for the Champions League game against Benfica.
Lewis Miley, Jacob Ramsey and Jacob Murphy come into the starting line-up in place of Sandro Tonali, Joelinton and Anthony Elanga following the weekend defeat against Brighton.
Tonali was a doubt for this game with illness and only makes the bench.
Newcastle starting XI: Pope, Trippier, Thiaw, Botman, Burn, Guimaraes, Miley, Ramsey Murphy, Woltemade, Gordon
Subs: Thompson, Ramsdale, Schar, Joelinton, Tonali, Barnes, Krafth, Osula, Elanga, Willock, A.Murphy
Benfica manager Jose Mourinho has also made three changes
As expected, goalkeeper Anatoliy Trubin, captain Nicolas Otamendi and midfielder Richard Rios all come back into the starting line-up after being rested for the win against Chaves in the Portuguese Cup last week.
Benfica starting XI: Trubin, Dedic, Silva, Otamendi, Araujo, Rios, Barrenchea, Aursnes, Sudakov, Lukebakio, Pavlidis

Image source, Getty ImagesNewcastle United have not won a Premier League game away from home since April. That seems like a long time, doesn't it? Yes, in a lot of ways. No, in others. What a conclusive thesis this is!
This weekend exposed more of our issues, but also showed flickers of light. Some embers from which Newcastle can once again rise. I told you once I was an irritating optimist and surprise! I have not changed.
Broadly speaking I cannot ignore our poor away form, and the uninspiring start to our season so far, and the fact that we are approximately one injury away from panic mode.
But, today, I want to hone in on the good news. And the good news is that Nick Woltemade and Lewis Miley play for us. I have watched many iterations of Newcastle United and I know how daft it is to just rely on one player being very good, and hope for flashes of brilliance, but in the absence of any creativity elsewhere on the pitch, watching Woltemade backheel the ball straight into the goal on Saturday was an extremely welcome reprieve.
It is not just one player though, don't worry. You can add in Miley, who came on after half time at the weekend to offer a bit more pace and press to our midfield.
Miley is an academy product who has been nurtured by the club carefully, and you can see what he might be able to offer us in the next few years. Not a single misplaced pass, and a technical ability on the ball that we did not have before, meant that he was able to provide the assist that brought us level (albeit only for a short time).
There are problems that need to be solved by Eddie Howe - and soon - but I think these two might be a massive part of the answer.

Image source, Getty ImagesIt was 8.25pm by the time Jose Mourinho finished up on Monday evening.
The Benfica manager had just spent the best part of half an hour answering questions in both Portuguese and English ahead of tonight's Champions League game against Newcastle United.
Yet Mourinho looked like he could have talked for another while longer in the media suite at St James' Park.
It is hard to think of an opposition manager who has such an affection for another club without ever taking charge of them.
But that was the profound impact mentor Sir Bobby Robson left on his former assistant during their time together at Sporting Lisbon, Porto and Barcelona.
"There wasn't a single day he didn't show his passion for Newcastle, for the city, for the region, for the football club," Mourinho said. "I have never hidden how dear Newcastle is to me because of the influence of a legendary person at this club."
Mourinho, a two-time winner of the competition, could not have been more complimentary about Newcastle.
He predicted Newcastle are "closer to bigger things". He spoke about how "happy" he was after opposite number Eddie Howe ended the club's 70-year wait for a major domestic trophy last season. He even revealed he told his players that the atmosphere at St James' was "beautiful".
And the 62-year-old was not finished yet.
After making his way past the bust of Sir Bobby, in the players' entrance, Mourinho even signed autographs and posed for photographs with fans who had gathered outside.
But it goes without saying that Mourinho won't be quite so friendly when the game kicks off.
Having only ever won three games at St James', the Benfica manager will be desperate to get a rare result at "Mr Robson's home".
"We have to be ready to suffer on the pitch," he said.

Image source, Getty Images"Frustrating".
That was the word Eddie Howe used to sum up Newcastle United's start to the season on Monday.
Newcastle suffered a 2-1 defeat against Brighton at the weekend to leave Howe's side in 13th place in the Premier League. And there is no time for a hangover as they quickly return to Champions League action against Benfica.
"We feel like we need another game," Howe said before the game at St James' Park on Tuesday night.
Danny Welbeck's 84th-minute winner for Albion on Saturday drew parallels with another late sucker punch Newcastle suffered, against Arsenal last month.
Their response to that setback was emphatic, just a few days later recording their biggest Champions League win by beating Union Saint-Gilloise 4-0 away from home.
Undoubtedly, Benfica will offer a sterner test.
Though the Portuguese giants have lost both of their opening European fixtures - against Qarabag and Chelsea - they were drawn from pot two for a reason after reaching the last 16 of the competition in three of the past four seasons.
They also have a two-time Champions League winner in manager Jose Mourinho, who will be desperate to prove he can still make an impact at this level.
It feels like an acid test of Newcastle's own European ambitions with goalkeeper Nick Pope hoping to take another small step towards qualifying for the knockout stages.
"It is something this football club has not done in a long time so that's a big ambition for the group," he said. "We have a top team and a top manager, and top teams get into the latter stages of the Champions League.
"Everyone wants to be a part of that."

Image source, PA MediaNewcastle United boss Eddie Howe has been speaking to the media before Tuesday's Champions League game against Benfica at St. James' Park (kick-off 20:00 BST).
Here are the key lines from his news conference:
There are no fresh injury concerns for Newcastle - however Sandro Tonali is "touch and go" as he battles illness.
Howe said his players "need this game" following their defeat by Brighton on the weekend and thinks his team is not "far away from being something more."
On whether Newcastle are in a transitional period after a busy transfer window: "Whenever you bring players in and lose players, in a sense it brings the word transition, but hopefully we've got the balance right. [By] not losing our identity and how we play. I don't think we have because you can see what we're trying to do."
He continued: "The effort's there, commitment is there but sometimes we haven't played with enough quality. As long as we see heart, endeavour and attitude, we'll get consistent results again. There is a sense of finding a new way of doing things."
Summer addition Anthony Elanga is still yet to score or assist for Newcastle but Howe has full belief in the winger: "Anthony is an outstanding player. There's a settling in period that he's going through and he's having to make slight adjustments. He's got a lot more to give and will in the future so I've got no doubts about his success here."
He conceded the Magpies are "desperate" for a win on Tuesday: "We love these games. The atmosphere will be electric and I hope their performance mirrors that energy. If we're at our very best, we have a good chance and we know the importance of home games.
Opposite number Jose Mourinho has had a "big impact" on Howe, who described the former Chelsea and Tottenham boss as a "visionary" who helped shape his own coaching philosophy.
He added: "It will be a competitive game between two great clubs. [Mourinho] has a way of inspiring his team to get results. We know what to expect and it will be up to us to influence our players and deliver the game plan that we want. They have an attacking threat and tactically, it will be an interesting game."
Image source, PA MediaNewcastle goalkeeper Nick Pope has not ruled out making England's 2026 World Cup squad, despite missing out on every one of Thomas Tuchel's selections so far.
The 33-year-old thinks it is best for his goalkeeping to do the talking as he keeps England hopes in the back of his mind.
"I spoke to him [Tuchel] when he took over or soon after, and I've been in regular contact with [goalkeeping coach Henrique] Hilario," Pope explained. "I feel like the communication has been really good.
"I'm in the frame if you like, and it's something that's not dead so it's nice to have in the back of your mind.
"I've been to two [World Cups] already so I think a third in America would be pretty special. At my age, you know there's not many more opportunities to come so, to get to the World Cup would be a good achievement for myself."
Pope has only conceded seven goals in the Premier League so far this season, including keeping five clean sheets.
Asked whether he pitches his own case to Tuchel, he replied: "Please pick me? No, it's best to let your football do the talking and keep the ball out of the net. I think that's always going to stand you in the best stead.
"Hopefully Dan Burn puts in a good word as well!
"But Newcastle at the minute comes first. Without Newcastle, there's no talk of England."

Image source, Getty ImagesNewcastle's defeat at Brighton left them with just two wins from eight matches in the Premier League this season.
The Magpies have conceded a miserly seven goals but crucially have only scored seven themselves (compared to 17 for Manchester City, 16 for Chelsea and 15 for Arsenal).
German signing Nick Woltemade has scored four of those seven and got his first goal away from St James' Park on Saturday with a cheeky backheel finish. He had not really looked a huge goal threat before then, and the same was true of the away game at Bournemouth a few weeks ago that I also worked at. He often came quite deep and looked a bit isolated.
On paper, the likes of Anthony Gordon, Anthony Elanga, Bruno Guimaraes, Harvey Barnes and Jacob Murphy should be creating lots of chances for Woltemade (and getting on the scoresheet regularly themselves) but it is just not happening in the league yet for some reason.
The protracted loss of Alexander Isak was obviously a big blow and Newcastle fans will be expecting much from £55m man Yoane Wissa, but there is still a number of weeks to wait for his first appearance.
Wissa has suffered a posterior cruciate ligament injury rather than the notorious anterior cruciate ligament issue many first feared. He is back training on grass, but his return will not be rushed for fear of aggravating the injury, so we will not see him in black and white until mid-November, I suspect.
We asked for your thoughts after Saturday's Premier League game between Brighton and Newcastle.
Here are some of your comments:
Brighton fans
Tony: It was a scrappy game but we defended well and fought hard for a well-deserved win. With a bit more finesse and better decision-making we could have won by more.
Richard: It was the best performance of the season - a really hard-fought win. We seemed to want the second ball more than recent games and those fine margins made the difference.
Hayling: Some fans have criticised Lewis Dunk this season, but he was immense - at least three superb tackles when he was left as the last man and he handled Nick Woltemede better than Jan Paul van Hecke. Just a shame we couldn't keep the clean sheet against a side who hadn't scored away from home before Saturday.
Newcastle fans
Sean: Fed up of poor performances at Brighton - the same every season. Toothless once again in attack. Anthony Elanga just hasn't got going. Showed much more attacking intent with Jacob Murphy's directness in the second half. Defensive solidity seems to be the base for us this season, yet both goals were poor to concede. Need a good reaction at St James' Park on Tuesday before a kinder run of league fixtures.
Paul: A really poor performance. Misplaced passes, losing multiple 50/50s. All across the park we didn't seem ourselves and, despite a lot of effort, we just were way below the levels needed.
John: Whatever the reason, the performance seemed adversely affected by the international break. Bruno Guimaraes missed a couple of good chances to score. Joelinton was lethargic and made mistakes so Eddie Howe removed him at half-time. Anthony Gordon had none of his England sparkle and Elanga hardly contributed. Woltemade was the exception, but when three or four other key players are off form, the Premier League is a very tough league.

Image source, Getty ImagesWhat is it about this place?
Newcastle have not won at the Amex since 2017, when both sides were in the Championship, and the manner of this defeat will certainly hurt.
Having rediscovered some momentum before the international break, following back-to-back wins against Nottingham Forest and Union Saint-Gilloise, Eddie Howe opted to name an unchanged side for the third game in a row.
But it was rather telling that the Newcastle head coach made a double change at the break as he hauled off the leggy Joelinton and the misfiring Anthony Elanga and threw on Lewis Miley and Jacob Murphy.
However, having managed to find a way back into the game through Nick Woltemade's brilliance, Newcastle conspired to lose it.
Howe's side have now failed to win any of their opening four away league games this season, scoring just once.
With trips to West Ham, Brentford and Everton to come next month, that record has to improve. Sooner rather than later.
Eddie Howe spoke to BBC Match of the Day after Newcastle's defeat against Brighton: "We are disappointed with the first half performance really. We faded and the last half hour was hard to watch. Brighton scored in that period. We were pleased to get in at 1-0 and regroup.
On his midfield: "They are brilliant players but they didn't function well today but I don't think the team did.
"When we conceded the second goal, we were the dominant team. We responded really well in the second half. They didn't have many attacks in that spell but they did go and score.
On Nick Woltemade: "There is a level of expectation there because we're signing a very good player. There's a lot to take on with a new league and a new lifestyle but he's taken that on very well."
Goalscorer Woltemade spoke to PLP after Saturday's defeat: "It's not good. First half, we didn't do good. The second half was good energy in the game. We scored one goal and it felt like we would win but they played good and scored. That's football sometimes. The second half was way better than the first.
"I really like to play here. I get balls; the players are looking for me. The gaffer trusts me.
"In the second half, we had good chances but we lost them in the first half. We didn't have good energy. It's part of football when the ball doesn't want to go in, but it's important we keep working on that.
"Before the national break, we had a good week and today you can see that we can get the game on our side in away games. We will keep working and win games away."

I was impressed by Newcastle when I watched them against Nottingham Forest. Their midfield is so powerful, and they have got good options out wide.
I don't think they will start firing properly up front until Yoane Wissa is fit to help Nick Woltemade but, defensively, they look pretty solid and that has been backed up by their results on the road.
Newcastle have drawn all three of their away games in the league this season, without scoring or conceding.
The goals will come, but I don't see them as having enough to beat a Brighton team who always look dangerous even when they are not playing that well.
The Seagulls have drawn two out of three at home so far, so I guess this has got a draw written all over it too.
Sutton's prediction: 1-1
Tom McCoy
BBC Sport journalist
Comeback kings Brighton take on a Newcastle side with more Premier League clean sheets than anyone else this season. BBC Sport examines some of the key themes before Saturday's match.
Jan Paul van Hecke's late equaliser salvaged a point for Brighton away at Wolves in their last game, maintaining the Seagulls' formidable record of coming from behind under Fabian Hurzeler.
Since the German's appointment in June 2024, Albion have gained 30 points from losing positions, at least four more than any other Premier League side.
Hurzeler called the display at Molineux "a good performance but not a great performance", adding "we can play better football but are not machines".
There is certainly room for improvement at the back. Brighton are one of only three teams still awaiting a first Premier League clean sheet of the season and have shut out the opposition just once in their past 19 top-flight games.
They do have an excellent record at home to Newcastle, having avoided defeat in all eight of their Premier League home matches against the Magpies. However, given the visitors' strong defensive record, Albion will be keen to avoid playing catch-up again this weekend.
Miserly Magpies a tough nut to crack
The international break arguably came at the wrong time for Newcastle, who registered back-to-back wins for the first time this season by beating Union Saint-Gilloise and Nottingham Forest, scoring a total of six unanswered goals in those victories.
Goalscoring has been an issue for the Magpies, with only Forest and Wolves netting fewer so far in the Premier League. However, summer signing Nick Woltemade has made a strong start to life on Tyneside, scoring in each of the past three games, easing concerns about the impact of losing Alexander Isak to Liverpool.
Woltemade, 23, maintained that momentum by scoring his first senior international goal in Germany's win against Northern Ireland on Monday.
At the other end of the pitch, Newcastle have proved a tough nut to crack, keeping five clean sheets in seven Premier League matches. That is the joint-highest total in the top five European leagues, matching Lyon's total in Ligue 1.
It is all the more impressive given Eddie Howe has had to contend with several injuries to his rearguard. Tino Livramento and Lewis Hall are not expected back until next month at the earliest, while Fabian Schar also missed time before returning as an unused substitute against Forest.
