Pep Guardiola complained that his players were "a little bit sloppy" but the Manchester City manager was delighted to rubberstamp a Champions League quarter-final place.

The Spaniard saw his side duke out a goalless draw with Sporting CP, sealing a 5-0 aggregate win after the thrashing in Lisbon three weeks ago.

City probed for a goal to satisfy the packed house at the Etihad Stadium, but they could not make a breakthrough, Gabriel Jesus having a strike disallowed for offside after a VAR check and a late flurry coming to nothing.

Given City's huge lead from the first leg, there was always a likelihood this would end in anti-climax, but the hosts at least avoided an uncomfortable night.

Guardiola said: "The first half was better than the second one. 

"I think after the disallowed goal, we were a little bit not active, didn't make movements and it's not easy because after this result the second half I think it was already over.

"We waited for counter-attacks and it was a little bit not good. But I understand it, that games in these situations it is difficult to handle it.

"The first half was much better, we were more aggressive and created chances.

"We should have played the second half like we played the last four or five minutes. We didn't do it; that's why it was a little bit sloppy, the second half."

City have now reached the last eight of the Champions League in each of the past five seasons, the only English side to do so each time over this period.

Guardiola gave Champions League debuts to three players: starter CJ Egan-Riley and substitutes James McAtee and Luke Mbete.

Egan-Riley did well at right-back, with Guardiola saying of the 19-year-old academy product: "CJ played like he is. He's not exceptional in anything, but he doesn't make mistakes and so always as a defender that's so important."

A highlight of the night for City supporters was a late cameo for veteran third-choice goalkeeper Scott Carson, as the 36-year-old replaced Ederson for the closing 17 minutes.

Carson, rarely given a look-in at first-team level, had to make one big save to keep City on terms, boosting his cult hero status at the club.

It was his second appearance in the Champions League, 16 years and 338 days after his debut for Liverpool against Juventus in April 2005 when he was 19 years old. This made it the largest gap between appearances in the competition's history.

"We are delighted. Scott is very important for us always behind the scenes," Guardiola said of the former England international.

"His chemistry with Ederson and Zack [Steffen] is fundamental in the locker room. People listen to him a lot when he talks. For a game like this it was so important and he made the biggest save so we didnt lose the game."

Guardiola played down the prospect of possibly facing a rival Premier League club in the quarter-finals, saying: "We'll prepare well and next Friday we're going to see the draw and we are going to prepare.

"It's an honour to be there. Important teams are already out so we'll see next week what happens."

Pep Guardiola picked homegrown talent CJ Egan-Riley for Manchester City's second leg with Sporting CP, handing the 19-year-old a Champions League debut.

The youngster made his maiden first-team appearance in the 6-1 Carabao Cup win over Wycombe in September, but this was comfortably the biggest senior occasion of his fledgling career at the club.

He came in amid a defensive crisis for City, with Nathan Ake, Ruben Dias, Joao Cancelo and Kyle Walker all unavailable. Ukrainian Oleksandr Zinchenko started at left-back, with John Stones and Aymeric Laporte in the centre.

It was a night at the Etihad Stadium when City were surely on their way through to the quarter-finals after seizing a commanding 5-0 lead in Lisbon three weeks ago.

Guardiola made six changes, with Egan-Riley joined by Zinchenko, Fernandinho, Ilkay Gundogan, Gabriel Jesus and Raheem Sterling, who came into the side three days after the thumping 4-1 derby win over Manchester United.

Kevin De Bruyne, Jack Grealish, Rodri and Riyad Mahrez dropped to the bench as Guardiola allowed that star quartet a breather, while Cancelo was unwell and Walker suspended.

Egan-Riley stepped in at right-back for England international Walker, who Guardiola ticked off in his pre-match news conference for the red card he received late on in City's group-stage clash with RB Leipzig after lashing out at Andre Silva.

Guardiola said: "When one player does this stupid thing he deserves the three games, I'm sorry. I'm not so kind to Kyle in this kind of action."

Pep Guardiola has full confidence in Oleksandr Zinchenko's readiness to feature for Manchester City against Sporting CP.

Zinchenko has played just once for City since his homeland of Ukraine was invaded by Russia, an attack that began on February 24.

That appearance came against Peterborough United in the FA Cup, with Zinchenko captaining City in a 2-0 win.

However, the 25-year-old seems set to start again as City host Sporting in the second leg of their Champions League last-16 tie.

City hold a 5-0 lead from the first leg in Lisbon, but Guardiola claimed he only has three defenders fit for Wednesday's meeting at the Etihad Stadium.

Kyle Walker is suspended and Joao Cancelo, who has been playing at left-back, is unwell. Nathan Ake has still not recovered from injury while Ruben Dias is expected to miss a month due to a hamstring problem.

As such, Zinchenko is likely to feature, but Guardiola insists the full-back is in the right frame of mind to feature.

"He's ready, of course it's not an easy period for him but he will be ready if he has to play," Guardiola told a news conference.

Prior to Guardiola's appearance in front of the media, City goalkeeper Ederson explained the support Zinchenko has from his team-mates.

"It's a very difficult moment for him. It's his country. His family are there, living in these anguishing moments," Ederson told reporters.

"For us who don't live there it is difficult. Can you imagine what it is like for him? It is hard to see your team-mate suffer and the civilians suffering in the country.

"We try to give him strength and bring some joy into his day but we know how difficult that is. I hope it resolves and the country can get back to normality.

"It will be very difficult due to the damage being done, the amount of innocent people that are dying due to a war that is nothing to do with them."

Pep Guardiola is still "so angry" with Kyle Walker over the full-back's three-match Champions League suspension.

Walker was sent off for lashing out at Andre Silva in the 82nd minute of City's 2-1 defeat to RB Leipzig in the group stage, with the Premier League champions having already secured qualification into the last 16.

City appealed against the England international's suspension, but it was upheld, with Walker missing the last-16 tie against Sporting CP and the first leg of the quarter-finals, with Guardiola's side surely heading for the last eight after winning the first leg 5-0.

The Premier League leaders are short of options in defence for the second leg at the Etihad Stadium on Wednesday. Ruben Dias is set to miss the next month due to a hamstring problem while Nathan Ake is not yet ready to return from injury, and Joao Cancelo is unwell.

John Stones and Aymeric Laporte are Guardiola's senior options at centre-back, while Oleksandr Zinchenko would seem the most viable option at left-back.

Guardiola said he does not know who will fill in at right-back, as he vented his frustration at Walker.

"He deserved it. Kyle Walker deserved the three," Guardiola said during a news conference when asked about City's failure to win their appeal.

"When one player does this stupid thing he deserves the three games, I'm sorry. I'm not so kind to Kyle in this kind of action.

"I'm still so angry with him, so angry. He knows it. It's not necessary to discuss that [with him].

"He's so important, Kyle for us. Did you see the game he played against United? But in Leipzig, we've qualified already, 75, 80 minutes to make this kind of action? So he deserves the three games.

"The club appealed, I did not agree. They had to do it because in other cases that were quite similar it was just two games but he deserved it. Hopefully he learns for the future."

One academy option who could be called upon is Luke Mbete, with the 18-year-old defender set to be included in City's squad.

"He's trained with us for a long time, the application is so high, a guy who wants to learn," Guardiola said.

"Still young but tomorrow he'll be with the squad and maybe we will need him, we will see."

Fernandinho, however, was namechecked as a possible option to slot into the defence, either at right-back or centre-back.

There has been talk of Fernandinho moving into a coaching role, yet Guardiola still wants to keep the Brazilian in his squad if possible.

"I would love [to offer him a new contract]," Guardiola said. 

"I'm so glad to have him he's an incredible captain and player. I have a feeling now at 36, 37, he struggled a little bit coming back from holidays but now he's getting his rhythm.

"For him he doesn't care, he will play against Peterborough. Other players his age wouldn't want to play there in cold weather, but he wants to help to give rest to Rodri. At the end of the season Txiki [Begiristain, City's director of football] and the club have to decide."

Kevin De Bruyne, meanwhile, is risking a suspension should he play and Guardiola may omit the midfielder.

"He's maybe not [going to start]," Guardiola said with a laugh. "We will see."

Ederson is full of confidence that Manchester City can go on to win a domestic and European treble this season.

City missed out on their usual EFL Cup triumph this term, a trophy they had lifted four times in a row under Pep Guardiola.

However, they are six points clear at the top of the Premier League, albeit having played a game more than title rivals Liverpool, while they are into the quarter-finals of the FA Cup.

Southampton stand in the way of a semi-final trip to Wembley in that competition, while City also have one foot into the last eight of the Champions League.

Last year's runners-up thrashed Sporting CP 5-0 in the last-16 first leg last month, meaning the return fixture in Manchester on Wednesday should prove a formality.

"Definitely," Ederson told a news conference when asked if City had eyes on a treble, which would be the second of Guardiola's tenure after an EFL Cup, FA Cup and Premier League triumph in 2018-19.

"We know how difficult it is. A season here in England is very intense, especially around the Boxing Day period when there are a lot of games in a short space of time. That is very demanding on the entire group.

"We know how difficult it is, but we have the quality to do this. We've shown this previously and we're showing it at the moment. I think we're fully capable of meeting this achievement."

City are yet to win the Champions League, with last season's final defeat to Chelsea in Porto the closest the club has come.

"Last season we had the opportunity but lost in the final," Ederson said.

"Our goal is to go into every tournament to win. We have to take things step by step to progress. We know there are challenges in every competition. Every game has its own challenges and [you] have to take things step by step to achieve great things in the future."

City's victory in Lisbon represented the joint-biggest winning margin away from home in the knockout stages in Champions League history. The largest first-leg deficit to be overturned in the competition is four goals, Barcelona having famously thrashed Paris Saint-Germain 6-1 in March 2017 after losing the away leg 4-0.

City have won each of their past six home matches in the knockout stages of the Champions League and could tie a record that has been reached on five occasions previously, while Sporting have failed to keep a clean sheet in any of their most recent 13 away matches in the tournament, conceding 31 goals in the process (2.4 per game).

Manchester United interim manager Ralf Rangnick acknowledged "there is a gap between the two teams" after suffering a 4-1 thrashing at local rivals Manchester City.

United headed to the Etihad Stadium on Sunday unbeaten in 11 games in normal time across all competitions, but came unstuck against Pep Guardiola's Premier League leaders.

Kevin De Bruyne needed just five minutes to open the scoring and became the first player to score a league brace in the Manchester derby since Sergio Aguero in April 2015, after Jadon Sancho's first-half equaliser.

De Bruyne then turned provider for Riyad Mahrez to put the game beyond doubt at 3-1, before the Algeria international capped a sumptuous derby display with a late fourth goal for City.

That leaves United a point behind fourth-placed Arsenal, who defeated Watford 3-2 on the same day and have played three games fewer than Rangnick's side.

Rangnick pointed to the difference in quality between his team and City as he looked ahead to an important period, with United vying for Champions League success and a top-four push in the league.

"I think we played a good, if not decent first half. We were competitive. It is difficult to concede an early goal," he told Sky Sports after the game.

"We came back, scored a brilliant goal ourselves then conceded another on the counter. It was a very difficult game against one of the best teams in the world. We conceded a fourth in the last minute of the game. It is a difficult game that shows we have a long way to go to close that gap."

Pressed for an answer on whether the gulf between the two Manchester clubs showed, Rangnick added: "In the second half it did but the first half was a competitive game.

"Everyone knows how good they are. They are one of the top teams in the world and there is a gap between the two teams.

"We are fully aware we need to win games. This is one of the most difficult. It is accepting they were the better team today.

"But we look ahead to the next games and we need to win the next two home games - they are essential to us."

United's first-half display did offer some hope, with Paul Pogba and Bruno Fernandes acting as strikers and Scott McTominay, Fred, Sancho and Anthony Elanga doing the hard yards in behind the front pair.

But the Red Devils' task was already made more difficult before kick-off, when it was confirmed they would be without the injured Cristiano Ronaldo and Edinson Cavani.

"I don't know. I was hoping to have them available for this game," Rangnick responded when asked when Ronaldo and Cavani could return.

"We have two important games coming up against Spurs and Atletico and we have to put our full focus on that."

Meanwhile, City manager Guardiola was delighted with what he saw from the Citizens - who restored their six-point lead at the Premier League summit, albeit Liverpool do still boast a game in hand and make the trip to the Etihad in April.

"It was excellent from the first minute. We played really well and had to be patient in the first step," he told Sky Sports.

"Ralf [Rangnick] tried to change the mentality for Man United to be more aggressive but we made space, especially in the second half, to play behind [Scott] McTominay and Fred.

"Football is emotions. It's tactics, definitely, but it's also emotions. Without the ball, we are a team with desire and passion to regain the ball from the first minute to the 90th.

"We also want the ball as much as possible and, especially, second half we used it very well."

Guardiola also reserved special praise for Jack Grealish, who was preferred ahead of Raheem Sterling on the left flank.

"He was excellent. [At one] moment he will understand in the final third, 'this ball is from me'. He is very generous," Guardiola said of the former Aston Villa man.

"When you see Phil [Foden] and Riyad [Mahrez] in that moment, it is their ball. This is the next step for Jack, but in terms of decision-making, and using players in space, he was exceptional."

Manchester United stars Cristiano Ronaldo, Edinson Cavani and Raphael Varane were all ruled out of Sunday's derby clash with Manchester City.

Ronaldo, who is United's top scorer with 15 goals in 30 appearances across all competitions, was absent for the trip to the Etihad Stadium, while Cavani was also not fit enough to make the squad.

While the Portugal star leads the scoring charts for the Red Devils, he has managed just one goal in 2022 – a second-half strike against Brighton and Hove Albion on February 15.

Earlier reports suggested injuries were behind the absences of Cavani and Ronaldo, and Ralf Rangnick confirmed the latter hurt his hip in training on Friday.

While that left Marcus Rashford as Rangnick's only recognised striker, the England international was named on the bench with Bruno Fernandes leading the line and flanked by Jadon Sancho and Anthony Elanga.

Rangnick also was again without Luke Shaw, with Alex Telles operating at left-back, while Scott McTominay replaced Nemanja Matic, and Harry Maguire came in for Varane from their last outing against Watford.

Shaw and Varane were missing due to testing positive for COVID-19.

Manchester United interim manager Ralf Rangnick says the club's transfer strategy needs to improve and is one of the key reasons why they have fallen behind Manchester City and Liverpool.

United trail Sunday's Premier League opponents Manchester City by 19 points and have not finished above their Mancunian neighbours on the table since 2012-13 when Sir Alex Ferguson retired.

The Red Devils have spent more than £1 billion on players since Ferguson's departure yet have not been genuine title contenders in that time.

"It’s a question of consistency, continuity, knowing exactly how I want to play as a club, as a manager," former RB Leipzig and Red Bull Salzburg head coach Rangnick told reporters.

"Having a clear transfer strategy, signing players who fit into that system and that’s what both clubs have been doing in the last five or six years.

"If I look at their transfer success, they haven’t had many players who after one or two years somebody would have said, ‘maybe that wasn’t the right signing’. They’re pretty successful, both clubs and this is where I think Manchester United has to go again.

"Under Sir Alex they were there until 10 years ago but since then, there’s been quite a few different managers here at the club and in order to close the gap towards those two clubs, I wouldn’t say we have to do the same thing.

"We have our own identity, Manchester United as a club, we should always go down our own pathway but in total, professional football is pretty easy.

"You have to have a clear identity of how you want to play, how even the supporters want to see you play and this has always been attractive, offensive, proactive, entertaining football and then from there, make sure that the recruitment is right, that you get the best possible players, that you’re quick enough in the transfer market, knowing the transfer market and then signing the right players at the right moment.

"Then, on top of that, having the best possible manager, head coach, coaching staff who can develop those players.”

Angel Di Maria, Memphis Depay, Anthony Martial, Paul Pogba, Romelu Lukaku, Alexis Sanchez, Donny van de Beek, Jadon Sancho and Harry Maguire are among the big-money transfers United have made since Ferguson's exit.

Pep Guardiola has acknowledged that Manchester City are in need of a striker.

The Citizens have not had an out-and-out attacker in the traditional sense since Sergio Aguero left the club at the end of last season.

Attempts to recruit a quality replacement last summer ultimately proved to be thwarted for Guardiola, with multiple offers for Harry Kane knocked back, among others.

An approach to Cristiano Ronaldo was also hijacked by neighbours Manchester United, who sealed a homecoming for the Portuguese from Juventus.

Since then, a host of players including Raheem Sterling and Gabriel Jesus have helped to plug the gap up front, while Ferran Torres was occasionally used before his move to Barcelona

While the lack of a traditional player in that role has not dented City's prospects this season, nor hindered their grip on the summit, Guardiola has admitted that City will look to recruit for the role again at the end of the campaign.

"I think the club needs a striker, definitely," the Spaniard said ahead of Sunday's derby clash with United.

"You say we play fantastically well without a striker because we are winning. When we are not winning, you say we need a striker.

"[You say] 'how do these guys play without a striker? In the Premier League you have to play with a striker'. So, we need a striker, I think the club is going to try [to buy one]."

City did purchase Julian Alvarez in January, before loaning him immediately back to River Plate, but it remains to be seen whether the Argentina international could be a long-term solution.

Pep Guardiola hailed the "attractive" high-intensity philosophy that German-influenced managers have implemented in the Premier League, but insists he will stick with his own principles.

There are several Premier League bosses whose experiences include coaching stints in Germany, with Jesse Marsch, Ralf Rangnick, Thomas Tuchel, Jurgen Klopp and Ralph Hasenhuttl among them.

The fast-paced style of play, designed to profit from regaining possession high up the pitch, has many advocates, with current Manchester United interim boss Rangnick a key figure behind its success.

New Leeds United head coach Marsch was Rangnick's assistant at RB Leipzig, where Southampton's Hasenhuttl took charge when the current short-term Old Trafford chief departed in 2016.

Chelsea boss Tuchel pinpointed Rangnick as a mentor after playing under him at Ulm, while Liverpool's Klopp has utilised similar ideas to challenge Guardiola's Manchester City for the Premier League title.

Going into the weekend, City sat six points clear of Liverpool, who had the chance to cut the gap to three when they played West Ham on Saturday. The Manchester derby awaits City on Sunday.

"With Jesse Marsch arriving at Leeds it is already a tendency," Guardiola told Sky Sports of the Bundesliga influence. "Five teams, important ones, playing this way, it is because what happened in Germany arrived here.

"Five important teams and managers all playing this way. Transitions, playing inside, high pressing, everybody together, it doesn't matter if we lose the ball because I recover the second one and attack you again, you lose it again and you lose it again.

"This incredibly good methodology, it is the deep tendency here in England."

Asked whether the approach was for him, the Spaniard said: "It is so attractive when they do it well. It is so attractive for the spectators, and they have had success.

"Of course, I learn a lot in Germany. I adapt. Listen, I am from Catalunya, you know. My education, my football education, comes from there. And I learn a lot here, I learn a lot in Germany, but my principles come from there."

Guardiola's emergence through the Barcelona system means he is indoctrinated in that way of playing. Regardless of the trophy achievements of the likes of Klopp, the Spaniard says that when it comes to his method, he "cannot change it because they have success".

He expects a difficult task against United, who entered the weekend on the longest current unbeaten run in the Premier League (eight games), as City eye a league double over the Red Devils for just the second time under Guardiola.

But the former Bayern Munich and Barcelona chief insists he is learning that, whatever the result, he must be more patient on the touchline whichever way the game goes.

"I understand more that the players can make mistakes," he said. "Before, I was more anxious, more angry. Sometimes I am, but I understand because I know they want to do well. I know they want to win against Manchester United.

"I know they want to win the Premier League. I know they want to win the Champions League."

He spoke of always being "anxious and angry".

"But after the action is done, it is gone. I cannot correct this action. So why am I shouting about how they have behaved?" Guardiola said.

The 51-year-old City boss is learning that his players are not automatons, and that while he might complain that "they don't listen to me", he is reconciled to the limitations of his pitchside influence.

Guardiola added: "I have to understand at the end that as much as I want to change, I will not change."

Ralf Rangnick has identified the "secret" that has allowed Manchester City and Liverpool to streak so far ahead of Manchester United.

United's interim manager sends his team out to tackle City in Sunday's derby, knowing the once-mighty Red Devils are again not a factor in the Premier League title race.

Their best hope appears to be clinging to fourth place and making progress in this season's Champions League, with Rangnick expected to vacate his position at the end of the campaign.

The 63-year-old German is a wily campaigner who can see what United are so obviously missing is the stability that City and Liverpool have enjoyed in recent years.

Pep Guardiola and Jurgen Klopp are firmly established in their posts, having received extensive backing, and their teams are the clear big two in England for now.

Rangnick said of United's rivals: "They have a very clear identity and a clear idea of how they want to play, and I know Jurgen in person and I also know Pep from those three years in Germany when he was at Bayern Munich, and he also has a clear idea of how he wants to play.

"This idea is the headline for everything that happens in the club. This is the secret behind their success: that they exactly know how they want to play.

"They have a clear identity, or you could call it a corporate identity and this is their guideline for everything they do, not only for new players but also for staff members and experts in different areas of the game that have become more important in the last 10-15 years.

"This is what all clubs in Europe have in common. This is something that also at Manchester United needs to be developed and improved in the next couple of years."

Rangnick may yet have a role to play in establishing such a structure and ethos at United, with an advisory role potentially waiting for him.

For now, his focus is on the current first team and delivering short-term results. United's current eight-game unbeaten run is a positive trend, and if they stretch that to nine after Sunday's derby there will be considerably more cause for cheer.

The German boss said he has had no input so far regarding who the next manager might be, and played down his previous remarks that he might recommend himself to the board. He said he made those remarks "with a twinkle in my eye", suggesting they were not entirely serious.

Rangnick labelled Guardiola and Klopp "the two best coaches on the planet" and said: "You need to have the best possible people, and you need a clear idea of football, and then stick to that idea and take your decisions always with having in mind, 'what do we want to be, how do we want to play?'."

The former RB Leipzig boss said United would need to show "tactical discipline" to stand up to City's threat.

"It will be a lot of defensive work necessary, a lot of sprinting, running, against the ball and with the ball, waiting for transitional moments and taking our chances," he said.

"This is what it's all about I think. We created enough chances in the last 10-11 games, and at times we converted them, like at Leeds where we scored four goals, but it's correct we should have scored more goals, especially in the last match against Watford."

That clash with the Hornets at Old Trafford finished goalless, which was hardly the morale-boosting result United might have wanted before facing the Premier League leaders this weekend.

Cristiano Ronaldo has been "a joy to watch" in recent years, according to Pep Guardiola and the Spaniard believes football will never see the like of the Manchester United star's talents again.

The duo will face off once more in the Manchester derby on Sunday, having built a rivalry during their days in La Liga as Real Madrid forward and Barcelona coach respectively.

Manchester City boss Guardiola tried to coax Ronaldo to join his side from Juventus in the close season, before United swept in to seal a homecoming for the Portugal superstar.

But even after missing out on his services, Guardiola has nothing but praise for the evergreen attacker's skills, citing him and Lionel Messi as generational powerhouses.

"One of the greatest in the last 15 years alongside Messi," Guardiola told a pre-match press conference on Friday when asked on Ronaldo. "We aren't going to see it again.

"When you achieve these things, you're under scrutiny every day. He was too good and as a finisher, exceptional - a top player. It has [been] a joy to watch in these years.

"We have to exploit our game and strength to avoid him close to the ball. We have to control him. One of the greatest - a goalscoring machine.

"He is so strong mentally. He handles this pressure without a problem, [and] lives with expectation through his career in a positive way."

City head into their clash with United eying a first Premier League double over their local rivals since the 2018-19 campaign, in what will be the pair's maiden meeting with Ralf Rangnick in the opposite dugout.

The German, who is set to be in command of United through to the end of the season, has them on the longest current unbeaten streak in the top flight (eight games).

Their hosts, meanwhile, will be out to avoid rare successive losses at the Etihad Stadium, following defeat to Tottenham in a five-goal thriller on their previous home outing.

Ruben Dias is to miss Sunday's Manchester derby and is likely to be out of action for at least four weeks, so says Pep Guardiola.

Manchester City defender Dias sustained a hamstring problem during the FA Cup win over Peterborough United in midweek.

Guardiola has now confirmed he will be without the Portugal international, who has maintained his fine form from last season, for at least a month.

However, Guardiola refused to consider Dias' absence as a serious blow to his side's prospects in the derby, which could prove a pivotal game in the Premier League title race.

"Ruben will be unavailable," he told his pre-match press conference. "Muscular. Hamstring. Four to six weeks. It happens.

"In other seasons our best players have been out for months.

"I'd love him but he's not there, I will not cry. It is what it is. We have decent players available. We have 14-15 players. With these players we are going to fight and try to play good.

"[It's] impossible to fight if you don't play good. We play with our people and hopefully our people support as they always do."

Dias has started 24 of City's 27 league games so far this season, having featured 32 times in the competition last term.

City, who will also be without Nathan Ake, are looking to complete a Premier League double over United for just the second time in Guardiola's reign, after home and away wins in the 2018-19 season.

Yet they face a United side who have won their last three games at the Etihad Stadium, and who will be seeking to make it four wins in a row away at City for the first time since doing so between November 1993 and November 2000 at Maine Road, when the rivalry was emphatically dominated by the Red Devils.

United are also unbeaten in eight Premier League games, the current longest ongoing unbeaten run of all teams in the competition.

Two of City's three Premier League defeats have come at home this season, most recently with a 3-2 shock reverse against Tottenham last time out on home turf.

Pep Guardiola welcomed the show of support for Oleksandr Zinchenko as the Ukrainian defender captained Manchester City in their FA Cup win at Peterborough United.

With his country experiencing a Russian military invasion, Zinchenko stepped up to assume leadership on the football pitch after being handed the armband by Fernandinho.

It was a move designed to show solidarity with the 25-year-old as he waits for news from what Guardiola described as "this nightmare" in Zinchenko's homeland.

"It's not an easy period for Oleks," Guardiola told a news conference. "His family, his country, but playing football is the best for him at the moment."

In a separate BBC interview, Guardiola said of the left-back: "Unfortunately his citizens in Ukraine are living in a terrible and crazy and insane situation. All the people here at Peterborough, not just our fans, showed him warmth.

"Hopefully this nightmare can finish as soon as possible."

Goals from Riyad Mahrez and Jack Grealish in the second half carried City through to the quarter-finals.

Both were set up by Phil Foden, whose pass to Grealish for City's clincher particularly caught the eye.

Grealish later revealed it was inspired by watching clips of Guardiola's former Barcelona charge Lionel Messi in action.

"The pass from Phil was excellent. It was quite similar to the pass from Phil that he did to Joao [Cancelo] in Brugge in the Champions League, and the control was excellent from Jack," Guardiola said.

The City boss added: "They were brilliant goals. The quality for Riyad and the second goal the same. It was good.

"We created chances. All of them were brilliant. Riyad always had this quality in the final third – he is the best player in the final third that we have. He scored a fantastic goal. I'm so proud for the game he played."

There was cause for slight concern ahead of Sunday's derby against Manchester United, with Guardiola substituting starting centre-backs Ruben Dias and Nathan Ake at half-time due to what he hopes are only minor knocks. Aymeric Laporte and John Stones proved capable replacements.

The City manager said Dias was "not feeling good in his leg", while Ake suffered a blow when committing a first-half foul.

"That's why, for caution and to be alert, we made the substitutions," Guardiola said. "It was not planned. I would say it was a medical decision."

Oleksandr Zinchenko was to captain Manchester City at Peterborough United on Tuesday in his first appearance since Russia invaded Ukraine.

Ukraine international Zinchenko was on the bench at Everton on Saturday and pictured in tears as both teams showed their support for his nation at Goodison Park.

And further gestures were set to follow before the FA Cup fifth-round tie against Peterborough.

Zinchenko was to be at the forefront of those after he was named as City's skipper on the teamsheet, despite the club initially suggesting regular captain Fernandinho would lead the side.

Fernandinho, who spent eight years in Ukraine with Shakhtar Donetsk before joining City, offered the armband to Zinchenko in a sign of solidarity.

"Our captain decided to give the armband to him to show how important the situation is," Pep Guardiola told ITV Sport. 

"We are all the club behind this gesture, behind our captain, who represents his country."

Zinchenko and Fernandinho were among six changes to the City side, with Jack Grealish also brought in after a spell out through injury.

Guardiola had confirmed on Monday that Zinchenko would be involved, saying: "I think it would be good for him to play and show the reason why he is here – he is a magnificent player – to play football."
