Marcus Rashford must transfer his training-ground displays into matches if he is to hold down a starting spot for Manchester United, interim manager Ralf Rangnick has said.

The England international has this week been linked with a move away from Old Trafford, where he has spent his seven-year career to date, after reportedly growing frustrated.

He has struggled for playing time and was left out of United's XI for last weekend's defeat to Manchester City, despite the absence of a recognised centre-forward in the squad.

Rashford is pushing for a recall when United host Tottenham in the Premier League on Saturday, but Rangnick has not offered the academy product any assurances.

Instead, the German has challenged Rashford to prove his quality on the pitch when the time arrives.

"Marcus has to play on the same level he trains. This is all," Rangnick said at Friday's pre-match news conference.

"Marcus is training well, he's got an abundant amount of talent, almost everything you need for a modern striker.

"It's now about transforming the performance of the training sessions into the regular games."

Rashford has scored five goals and assisted two more in 24 appearances for United in all competitions this term, the forward having contributed to 0.49 goals per 90 minutes.

That compares to 0.69 for Jesse Lingard, who leads the way among United players, albeit having played far fewer minutes than most.

Bruno Fernandes, Cristiano Ronaldo (both 0.66) and Paul Pogba (0.62) are the other United players to rank higher than Rashford, with Edinson Cavani (0.48) marginally behind.

The 24-year-old's 145 minutes per goal involvement in the league this term is way down on his average of 111 in 2019-20 – his best season in terms of goals and assists.

Cristiano Ronaldo is available for Saturday's Premier League meeting with Tottenham, but Ralf Rangnick is unsure if the forward is happy at Manchester United.

The Portugal international was left out of United's squad for last weekend's 4-1 defeat to rivals Manchester City after sustaining a hip injury in training.

However, United great Roy Keane questioned if that was really the reason why Ronaldo was absent at the Etihad Stadium amid reports he had been dropped by Ralf Rangnick.

Ronaldo flew to Portugal to work on his fitness and Rangnick confirmed on Friday that the 37-year-old is now back in training and is expected to play a part against Spurs.

"He resumed for training yesterday," Rangnick said at his pre-match news conference. "He trained the whole training session and I expect him to train today as well. 

"He trained well, like the rest of the group. I would've thought he was available tomorrow.

Ronaldo's Manchester derby absence came on the back of a run of one goal and zero assists in 10 games for United in all competitions this calendar year.

That compares to 12 goals and three assists in his opening 19 games upon returning to United from Juventus at the end of August.

Asked about reports that Ronaldo travelled to Portugal without informing the club, having grown frustrated at Old Trafford, Rangnick attempted to draw a line under the matter.

"It doesn't make sense to look back on what happened the last six or seven days," Rangnick said. "For me what is important is what happens today and tomorrow. 

"I haven't asked him if he's happy at Manchester or at this club. For me it's important he's fit again.

"He resumed training yesterday and we shall see which formation and which will line-up we will play with tomorrow."

Ronaldo has been involved in seven goals in his last five league games against Tottenham, both scoring and assisting against them in three different matches in this run.

As well as having the five-time Ballon d'Or available, Rangnick confirmed Edinson Cavani is back from injury and Raphael Varane has recovered from coronavirus.

However, full-back Luke Shaw will miss out after again testing positive for COVID-19 on Thursday, while central midfielder Scott McTominay is doubtful due to a calf injury.

United have won just two of their last six league games, seeing them drop out of the top four at the expense of Arsenal, who are one point better off with three games in hand.

They will be aiming to get back on track as they seek a third straight league win against Spurs for the first time since a run of four between April 2009 and October 2010.

"We are fully aware about the importance of tomorrow's game and the game on Tuesday against Atletico Madrid," Rangnick said. 

"The most important game is the game tomorrow against Tottenham – we have to win that game. 

"We've had a good week of training and the players are fully aware about the importance of the game. The focus has been there, as well as the togetherness in training."

There really isn't much to split Manchester United and Tottenham right now.

Ahead of Saturday's game at Old Trafford, the Red Devils are two points better off in the Premier League table but having played two matches more. Just a single goal separates them in the goal difference column, too.

They have each won three of their past seven league games, they are heavily reliant on two players scoring the vast majority of their goals, and even their managers, although on very different contracts, are facing uncertain futures. If you stood between the dressing rooms prior to kick-off, you wouldn't be surprised to hear "Lads, it's Tottenham" and "Lads, it's United" bellowed simultaneously behind the closed doors.

Of course, this could be a hugely important fixture beyond deciding which team is playing slightly less mediocre stuff. The top-four race in the Premier League looks likely to run into the deciding matchdays in May, and a win this weekend for either side would give them a huge boost.

It could also offer some clues as to which of Ralf Rangnick and Antonio Conte has so far done a better job, because that, too, is a very difficult question to answer.

Since Rangnick replaced Ole Gunnar Solskjaer as interim manager in late November, United have played 14 in the Premier League, won seven, drawn five and lost two, giving them an average of 1.86 points per game. They have scored 21 goals and conceded 14.

Their victories have come against Brentford, Brighton and Hove Albion, Burnley, Crystal Palace, Leeds United, Norwich City and West Ham. Just two of these teams are currently in the top 10 in the table.

Roughly a month earlier, Conte stepped in for the sacked Nuno Espirito Santo, who lost his job after Spurs were beaten 3-1 at home to United. 

In 16 games under the Italian, Spurs have won nine, drawn three and lost four, averaging 1.88 points per game. They have scored 31 times and conceded 16.

Their wins have come against Leeds United, Brentford, Palace, Everton, Leicester City, Manchester City, Norwich and Watford. Just two of these teams are currently in the top 10 in the table.

We told you it was difficult.

Such distinctly average form has not helped to paint a clear picture of either manager's efforts. Spurs will go into this game in a better mood, of course, given they just thrashed an awful Everton side 5-0, while United were humiliated in a 4-1 loss to Manchester City. Still, it's only been a couple of weeks since Conte suggested he might have to resign as he just couldn't handle the thought of more defeats, while United had just scored six across consecutive wins over Brighton and Leeds. Inconsistency is the only constant where United and Spurs are concerned.

There have been definite improvements, though. For one thing, despite Raphael Varane's injury troubles and the overbearing scrutiny on Harry Maguire every time he draws breath, United's defence has got better since the shambolic final weeks under Solskjaer.

In their opening 14 league games this season, United conceded 22 goals – the fifth-most in the division – and kept only two clean sheets. Under Rangnick, they have let in 16 goals – four of those coming at City last weekend – and kept five clean sheets (we are excluding own goals here). They are facing a similar number of shots, roughly 13 per game, but their expected goals against figure has improved from 21.43 to 18.35, suggesting that, under Rangnick, they have limited opponents to more speculative attempts. They have also cut down a deeply worrying number of mistakes: before Rangnick, they committed a league-high 12 errors leading to shots, which has fallen to just three since the German took charge.

Defensive improvement has not been quite as clear under Conte. Although they have conceded as many goals (16) in Conte's 16 matches in charge as they did in 10 under Nuno, Spurs' xGA figure has increased from 15.48 to 19.01, indicating that their seven clean sheets have owed something to Hugo Lloris and a little luck (again, that figure ignores own goals). And while United's error count has dropped, Spurs have committed 11 leading to shots, the second-worst figure in the Premier League since Conte's return. It would be enough to make the former Chelsea boss tear his hair out, if... no, we won't go there.

What about at the other end? A much-discussed issue under Rangnick, and the reason behind all those draws, has been United's inability to take chances. Cristiano Ronaldo, for instance, has only scored one goal in 2022. The numbers highlight an obvious problem: in the league under Solskjaer, United exceeded their expected total this season by just over four (excluding own goals); under Rangnick, they have underperformed by 4.4.

Yet their problems in attack are not for the want of opportunities. Since Rangnick's arrival, only Man City and Liverpool have created more chances and attempted more shots in the Premier League, and only Man City and Spurs have generated more 'big' chances. The problem is that only 68 of United's 208 most recent shots have been on target, and only Liverpool have attempted more from outside the box in that time. When the going gets tough, the shooting gets desperate.

Over the same period, they are fourth for xG and expected goals on target, which measures the quality of an attempt itself. However, the difference between the two is nearly 4.0, and 3.03 if you exclude penalties. Only relegation battlers Burnley (3.53) have had a worse such difference during Rangnick's time in England, which tells you a lot about the standard of United's recent finishing even before you take the opposition goalkeeper's performance into account. They can at least make the argument that, should they keep creating chances at this rate, their luck should begin to turn... eventually.

Spurs' attacking fortunes have felt a bit mixed under Conte. In their past five matches, they have scored three at Man City, four at Leeds and five at home to Everton but drawn blanks away to Burnley and Middlesbrough.

Excluding own goals, they have scored 28 times in the league under Conte from 30.4 xG, giving them pretty similar figures to those under Nuno (eight goals from 10 xG). The average xG value of their shots has increased a touch, though, so they can argue their attacking play is sharpening up.

That's a good sign given Spurs are chasing a couple of milestones at Old Trafford: they could score at least four goals for the third league game in a row for the first time since February 2004, while Harry Kane needs only one away goal to match Wayne Rooney's competition record of 94.

It would be quite the result if Spurs could beat both Manchester clubs away in the same season, and it would give their Champions League hopes a significant shot in the arm. As for which side is showing the best progress... well, perhaps we should let this top-four chase run its course first.

Manchester United's search for a new permanent manager continues.

The Red Devils parted ways with Ole Gunnar Solskjaer last year after an underwhelming campaign despite the return of Cristiano Ronaldo.

Ralf Rangnick has taken over on an interim basis, buying United time to get the right man for the job.

FootballTransfers claims that Ronaldo has decided that he will leave Manchester United if they do not qualify for the Champions League, with a move to join Lionel Messi at Paris Saint-Germain on his agenda.

Speculation about Ronaldo's future at Old Trafford ramped up after he missed Sunday's Manchester derby due to a hip flexor injury and flew to Portugal.

The report that claims that Ronaldo returning to Juventus has been ruled out, along with his original Portuguese club Sporting CP, with the five-time Ballon d'Or courting a move to Paris.

Former Manchester United striker Teddy Sheringham has criticised the direction of the Red Devils after their humbling 4-1 defeat to Manchester City.

United sit fifth in the Premier League and suffered a big blow in their race for Champions League qualification at the Etihad Stadium on Sunday.

They failed to register a single shot in the second half and had just eight per cent possession in the last 15 minutes of the game as Pep Guardiola's team toyed with their neighbours.

Reports late on Saturday suggested Cristiano Ronaldo would not feature in the derby clash, with interim manager Ralf Rangnick confirming before kick-off that the Portugal forward was suffering from a hip problem.

Former United captain Roy Keane suggested before the game that Ronaldo's omission may be down to other reasons after being left out for such an important fixture, though Rangnick later denied this.

Sheringham played for United between 1997 and 2001 and played a crucial role in the 1999 Champions League final win against Bayern Munich.

Speaking on Sky Sports' Monday Night Football, Sheringham expressed his concern over a lack of direction at Old Trafford.

"I've been on both sides of the situation," he said. "It grinds you down when these teams keep dominating you. When you're playing in a team that's so focused and all rowing in the same way, it's all great.

"When you're playing for a manager that some people are thinking 'He won't be here at the end of the season, I don't really have to try my hardest. He'll be gone, I'll work for the next manager', there's vibes like that you can see all over the pitch. Players are getting left out. 'Is he injured? Is he not?'

"There's just problems at the club, and I think that comes from the leadership in the football club.

"You look at Manchester City. They are being led by a top man that is devoted to Manchester City being better. The best that they can be.

"When you look at Manchester United, they had an interim manager [Ole Gunnar Solskjaer], they sacked him. They get another interim manager in, what's going on at this top football club? What is going on?

"And that filters down. If you're getting someone who's there for the long stay and the desire to make them better, everyone can follow with you.

"But when it's not, it makes it hard for everyone to follow in that same way because it's going to change at the end of the season again we've got to start again with another manager with new ideas again."

Manchester United great Paul Scholes was once again left questioning the club's wisdom in hiring Ralf Rangnick as interim manager after Sunday's 4-1 derby humiliation by Manchester City.

Kevin De Bruyne and Riyad Mahrez got two goals apiece at the Etihad Stadium, as City restored their lead at the Premier League summit to six points over Liverpool.

United – without Cristiano Ronaldo due to a hip injury – started the game well and were good value for their 22nd-minute equaliser by Jadon Sancho, but thereafter it was one-way traffic as Rangnick suffered only his second Premier League defeat in 14 matches.

Despite that record, Scholes cannot get past Rangnick's lack of recent experience in coaching, having only actually been in charge of a team for two of the previous 10 seasons, instead spending much of his time as a sporting director.

Rangnick was hired as Ole Gunnar Solskjaer's replacement at the end of November until the end of the season, at which point he will move into a consultancy role.

The move was initially widely praised as it seemed to suggest United were looking to establish an on-field identity that Rangnick would subsequently be able to influence with big-picture decisions, but Scholes is struggling to see the reasoning behind hiring him as the interim manager.

"What do we expect? We've brought in an interim coach who hasn't coached at an elite team," he told Premier League Productions.

"He hasn't coached a big team, he hasn't coached at a big football club like United where there's so much expected of Manchester United, whoever you're playing against, it doesn't matter. He's never been at a top club. He's coached a club for two years out of the last 10 years.

"How have United behind the scenes come to the conclusion that this man is going to be the right man for six or seven months? It baffles me. The players are lost on the football pitch.

"The first 20 minutes I was surprised, they played really well, they were comfortable on the ball, [Paul] Pogba up front looked alright. His [Rangnick's] subs have worked the last few weeks don't get me wrong, but it was a deflated team.

"As much as you can have a go at United, they were playing against possibly one of the best teams we've seen. In the second half, the players looked lost. They looked like they didn't have a clue what they were doing."

Prior to the weekend, Rangnick had been praised for improving United defensively. Before Sunday's hammering, they had conceded 10 goals in 13 league games under the German, having let in 21 in 12 with Solskjaer at the helm – only Norwich City and Newcastle United (27 each) had worse records at the time of the Norwegian's sacking.

But Scholes believes their change in fortunes at the back is a red herring, and the data seems to back him up to a certain degree.

David de Gea's saves since Rangnick's arrival have accounted for the prevention of six goals the average goalkeeper would not be expected to prevent, second only to Jose Sa (6.1).

Sa (192) is also the only keeper to face more shots than De Gea (180) in that time as well, suggesting United are not much better defensively than before – they are just relying on their goalkeeper's improved form.

"They were lucky it's not five or six. Again the goalkeeper, five or six saves," Scholes continued.

"We spoke before the game saying defensively since Ole's gone [Rangnick]'s shored things up – he hadn't. Never in a million years.

"He's kidding himself if he thinks that. The keeper has stopped him from getting batterings for a long time. [Sunday] was exactly the same."

Manchester United goalkeeper David de Gea promised to fight to get "the club back to where it deserves to be" after a 4-1 thrashing at Manchester City.

United headed to the Etihad Stadium on Sunday unbeaten in 11 games in normal time across all competitions, while they were also on the longest unbeaten streak in the Premier League (eight games).

But doubles from Kevin De Bruyne and Riyad Mahrez proved decisive as Ralf Rangnick's side came crashing back down to reality, with their only consolation Jadon Sancho's first-half equaliser.

That leaves United a point behind fourth-placed Arsenal, who claimed a 3-2 win at Watford and have played three games fewer than their fellow top-four chasers.

De Gea vowed to battle to return United back to English football's top table after yet another derby-day humbling against Pep Guardiola's Premier League leaders.

"We will, one day, get this club back to where it deserves to be," he posted on Twitter after the game.

"Today was another bad moment in a difficult season but when we still have this shirt to defend we will not give up."

It has been a difficult season for United, who parted ways with club legend Ole Gunnar Solskjaer in late November after a dismal run of form.

Spain goalkeeper De Gea has been a standout performer for a mostly underwhelming United side, but matters could be worse for the Red Devils if it were not for the 31-year-old.

Only a shaky Leeds United (166), Norwich City (156) and Brentford (145) – all relegation battlers – have conceded more shots on target than United in the league this campaign (140).

That has forced De Gea, who has just seven top-flight clean sheets to his name this term, to make a league-leading 104 saves, with Leeds' Illan Meslier his closest company after managing 102 stops.

The excellence of De Gea stands out when compared to other goalkeepers in terms of the differential between expected goals on target conceded and the number of times they have been beaten.

Expected goals (xG) on target conceded – a way of measuring not just the quality of a chance but the quality of the attempt itself – when subtracted from goals against measures a goalkeeper's shot-stopping prowess.

De Gea has prevented 4.21 by that way of comparison, ranking only behind Wolves' Jose Sa (8.44) in the Premier League.

United will be hoping to make amends for their derby-day performance when they host Tottenham next Saturday, before the return leg of their Champions League last-16 clash with Atletico Madrid three days later.

Manchester United interim manager Ralf Rangnick defended his medical team after Roy Keane questioned Cristiano Ronaldo's absence for Sunday's crushing 4-1 derby defeat to Manchester City.

Reports late on Saturday suggested Ronaldo would not feature at the Etihad Stadium on Sunday, with Rangnick confirming before kick-off that the Portugal forward was suffering from a hip problem.

United were also without Edinson Cavani, who was missing for a sixth consecutive game due to injury as they fell to a humiliating loss at neighbours City.

Former United captain Keane, speaking on Sky Sports before the game, suggested Ronaldo's omission may be down to other reasons after being left out for such an important fixture.

Keane insisted the decision did not "add up", with Rangnick citing a hip flexor problem that kept the forward out of training on Friday, and the German responded to the comments after the match.

"I have to believe my medical department," Rangnick told reporters when asked about Keane's thoughts on the Ronaldo situation.

"Our doctor came to see me Friday morning before training and told me that Cristiano could not train because of some problems with his hip flexor and the same was true on Saturday and that's why he couldn't be a part of the squad."

Rangnick appeared frustrated to be without Cavani once more ahead of the clash with Pep Guardiola's side, suggesting the Uruguay international ruled himself out of contention.

After the game, the former RB Leipzig boss again commented on Cavani being ruled out of the derby, insisting he could not make a player feature if they did not feel fit enough.

"What does it help if I tell you it is frustrating? It is just a fact. If players tell the doctor and the medical department they are injured and cannot play, I have to accept it," he added. 

"I cannot force a player to play if he's not available because of an injury."

Pressed for an answer on whether Cavani decides when he is available, Rangnick responded: "Edi trained in the last three days, he trained well but he still felt after those three training sessions yesterday afternoon that he is still not fit to play.

"This is a fact. As a manager, I cannot force a player if he does not feel fit enough or well enough to play.

"We have to be – and I am – happy with the players we have. This is clear. We lost two, if not three strikers since Christmas, everybody knows.

"But this is a fact and we have to deal with it. I am not complaining about that."

The defeat at local rivals City leaves United a point adrift of fourth-placed Arsenal, who were 3-2 victors at Watford earlier in the day and have played three games fewer.

But Rangnick wants to focus on his team's push in the Champions League and hunt for a place in England's top four in the coming weeks, despite continued questions over who will take over at Old Trafford when his short-term contract concludes.

"Look, I'm still the manager of this team for another 10 games in the Premier League and hopefully a few more games in the Champions League," he continued.

"It doesn't make sense now to start speculation about how many players would we need and in what positions, this is my issue.

"Right now it's about preparing the team for the Tottenham game and after that, for a very important game against Atletico [Madrid] in the Champions League."

Roy Keane called for Manchester United to dump their derby flops as he attacked "shameful" effort levels in the 4-1 defeat to Manchester City.

Along with fellow 1999 treble winners Gary Neville and Peter Schmeichel, Keane said the performance from United was unacceptable at the Etihad Stadium.

Doubles from Kevin De Bruyne and Riyad Mahrez left United to reflect on a wretched afternoon at the home of their neighbours.

A first-half strike from Jadon Sancho had briefly brought United level, as they began the game well enough before fading alarmingly.

Keane said on Sky Sports: "They did give up, and for a player in any game to give up, it's unforgivable really.

"The beauty of top-level sport is there's no hiding place. I know United have done well here the last couple of years. We saw all the United shortcomings today.

"There's ways to lose football matches. We've all lost football matches. But the way United lost it today, they stopped running, they gave up. There are players not running back, that's what I don't understand."

Ralf Rangnick, the interim manager, had led United on an eight-game unbeaten run in the Premier League before this crushing blow.

"The manager will be criticised, and the tactics," said Keane. "But players not running back when you're playing for Man United, it's really unacceptable, it really is. They threw the towel in, which is shameful.

"It's hard when you're out there and you're up against a really good team and they're keeping the ball and you can't get it back, but I go back to it, we see some of the goals and you've got to run back, you've got to tackle.

"United players have shown quality over the years but we've just seen a reflection of where the team is and where the club is. It's just so far behind the other teams."

Sunday's results saw United slip to fifth, as Arsenal went above them with a 3-2 win at Watford earlier in the day.

Keane suspects there is more to United's troubles than may meet the eye, casting a degree of doubt before kick-off on the reason for Cristiano Ronaldo's absence, which was put down to a hip problem.

But he sees no excuse for United's players letting their focus drift.

"Whatever's gone in the dressing room, and we hear noises all the time, and we hear about problems obviously with the new manager maybe coming in, and recruitment," he said.

"But your own bit of pride eventually has to kick in at some stage. There were five or six players who should never play for Manchester United again. Just shameful, shameful that you can't run back and put your body on the line.

"I thought City had a couple of gears to go. They toyed with them. They [United] gave up, and shame on them."

Schmeichel, speaking on BBC Radio 5 Live, felt United were ripe for being picked off and need to look at themselves.

The former goalkeeper said: "I thought Rangnick should have changed things at half-time. He may have had words, but the second half was worse; at no point were United in the game apart from on the scoreline.

"Far too many players are either not good enough, or don't care enough. Having an interim manager means he can't do much; he knows he's not going to be there, so what can he change?

"There are players whose contracts are running down. [Paul] Pogba started the game, big question marks over whether he's going to stay. [Substitute Jesse] Lingard has said he doesn't want to be there. But for all that, Man City showed, in difficult circumstances, that they are the best in the country."

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."

Kevin De Bruyne was pleased with how Manchester City responded to Liverpool's win against West Ham, after a "different" Manchester United derby challenge on Sunday.

Jurgen Klopp's side closed the gap on Pep Guardiola's Premier League leaders to three points with a 1-0 victory over West Ham on Saturday.

But any sense of concern was quickly quashed when De Bruyne opened the scoring in the Manchester derby at the Etihad Stadium after just five minutes.

That was his 50th goal in the competition, and he soon added a 51st to his name, albeit after Jadon Sancho had levelled up for Ralf Rangnick's visitors.

Belgium international De Bruyne, who became the first City player to score a brace in this league fixture since Sergio Aguero in April 2015, then teed up Riyad Mahrez to put the hosts 3-1 up.

With that assist, De Bruyne recorded his 89th goal involvement in just 100 Premier League home games, spread across his time with Chelsea and predominantly City, and the midfielder was satisfied with his side's 4-1 win. Mahrez had added gloss to the scoreline in the closing stages, firing in off the face of David de Gea.

"I think Man United played differently to other occasions. They tried to press us and did well in the first half," De Bruyne told Sky Sports.

"We had a few more difficulties to get the ball around, but in the second half we created more opportunities."

De Bruyne was unable to explain why City have previously struggled at home to United but done well away, though he was delighted with this result against Rangnick's side.

"I can't explain why we always win over there [Old Trafford] but have more difficulty at home," he said. "Today, we played really well and deserved the three points.

"It's about winning game by game. They [Liverpool] won yesterday, but we responded in the right way. Sometimes we don't get the result, but we always play the right way and we will fight until the end of the season."

Mahrez sealed the derby success with the late strike that took him to 101 goal involvements for City across all competitions. It was his 21st goal of the campaign.

But the Algeria international acknowledged he had to stay patient for his opportunities, after a limited first-half display that saw the majority of chances come down City's left side.

"I think I touched four balls in the first 30 minutes, but in my head, I had to stay focused," Mahrez told Sky Sports.

"The first half was good and they [Man Utd] tried to play on the counter. Second half, we were more patient and more controlled and made the difference."

Discussing his goals, Mahrez added: "The first one, you just have to try and hit the target and the second one, I tried to put it high and it hit his face and went in. I will take both of them."

Guardiola's side will look to protect their lead at the Premier League summit when they travel to Crystal Palace in their next league outing, though Liverpool do still have a game in hand on City.

It was deemed a pivotal match in the title race. Liverpool would have been able to go top of the Premier League table – or at least within a point of it – with a win in their game in hand if Manchester City slipped up in the Manchester derby.

But upon its conclusion at the Etihad Stadium on Sunday, it was difficult to imagine Liverpool players doing anything but lifting their jaws off the floor after City blew Manchester United away in stunning fashion, beating Ralf Rangnick's side 4-1.

Not that it always looked likely to be so one-sided. A Cristiano Ronaldo-less United certainly made things interesting at the start, and the absence of the Portuguese forward – due to a hip injury – gave them an enigmatic aura, to some degree.

It emerged on Saturday night that Ronaldo was a doubt when reports began to suggest the Portugal captain had not been present with the rest of the squad at their team hotel.

City would surely have been preparing to face Ronaldo all week, and so United's set-up will have come as something of a shock – even more so when in the early exchanges it looked like the visitors were attempting to go punch-for-punch with the champions, something few teams survive.

In fact, early on there were signs of role reversal. United had spells of possession, City were playing for counters. Under Ole Gunnar Solskjaer, counter-attacking became something of a staple for the Red Devils in these fixtures.

But in the absence of Ronaldo, it was as if United were finally playing with a full complement of players, such has been his lack of influence outside the penalty area – you could potentially include inside the area as well given his recent wastefulness.

With Bruno Fernandes and Paul Pogba supporting wide forwards Jadon Sancho and Anthony Elanga, United looked fluid, intricate and generally dangerous in attack, almost mimicking City's striker-less style for 2021-22, the hosts' fifth-minute opener from Kevin De Bruyne not appearing to upset the away side's flow a great deal.

Jadon Sancho's excellent equaliser showed precisely what United were capable of, as they cut through City and the England international exhibited great composure by skipping around Rodri and curling into the bottom-right corner.

Though by that point, in the 22nd minute, City had already started to get to grips with United's slightly surprising set-up, as Rangnick's men started to show cracks.

In the first 15 minutes, the share of possession was almost 50/50 – over the course of a derby during Pep Guardiola's time in Manchester, United haven't had more than 40 per cent at the Etihad Stadium. But over the following third of the first half, City's share increased to 72.5 per cent, and it was unsurprising to see them regain the lead through De Bruyne just six minutes after Sancho's leveller.

If United were trying to mimic City, the latter were proving themselves to be the real deal.

Pep Guardiola seemingly targeted Aaron Wan-Bissaka – or United's right flank in general – as the weak link, with the right-back struggling to cope as Joao Cancelo, Jack Grealish and Bernardo Silva – even Phil Foden too at times – ganged up on him. City's first two goals originated from that area of the pitch and, in truth, even more could have.

United reached the break just one goal behind, and given their promising start and the open nature of the first period, there was reason to believe a way back wasn't out of the question.

But City were on a different planet after half-time.

Their control of the ball found another level, as did their cohesion when pressing, with United having immense difficulty passing through the City midfield.

Pogba faded into anonymity, Fernandes and Sancho too, while Grealish galloped with joy and De Bruyne ran the show, out-crafting and out-muscling his counterparts at almost every opportunity.

Adding to his brace, the Belgian also played the inch-perfect corner delivery that led to Riyad Mahrez's gorgeous half-volleyed third, which most would have accepted was game over for United. Though fans would have hoped the players weren't of the same opinion.

Yet the response to that 68th-minute goal was non-existent. City had 87 per cent of the ball between the 76th minute and full-time as United just seemed to throw in the towel – the concession of a late fourth to Mahrez was a just punishment for their reaction.

City's performance was a timely and fitting reminder that their superiority cannot be simply copied and pasted.

Rangnick said on Friday that City are an example because every decision in the club revolves around certain ideals and a joint-up philosophical approach to football – the second half on Sunday embodied that as they played United off the park playing the ferocious football they are known for.

Before this weekend, United had been reduced to the role of prospective party-poopers – it's a damning indictment of where they are now that even this was evidently way beyond their capacity.
