For the first time since 2005, neither Lionel Messi nor Cristiano Ronaldo will be involved in the Champions League quarter-finals.  

While Barcelona's exit to last season's runners-up Paris Saint-Germain was perhaps not too much of a surprise, few saw Juventus coming out on the wrong end of an upset against Porto in the last 16.  

So, could we be witnessing a changing of the guard in the competition? Is it a case of out with the old, in with the new? 

While Messi and Ronaldo have dominated in Europe through the years, a collection of some of the most promising talents in the world game have the chance to take centre stage now.

Erling Haaland (Borussia Dortmund)

Even by his own prolific standards, Haaland has been in sensational scoring form in the tournament so far.

His 10 goals in six games includes scoring a brace in each leg of the last-16 tie with Sevilla, helping Borussia Dortmund progress to the quarters.  

The Norwegian striker managed the same number in a Champions League campaign last season that saw him represent both BVB and Salzburg. Forget just breaking the record as the fastest to 20 goals, he has shattered it. Harry Kane was previously the quickest to reach that number, doing so in 24 games – Haaland managed it in just 14. 

His big chance conversion rate this season sits at a clinical 81.9 per cent, while he has also demonstrated his all-round impact by creating eight chances for his BVB colleagues.  

Next in his sights is Manchester City, a team with family ties as his father, Alf-Inge, played for the English club in the early 2000s. Haaland has been linked with them too, along with plenty of other clubs, and Pep Guardiola has been suitably impressed by a player who does not turn 21 until July.  

"The numbers speak for themselves, of course he is one of the best strikers in the world right now at his age," said Guardiola, who will be well aware that Haaland has the potential to ruin City's hopes of European glory. 

Kylian Mbappe (Paris Saint-Germain)

Mbappe has six goals to his name in European outings in 2020-21, the same tally team-mate Neymar has managed for a PSG squad aiming to go one better than last year.

The France international hit a hat-trick in a 4-1 thrashing of Barcelona at Camp Nou, joining Faustino Asprilla and Andriy Shevchenko as the only players to record a Champions League treble against the Spanish heavyweights.  

He was also on target when scoring a penalty in the drawn second leg, in the process becoming the youngest player to reach 25 goals in the competition, aged 22 years and 80 days. Messi was on the same pitch at the time his record was broken. 

Mbappe has also demonstrated how he can provide for others, too. No forward from any of the teams still in contention can top his three assists, while only Karim Benzema (15) has bettered his total of 14 chances created. 

PSG will be hoping the forward can continue his fine form when they take on Bayern Munich in a repeat of last year's final.

Phil Foden (Manchester City)

After three starts in the Champions League last season, Foden has risen from the periphery to become a prominent figure for Guardiola.  

Only goalkeeper Ederson has played more minutes in the campaign so far for City than the versatile 20-year-old, who has contributed a goal and two assists to help ensure smooth progress to the last eight.  

Foden has created the most chances for City during his appearances, his tally of 12 putting him just ahead of Kevin De Bruyne (11), while he has also been successful with 64.7 per cent of his attempted dribbles.  

The playmaker is set to feature in the Champions League knockout stage for a fourth season before turning 21 – a feat only previously achieved by Cesc Fabregas (2004-05 to 2007-08) and Theo Walcott (2006-07 to 2009-10).  

In the Premier League, Foden's 20 goal involvements (11 goals, nine assists) is comfortably the most by anyone aged 21 or under, showing just why he is no longer one to watch for the future but a player for the present, both for club and country.

Alphonso Davies (Bayern Munich)

It is not often a full-back catches the eye to the level that Davies managed during Bayern's triumphant Champions League run in 2019-20.  

The most eye-catching moment of all surely came in his side's 8-2 rout of Barcelona in a quarter-final result that sent shock waves across European football, as he initially beat two opposing players before breezing beyond poor Nelson Semedo to set up a goal for Joshua Kimmich, one of his three assists in the competition.  

Having arrived at the Bundesliga club as a left winger, the conversion to defence was made as quickly as he sprints up and down his flank (he clocked a top speed of 36.51 kilometres per hour in a Bundesliga game against Werder Bremen last year, the quickest speed recorded since such data began to be collected).  

His participation in the group stage this season was limited by an ankle injury, with the 4-1 first-leg victory over Lazio in the last 16 just his second start.  

However, the Canada international had no problems upon his return, having 101 touches (second only to team-mate David Alaba) while topping the list for Bayern in terms of tackles (four) and number of times possession was gained from the opposition (seven).

Wayne Rooney believes Phil Foden and Jack Grealish are too good to be left out of the England starting XI for Euro 2020.

Manchester City youngster Foden starred with a goal and an assist in the 4-1 away win at Premier League champions Liverpool last week.

He is gaining momentum after being handed more opportunities by manager Pep Guardiola.

Grealish, meanwhile, has thrived for Aston Villa this season, establishing himself as one of the Premier League's leading players with six top-flight goals and 10 assists.

Rooney is England's record goalscorer and thinks the form of the two attacking midfielders has become impossible to ignore ahead of the tournament.

"They have to be in the squad and arguably have to play because they are that good," the Derby County boss said about Foden and Grealish.

"Phil Foden has been one of the best players in the league this season, I think Guardiola has managed him really well.

"For Phil, it's about keeping doing what he's doing. He's one of the best players in the league this season.

"Foden is performing excellently — scoring, assisting — and hopefully he can carry that form on with England. He is entertaining to watch. 

"When my lad [Kai] used to go into City, I used to see Phil there.

"I spoke to him a couple of times and I could see he's a very level-headed lad. He was there a lot of the time, but it was just general chat, not me giving him advice.

"There are a few players — not just him. I think Jack Grealish brings something different for the national team."

Foden made his England debut away to Iceland in September but was promptly removed from the squad along with Mason Greenwood for breaking coronavirus protocols.

He responded by scoring a double - his first international goals - in the home match against Iceland in November.

Grealish, meanwhile, has five England caps and manager Gareth Southgate has spoken about the dilemma he faces over whether to play him or Chelsea's Mason Mount.

Phil Foden must be "calm" and "humble" as the plaudits flow his way, according to Manchester City manager Pep Guardiola.

Foden completed the scoring in Sunday's 4-1 win over Premier League champions Liverpool at Anfield, having also had a hand in each of Ilkay Gundogan's two second-half goals.

The 20-year-old attacking midfielder has 10 goals for City in all competitions this season and has played an integral part in them establishing a five-point lead at the top of the table.

However, Guardiola was critical of Foden's performance in the false nine role before half-time on Merseyside and, speaking ahead of Wednesday's FA Cup trip to Swansea City, said he felt Raheem Sterling was City's standout weekend performer.

"I said to [Foden], 'Don't read much, don't listen much, keep your feet on the grass and keep going'," Guardiola said, before waxing lyrical about Sterling after the England star won a penalty and scored a close-range header against his former club.

"Nobody talks much about Raheem and, at Anfield, Raheem made his best game of the last two months. By far.

"He was key in the first goal, for the penalty in the first half. Every action he made was decisive in the final third.

"Of course Phil was so important in the goals, especially in the fantastic last one.

"But Raheem was fundamental for us and hopefully, because he was a little bit not in the best form in the last month, he can continue to maintain the level he played at Anfield."

Foden will be reunited with Steve Cooper on Wednesday when Guardiola's City chase an English record - a 15th consecutive win for a top flight team.

The Swansea boss coached England to success in the 2017 U-17 World Cup, where the young Mancunian was named player of the tournament.

From that point, Guardiola has faced repeated calls to grant the playmaker more minutes at City.

A strand of post-match analysis at the weekend argued the former Barcelona boss had nurtured his latest star perfectly, but Guardiola does not necessarily view it that way and also stated Foden should not consider himself an automatic selection.

"I didn’t plan to handle the way we did it with Phil," Guardiola said. "Sometimes he played and he didn’t deserve to play.

"Normally we want to increase and talk a lot, a lot, a lot about Phil but after that we'll punish him, you know? For one mistake in this private life, we know exactly what happened [Foden was sent home from England duty last September for breaking coronavirus protocols].

"Now it's just [about being] calm. I know Phil is ready to play, His physical condition is extraordinary.

"I will handle it the same way and have handled it. When I believe he can help us he is going to play; when I believe another one deserves to play he is not going to play."

Indeed, with Foden the toast of the present moment in English football, Guardiola challenged him to turn a rich vein of form into the sort of longevity that separates the best from the rest.

"He has to be calm and understand tough periods will come. It depends on him being humble and his love for the game," Guardiola added of a player who recently brought up 100 senior appearances for City.

"We’ll see if he can handle it. Now the people expect him every game to do exceptional things, this is the most important thing.

"It's difficult to play 100 games but the important thing is to do 100 more and 100 more at this level. This is the toughest.

"This is why the best players did not do one action at Anfield; they play five years in a row, being consistent, not injured. Playing, playing, playing.

"This is the next target for Phil, maintain there as high as possible, as much and as long as possible.

"It depends absolutely on him. Hopefully he can do it."

Pep Guardiola hopes Phil Foden understands there is plenty of room for improvement but said it is a joy to have the boyhood Manchester City fan starring for his team.  

Foden scored a stunner and set up another goal as Premier League leaders City romped to a 4-1 victory over reigning champions Liverpool at Anfield on Sunday. 

Playing in a central role up front, Foden struggled to get into the game in the first half but thrived in the second after Guardiola had altered City's shape. 

His exquisite strike rounded off a remarkable 10-minute spell late in the second half in which the match went from 1-1 to 4-1. 

Two blunders from Alisson had gifted City their second and third goals – Ilkay Gundogan tucking in from Foden's cut back before Raheem Sterling headed home his 100th goal under Guardiola from Bernardo Silva's deft lob. 

Foden lashed in a fourth from a tight angle to wrap things up and condemn Liverpool to a third straight Anfield defeat for the first time since 1963.

Asked about the Englishman's performance, Guardiola told Sky Sports: "He's a guy who keeps the ball really well, he's really aggressive.

"But still he is so young, he doesn't understand in some positions what he has to do, so in the first half he was not in the right positions.

"We worked but he is a little bit distracted sometimes in these positions. Playing wide is more easy for him but he will learn.

"After that, the assist for the second goal and then scoring the fourth goal, we know what a huge talent he is, but he's still young and we are still hopeful that he can understand that he can improve, because in the first half he was not in the position that we needed and that's why we suffered in some moments to get the control."

Guardiola had never before tasted victory at Anfield, City's previous five visits during his tenure having returned four defeats and just one draw.

And, while the Spaniard acknowledged the difference a lack of supporters makes, he was still impressed by his players' ability to overcome in-game setbacks.

He added: "What's important is the three points. Of course I'm so proud of the guys. Anfield with people and without is completely different. It's good, especially when we miss the penalty, concede the goal.

"We react with huge personality. Raheem Sterling, phenomenal. The commitment from everyone. Three points, grateful, happy, but tomorrow feet on the grass and thinking Swansea.

"We are not one player. Gundogan started to be one of the top scorers, we have to do it as a team. We have an incredible captain. In this period, to do wins in a row is so difficult."

Thanks to their win, City sit 10 points clear of champions Liverpool and five  ahead of second-placed neighbours Manchester United at the summit of the Premier League – and with a game in hand on both. 

But Guardiola is not getting carried away as he looks ahead to a testing February fixture schedule. 

He continued: "I said before, I'm not a guy who predicts the future. In February, five points is nothing. Swansea, Tottenham, Everton, Arsenal, many tough games. Be calm and keep going. 

"In England you think February will be softer but the schedule is even tougher. One game at a time. The next one is Swansea."

Liverpool have received a triple fitness boost for their clash with Manchester City as Sadio Mane, Alisson Becker and Fabinho return from injury to start.

Fabinho is back following a three-game absence necessitated by a muscle issue, while Mane returns after a similar problem forced him to miss the Reds' last two fixtures.

Alisson, meanwhile, is back in goal after illness kept him out of the midweek defeat to Brighton and Hove Albion at Anfield.

That trio's availability accounts for three of the hosts' four changes, with 20-year-old midfielder Curtis Jones replacing the experienced James Milner the other.

Manchester City, meanwhile, make two changes to the starting XI that beat Burnley in midweek, with Pep Guardiola opting against naming a recognised striker as Gabriel Jesus drops out for Phil Foden.

At the back, Aymeric Laporte makes way, with Oleksandr Zinchenko his replacement.

Pep Guardiola praised the personality Phil Foden gave to Manchester City as they came from behind to beat Cheltenham Town 3-1 in the FA Cup, but insisted he does not have to fill Kevin De Bruyne's shoes.

Foden was instrumental as City avoided a huge shock in the fourth round on Saturday, which looked on the cards when Alfie May prodded fourth-tier Cheltenham ahead.

But the England international equalised by turning home at the far post nine minutes from time before Gabriel Jesus and Ferran Torres sealed progression to the fifth round.

City could have been out of sight by the time May put Cheltenham in front, with Guardiola's men wasteful in front of goal.

Foden played five key passes, with the fact none resulted in an assist indicative of the poor finishing displayed by City.

With De Bruyne out for up to six weeks with a hamstring injury, Guardiola was asked in his post-match media conference if Foden can help fill the void.

"Phil has to be Phil, Phil does not have to be Kevin De Bruyne," he replied. 

"Phil has to do what he is doing in terms of the bad moments when we were losing, the personality that he gave to the game.

"Phil can play in the middle, can play winger, can play in a false nine position up front. He's playing really well, again in the right moment he scored a goal."

Joao Cancelo played the cross for Foden's equaliser after coming off the bench, while fellow substitute Ilkay Gundogan pulled the ball back for Torres to tap in City's third.

Asked to explain their introductions, Guardiola said: "When you make a change you try to look for something.

"The young two players [Taylor Harwood-Bellis and Tommy Doyle] played really well but the quality of Gundogan and Joao in the final third was so important.

"Gundogan has the sense to score and with Phil and Riyad [Mahrez] in the final third we had the quality for the final pass and dribble and that's why they came in."

Manchester City eased into the fourth round of the FA Cup thanks to a Bernardo Silva-inspired 3-0 win at home to Birmingham City on Sunday.

Pep Guardiola made the somewhat surprising decision to name what was essentially his strongest possible XI, and their superior quality was telling from the start as they quickly raced into a 2-0 lead.

Silva opened the scoring with a gorgeous volley and swiftly doubled City's advantage to cap off a fine move in the 15th minute, before Phil Foden effectively killed off any hopes of a Birmingham comeback before the interval.

City were less deadly in the second period as they failed to add to their lead, but it mattered little as they had no difficulty seeing out a comfortable victory.

Aitor Karanka and Birmingham will have been braced for a difficult day after seeing the line-up chosen by Guardiola, though nothing could have prepared them for the hosts' start.

Silva displayed remarkable technique to make it 1-0 as he unleashed a stunning volley just inside the box to punish a poor clearance, picking out the top-left corner.

He soon got a second with a simple close-range finish, guiding home Kevin De Bruyne's cutback after the Belgian had been well spotted by Riyad Mahrez.

City found their stride again after something of a lull, and Foden increased the lead just past the half-hour mark, rifling into the bottom-right corner from 20 yards after being picked out by Mahrez.

The hosts withdrew De Bruyne, Joao Cancelo and Ruben Dias at half-time, with youngsters Felix Nmecha and Taylor Harwood-Bellis entering alongside John Stones.

City remained dominant and thought they had a fourth goal just past the hour, only for VAR to confirm Mahrez had strayed offside when latching on to Foden's pass.

Silva passed up the chance to complete his hat-trick as he dragged wide when the ball fell kindly for him, and that proved to be his final opportunity as City settled for a three-goal victory.

What does it mean? City emphatic but Guardiola learns little

It is fair to say, Guardiola may have surprised a few by naming such a strong starting XI and it seemingly yielded the desired result as City went into half-time 3-0 to the good.

Nevertheless, Guardiola will have learnt very little about that first-half performance given his line-up was full of first-team regulars and they were facing a side struggling in a Championship relegation battle.

A few of the kids were sent on in the second half and did their chances of further opportunities no harm, though the game had become little more than a training exercise by that point.

Foden runs Birmingham ragged

There were several City stars who produced classy displays, but Foden was arguably the most enjoyable to watch. His goal was a great strike, while he had already threatened beforehand with his other two shots. The England international also made three key passes – one of those was particularly clever, as he chested down a long ball to tee up Silva for an effort that hit the side-netting.

Gabriel Jesus frustrated

City's Brazilian striker was by no means poor here – with three shots and a couple of key passes, he was actually quite bright. But he will likely be frustrated by the fact he could not get his name on the scoreboard, particularly given one of his first-half opportunities was a one-one-one situation that he spurned.

What's next?

It is back to Premier League action on Wednesday for City, who host Brighton and Hove Albion. Birmingham continue their quest to get clear of the Championship's relegation zone three days later when they go to coach Karanka's former team Middlesbrough.
