Graham, London: Foden is at fault for his own success because he can play on the left side, that's where Southgate plays him, but at club level Foden plays on the right. He and Walker have a complete understanding, which is ignored at the international level.

Mark, Stockport: Thinking of Phil Foden, I wonder how many of Pep Guardiola’s players have outstanding performances for their national teams?

Anon: Foden is amazing, but it's looking more and more like he is team dependent. With Bellingham it looks like you could drop him into any team.

BBC Radio 5 Live pundit and former Manchester City player Nedum Onuoha on whether Foden can have the same impact for England as he does for his club:

He absolutely can. The key difference between himself and Bellingham is that Bellingham is more physically imposing.

Some of the things he does, Phil Foden can’t do. But in the same way, with those little bits of skill, Bellingham can’t do what Foden does. Foden’s strength is in the final third, driving with the ball, looking for a pass or with his finishes.

Bellingham can be effective in many ways, whether it is a last-ditch tackle, winning a header, competing and pushing past people or using a bit of guile.

Everyone understands that was not Phil’s best performance yesterday. The left is not his best position. But there are times when you don’t have the best game or have the same influence.

Sometimes that is down to personal things, sometimes it is the way the game flows. I am not panicking about it. There is a way for him to have a bigger impact on the game. But it is less visible at times because Phil’s impact is always going to be in the final third.

A comparison between him and Bellingham slightly misses the point. They are both supremely talented, but Foden is not going to be making a massive tackle on the edge of your own box, then bursting past people on a 40-yard run.

Jude Bellingham is one of the most complete players England has ever seen for his age, so you will see his influence on the game in far more areas.

One of the key factors is we are comparing between league football and tournament play. Manchester City are first or second in possession stats. You have longer to influence the game because your team has the ball for longer.

You can be more patient and you have more moments within a game. Spain beat Croatia at the weekend with less possession. Some of their forward players might have been frustrated because they have more possession at club level.

There are little things to clean up but the way he can play for Manchester City is very different to the way he can play for England because it is a different style of football, not just due to Gareth Southgate but the way international football is played.

I think the role on the left does not suit him. He was magnificent in the central role for Manchester City but Jude Bellingham, perfectly understandably, is the focal point of this England team so Foden has to spend much of his time in a wider position.

It will take a change of formation to sort that but I also agree with Cesc Fabregas that it is also up to Foden himself to make things happen – and I am certain he can. He is too good not to.

Southgate wants to utilise Foden, but against Serbia he once again struggled to make an impact in an area where there have been impressive reports about Anthony Gordon, a potential rival for his position, filtering out of England’s training base.

Foden's left-flank partnership with Kieran Trippier did not look a natural fit and it is something Southgate must consider before England face Denmark on Thursday.

There was no lack of endeavour, but Foden was never the constant threat he poses for City at club level. It was a low-key, peripheral performance.

No-one would ever question the talent of the English footballer of the year but accommodating him effectively is a conundrum for Southgate.
