England's star trio struggle to operate simultaneously - what's the verdict?
After achieving six consecutive triumphs out of six, an unbreached defense and tournament placement secured with two group games to spare, England manager Thomas Tuchel could suggest he has made the right selection choices.
Yet, in the lead-up to Thursday's Wembley encounter against Serbia, he raised questions when he said that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the same team.
"Currently, if we keep the structure, they cannot play.
"It's possible but not within this system, not maintaining equilibrium that we created and not in this formation that also includes wingers who are highly specialized in their positions. We presently employ with specific numbered positions."
From certain starters to fighting for spots
Foden and Bellingham have been deployed on the flanks for England in the past, but the manager's choices indicate that the Barcelona loanee and Bukayo Saka are his preferred options on the wing positions respectively.
So can Bellingham, Foden and Kane play together?
The previous England manager evidently thought it possible.
Bellingham, Foden and Kane started all of England's seven matches at the European Championship in Germany, where the England team lost to Spain in the final.
In the 16 matches the three have featured alongside each other, England have triumphed 10 times, drawn three and been defeated three times, scoring 36 times and allowing 14 goals.
Analysis: Foden's versatility gives Tuchel options
Tuchel has utilized a 4-2-3-1 formation that changes shape when England attack.
The young midfielder has been the primary attacking midfielder because of his impressive ball progression, shooting ability and skill in entering the penalty area when the number nine withdraws.
Tuchel has discussed favoring natural flank operators. Saka and Gordon play out wide weekly and can maintain possession effectively, engage in one-on-one situations, and enter the area to finish.
In midfield behind the attackers, Tuchel utilizes two central midfielders consisting of a disciplined defensive presence and a partner with attacking liberty to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be competing with other creative midfielders for the number 10 role, with Kane probably featuring up front.
Foden could operate as the main forward, which in theory could permit both Bellingham and Foden to feature instead of Kane.
There is one way all three could play in this system and Tuchel suggested it this week.
"With his club, he operates similarly to a central or attacking midfielder, so maybe during the next months we view him as a central midfielder," he said.
Foden has been deployed in a versatile central position this season.
That has allowed him to take responsibility deeper and could position him as the advanced playmaker, paired with a defensive anchor.
This would then allow Bellingham to play as the number 10 and Kane as the striker.
Regardless of if Tuchel opts to structure the side like this at the World Cup, what appears positive is his willingness to leave big players out in the pursuit of tactical equilibrium.
