Kane, Bellingham and Foden struggle to play together - does the manager have a point?
After achieving six consecutive triumphs in six games, an unbreached defense and World Cup qualification assured before the final rounds, Three Lions boss Thomas Tuchel can argue he has chosen wisely throughout qualification.
Nevertheless, in the build-up to Thursday's home game against Serbia, he sparked a debate when he claimed that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"Presently, if we stick with the system, they won't fit together.
"It's possible but not with current tactics, not maintaining equilibrium that we established and not in this formation that also includes wingers who are essentially experts in their positions. We currently utilize with specific numbered positions."
From automatic picks to contested places
Foden and Bellingham have been used in wide positions for England in the past, but his team selections indicate that the Barcelona loanee and Arsenal's winger are his preferred options on the wide areas respectively.
So can Bellingham, Foden and Kane operate simultaneously?
The previous England manager evidently thought it possible.
Bellingham, Foden and Kane were selected for each England's seven games at the European Championship in Germany, where Southgate's side lost to Spain in the final.
In the 16 matches the trio have played together, England have secured 10 victories, tied three matches and suffered three losses, scoring 36 times and letting in 14 strikes.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has utilized a 4-2-3-1 formation that changes shape when England attack.
The young midfielder has been the key creative force because of his strong ball-carrying, ball-striking and capacity to penetrate the area when the striker drops deep.
Tuchel has spoken about preferring natural flank operators. The Arsenal and Newcastle stars play out wide weekly and can hold the ball well, challenge defenders, and arrive in the box to score.
Behind this front four, Tuchel utilizes two central midfielders consisting of a disciplined defensive presence and a partner with attacking liberty to support offensive play.
So how could Tuchel use these three players?
Foden and Bellingham would be vying against other creative midfielders for the attacking midfield position, with Kane expected to lead up front.
Foden could play as the main forward, which in theory could permit both Bellingham and Foden to play at Kane's expense.
There is a potential solution all three could play in this system and Tuchel hinted at it this week.
"At Manchester City, he functions as a central or attacking midfielder, so potentially in future we consider him as a number eight," he said.
Foden has been utilized as a flexible midfielder this season.
That has enabled him to operate from deeper areas and could make him an option as the advanced playmaker, paired with a defensive anchor.
This would then permit Bellingham to feature as the attacking midfielder and Kane as the striker.
Regardless of if Tuchel decides to set England up like this at the international competition, what bodes well is his preparedness to omit established stars in the interest of team harmony.
