Kane, Bellingham and Foden are unable to fit in the same lineup - is Tuchel right?
With six wins out of six, zero goals allowed and tournament placement assured before the final rounds, Three Lions boss Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
However, in the preparation for Thursday's home game against Serbia, he raised questions when he claimed that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the same team.
"At the moment, if we maintain the formation, they cannot play.
"It's possible but not with current tactics, not preserving harmony that we established and not for the structure that also includes wingers who are like specialists in their positions. We play at the moment with a six, eight, a 10 and a nine."
From certain starters to fighting for spots
Foden and Bellingham have been used in wide positions for England in the past, but Tuchel's selections imply that Marcus Rashford and Bukayo Saka are his preferred options on the wing positions respectively.
But can Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane featured in every England's seven matches at the European Championship in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 fixtures the trio have played together, England have secured 10 victories, drawn three and been defeated three times, registering 36 scores and conceding 14.
Strategic view: Versatile Foden offers solutions
Tuchel has employed a four-two-three-one setup that changes shape when England attack.
The Aston Villa player has been the main number 10 because of his impressive ball progression, shooting ability and skill in entering the penalty area when the forward retreats.
Tuchel has spoken about preferring specialist wingers. Saka and Gordon consistently operate in wide areas and can maintain possession effectively, take their full-back on, and enter the area to finish.
Supporting the attacking quartet, Tuchel employs a double pivot consisting of a holding midfielder and another with greater freedom to support offensive play.
So how could Tuchel use these three players?
Foden and Bellingham would be vying against Cole Palmer, Morgan Rogers and Eberechi Eze for the creative hub, with Kane probably featuring up front.
Foden could feature as the central striker, which in theory could permit both Bellingham and Foden to feature instead of Kane.
There is an alternative approach all three could play in this system and Tuchel hinted at it this week.
"With his club, he functions as a number eight or 10, so maybe during the next months we regard him as a central midfielder," he said.
Foden has been utilized as a flexible midfielder this season.
That has enabled him to operate from deeper areas and could position him as the advanced playmaker, next to a more defensive number six.
This would then allow Bellingham to play as the attacking midfielder and Kane as the striker.
No matter whether Tuchel chooses to configure the team like this at the World Cup, what seems encouraging is his willingness to leave big players out in the interest of team harmony.
