Kane, Bellingham and Foden are unable to play together - is Tuchel right?
After achieving six consecutive triumphs out of six, no goals conceded and World Cup qualification assured before the final rounds, England manager Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
However, in the preparation for Thursday's home game against Serbia, he initiated discussion when he claimed that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the equivalent formation.
"Currently, if we keep the structure, they won't fit together.
"It's possible but not in the structure, not preserving harmony that we developed and not for the structure that also includes wingers who are like specialists in their positions. We play at the moment with specific numbered positions."
From guaranteed positions to competitive roles
Foden and Bellingham have been utilized out wide for England in the past, but the manager's choices suggest that Marcus Rashford and Arsenal's winger are his first choices on the left and right flank respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
Gareth Southgate evidently thought it possible.
Bellingham, Foden and Kane started all of England's seven fixtures at last summer's tournament in Germany, where the England team were defeated by Spain in the final.
In the 16 fixtures the three have featured together, England have won 10, tied three matches and lost three, scoring 36 times and allowing 14 goals.
Strategic view: Versatile Foden offers solutions
Tuchel has employed a four-two-three-one setup that changes shape when England attack.
The young midfielder has been the primary attacking midfielder because of his excellent dribbling, shooting ability and ability to attack the box when the striker drops deep.
Tuchel has mentioned preferring specialist wingers. The Arsenal and Newcastle stars regularly feature on the wings and can hold the ball well, engage in one-on-one situations, and arrive in the box to score.
Supporting the attacking quartet, Tuchel utilizes two central midfielders consisting of a holding midfielder and a partner with attacking liberty to join the forward movement.
Potential configurations for England's stars
Foden and Bellingham would be competing with other creative midfielders for the number 10 role, with Kane expected to lead up front.
Foden could operate as the main forward, which in theory could permit both Bellingham and Foden to operate without the captain.
There is an alternative approach all three could feature together and Tuchel hinted at it this week.
"With his club, he plays almost like a box-to-box or creative role, so potentially in future we view him as a number eight," he said.
Foden has been utilized as a flexible midfielder this season.
That has allowed him to take responsibility deeper and could categorize him as the number eight, alongside a holding midfielder.
This would then allow Bellingham to play as the creative force and Kane as the nine.
No matter whether Tuchel chooses to configure the team like this at the World Cup, what appears positive is his willingness to leave big players out in the interest of team harmony.
