England's star trio can't fit in the same lineup - does the manager have a point?
Having secured six victories from six matches, zero goals allowed and tournament placement confirmed with matches remaining, national team coach Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
Nevertheless, in the build-up to Thursday's home game against Serbia, he sparked a debate when he said that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"At the moment, if we maintain the formation, they cannot play.
"It's possible but not within this system, not preserving harmony that we developed and not for the structure that incorporates wingers who are essentially experts in their positions. We presently employ with defensive, central, attacking midfielders and striker."
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 imply that the Barcelona loanee and Arsenal's winger are his first choices on the wide areas respectively.
The question remains whether Bellingham, Foden and Kane coexist in the lineup?
The previous England manager certainly thought so.
Bellingham, Foden and Kane started all of England's seven games at the European Championship in Germany, where the England team lost to Spain in the final.
In the 16 matches the stars have performed alongside each other, England have triumphed 10 times, drawn three and lost three, scoring 36 times and letting in 14 strikes.
Strategic view: Versatile Foden offers solutions
Tuchel has played a 4-2-3-1 system that changes shape when England attack.
The Aston Villa player has been the primary attacking midfielder because of his excellent dribbling, ball-striking and capacity to penetrate the area when the number nine withdraws.
Tuchel has mentioned preferring dedicated wide players. The wide attackers play out wide weekly and can maintain possession effectively, engage in one-on-one situations, and arrive in the box to score.
Supporting the attacking quartet, Tuchel utilizes two central midfielders consisting of one defensively strict player and another with greater freedom to contribute to the attack.
So how could Tuchel use these three players?
Foden and Bellingham would be battling with attacking alternatives 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 feature instead of Kane.
There is one way all three could coexist effectively and Tuchel alluded to it this week.
"At Manchester City, he plays almost like a central or attacking midfielder, so maybe during the next months we regard him as a central midfielder," he said.
Foden has been deployed in a versatile central position this season.
That has enabled him to operate from deeper areas and could categorize him as the central midfielder, next to a more defensive number six.
This would then permit Bellingham to feature as the attacking midfielder and Kane as the nine.
Regardless of if Tuchel opts to structure the side like this at the World Cup, what seems encouraging is his readiness to exclude star names in the name of balance.
