England's star trio struggle to operate simultaneously - does the manager have a point?
Having secured six victories out of six, an unbreached defense and tournament placement secured with two group games to spare, national team coach Thomas Tuchel can argue he has chosen wisely throughout qualification.
Nevertheless, in the preparation for Thursday's domestic match against Serbia, he raised questions when he stated that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"Currently, if we keep the structure, they won't fit together.
"They might but not in the structure, 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 specific numbered positions."
From guaranteed positions to competitive roles
Foden and Bellingham have been deployed on the flanks for England in the past, but his team selections imply that the Barcelona loanee and Bukayo Saka are his preferred options on the wide areas respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
Gareth Southgate evidently thought it possible.
Bellingham, Foden and Kane were selected for each England's seven matches at last summer's tournament in Germany, where the national squad fell to the Spanish in the final.
In the 16 matches the stars have performed together, England have won 10, shared points three times and lost three, registering 36 scores and conceding 14.
Analysis: Foden's versatility gives Tuchel options
Tuchel has employed a four-two-three-one setup that alters structure when England attack.
The Aston Villa player has been the key creative force because of his impressive ball progression, shooting ability and skill in entering the penalty area when the striker drops deep.
Tuchel has spoken about preferring specialist wingers. The Arsenal and Newcastle stars consistently operate in wide areas and can maintain possession effectively, engage in one-on-one situations, and appear in scoring positions.
Supporting the attacking quartet, Tuchel plays with a midfield two consisting of a disciplined defensive presence and a partner with attacking liberty to join the forward movement.
So how could Tuchel use these three players?
Foden and Bellingham would be competing with attacking alternatives for the attacking midfield position, with Kane probably featuring up front.
Foden could operate as the number nine, which in theory could permit both Bellingham and Foden to operate without the captain.
There is a potential solution all three could play in this system and Tuchel suggested it this week.
"With his club, he plays almost like a central or attacking midfielder, so maybe during the next months we regard him as a number eight," he said.
Foden has been used in a more all-purpose midfield role this season.
That has enabled him to operate from deeper areas and could make him an option as the advanced playmaker, alongside a holding midfielder.
This would then enable Bellingham to operate as the attacking midfielder and Kane as the striker.
Regardless of if Tuchel chooses to configure the team like this at the global tournament, what seems encouraging is his willingness to leave big players out in the interest of team harmony.
