Three Lions' top talents struggle to operate simultaneously - what's the verdict?
After achieving six consecutive triumphs out of six, an unbreached defense and tournament placement secured with two group games to spare, England manager Thomas Tuchel could suggest he has chosen wisely throughout qualification.
However, in the build-up to Thursday's home game against Serbia, he raised questions when he said that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"At the moment, if we maintain the formation, they won't fit together.
"They might but not with current tactics, not maintaining equilibrium that we created and not for the structure that also includes wingers who are essentially experts in their positions. We currently utilize with defensive, central, attacking midfielders and striker."
From automatic picks to contested places
The Manchester City and Real Madrid stars have been utilized out wide for England in the past, but the manager's choices indicate that Marcus Rashford and the Gunners' star are his preferred options on the left and right flank respectively.
The question remains whether Bellingham, Foden and Kane play together?
Former Three Lions boss 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 were defeated by Spain in the final.
In the 16 games the three have featured simultaneously, England have secured 10 victories, drawn three and suffered three losses, registering 36 scores and letting in 14 strikes.
Tactical insight: Foden's flexibility provides alternatives
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 excellent dribbling, strike quality and ability to attack the box when the striker drops deep.
Tuchel has discussed favoring dedicated wide players. The wide attackers regularly feature on the wings and can hold the ball well, challenge defenders, and appear in scoring positions.
Behind this front four, Tuchel employs a double pivot consisting of a disciplined defensive presence and another with greater freedom to contribute to the attack.
Potential configurations for England's stars
Foden and Bellingham would be competing with Cole Palmer, Morgan Rogers and Eberechi Eze for the creative hub, with Kane expected to lead up front.
Foden could play as the main forward, which theoretically could permit both Bellingham and Foden to play at Kane's expense.
There is one way all three could coexist effectively and Tuchel hinted at it this week.
"With his club, he operates similarly to a number eight or 10, so potentially in future we regard him as a central midfielder," he said.
Foden has been deployed in a versatile central position this season.
That has allowed him to take responsibility deeper and could categorize him as the number eight, paired with a defensive anchor.
This would then allow Bellingham to play as the attacking midfielder and Kane as the striker.
Regardless of if Tuchel opts to structure the side like this at the global tournament, what seems encouraging is his willingness to leave big players out in the interest of team harmony.
