Kane, Bellingham and Foden can't fit in the same lineup - is Tuchel right?
After achieving six consecutive triumphs out of six, zero goals allowed and tournament placement secured with two group games to spare, England manager Thomas Tuchel could suggest he has chosen wisely throughout qualification.
Yet, in the lead-up to Thursday's domestic match against Serbia, he initiated discussion when he claimed that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"At the moment, if we stick with the system, they are unable to feature.
"They might but not within this system, not preserving harmony that we developed and not within the framework that incorporates wingers who are essentially experts in their positions. We currently utilize with defensive, central, attacking midfielders and striker."
From certain starters to fighting for spots
The Manchester City and Real Madrid stars have been used in wide positions for England in the past, but his team selections indicate that the Barcelona loanee and Bukayo Saka are his primary selections on the wing positions respectively.
So can Bellingham, Foden and Kane operate simultaneously?
The previous England manager certainly thought so.
Bellingham, Foden and Kane were selected for each England's seven fixtures at the European Championship in Germany, where Southgate's side fell to the Spanish in the final.
In the 16 games the three have featured simultaneously, England have won 10, tied three matches and lost three, scoring 36 times and allowing 14 goals.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has utilized a 4-2-3-1 formation that alters structure when England attack.
Morgan Rogers has been the key creative force because of his impressive ball progression, strike quality and ability to attack the box when the number nine withdraws.
Tuchel has spoken about preferring specialist wingers. The wide attackers consistently operate in wide areas and can hold the ball well, take their full-back on, and arrive in the box to score.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of a disciplined defensive presence and another with greater freedom to join the forward movement.
So how could Tuchel use these three players?
Foden and Bellingham would be vying against other creative midfielders for the creative hub, with Kane probably featuring up front.
Foden could operate as the number nine, which in theory could allow both Bellingham and Foden to feature instead of Kane.
There is a potential solution all three could play in this system and Tuchel suggested it this week.
"With his club, he functions as a number eight or 10, so perhaps in coming months we consider him as a box-to-box player," 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 position him as the advanced playmaker, alongside a holding midfielder.
This would then enable Bellingham to operate as the number 10 and Kane as the nine.
Irrespective of whether Tuchel opts to structure the side like this at the global tournament, what appears positive is his preparedness to omit established stars in the interest of team harmony.
