Three Lions' top talents can't play together - is Tuchel right?
After achieving six consecutive triumphs out of six, zero goals allowed and tournament placement secured with two group games to spare, Three Lions boss Thomas Tuchel can argue he has got all of his big qualifying decisions correct.
Nevertheless, in the lead-up to Thursday's Wembley encounter against Serbia, he raised questions when he said that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"Currently, if we stick with the system, they won't fit together.
"It's possible but not within this system, not preserving harmony that we created and not within the framework that also includes wingers who are like specialists in their positions. We currently utilize with a six, eight, a 10 and a nine."
From automatic picks to contested places
The Manchester City and Real Madrid stars have been deployed on the flanks for England in the past, but his team selections suggest that the Manchester United forward and the Gunners' star are his preferred options on the wing positions respectively.
But can Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane featured in every England's seven games at the European Championship in Germany, where the England team were defeated by Spain in the final.
In the 16 matches the trio have played simultaneously, England have won 10, tied three matches and lost three, scoring 36 times and allowing 14 goals.
Analysis: Foden's versatility gives Tuchel options
Tuchel has played a 4-2-3-1 system that alters structure when England attack.
The young midfielder has been the key creative force because of his excellent dribbling, strike quality and skill in entering the penalty area when the forward retreats.
Tuchel has mentioned preferring natural flank operators. The Arsenal and Newcastle stars play out wide weekly and can retain the ball skillfully, engage in one-on-one situations, and arrive in the box to score.
In midfield behind the attackers, Tuchel utilizes two central midfielders consisting of one defensively strict player and another with greater freedom to contribute to the attack.
What solutions exist for the trio?
Foden and Bellingham would be battling with Cole Palmer, Morgan Rogers and Eberechi Eze for the attacking midfield position, with Kane likely to start up front.
Foden could feature as the central striker, which potentially could enable both Bellingham and Foden to operate without the captain.
There is a potential solution all three could coexist effectively and Tuchel alluded to it this week.
"For Man City, he functions as a central or attacking midfielder, so perhaps in coming months we regard him as a number eight," he said.
Foden has been deployed in a versatile central position this season.
That has permitted him to contribute from midfield and could categorize him as the advanced playmaker, alongside a holding midfielder.
This would then enable Bellingham to operate as the attacking midfielder and Kane as the nine.
Regardless of if Tuchel decides to set England up like this at the international competition, what bodes well is his willingness to leave big players out in the pursuit of tactical equilibrium.
