Kane, Bellingham and Foden can't operate simultaneously - is Tuchel right?
After achieving six consecutive triumphs in six games, zero goals allowed and tournament placement assured before the final rounds, Three Lions boss Thomas Tuchel can argue he has chosen wisely throughout qualification.
Yet, in the preparation for Thursday's Wembley encounter against Serbia, he raised questions when he claimed that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"Currently, if we maintain the formation, they cannot play.
"They can but not within this system, not maintaining equilibrium that we developed and not within the framework that also includes wingers who are essentially experts in their positions. We presently employ with a six, eight, a 10 and a nine."
From guaranteed positions to competitive roles
Foden and Bellingham have been deployed on the flanks for England in the past, but Tuchel's selections suggest that the Manchester United forward and the Gunners' star are his first choices on the wide areas respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss evidently thought it possible.
Bellingham, Foden and Kane were selected for each England's seven fixtures at the European Championship in Germany, where Southgate's side lost to Spain in the final.
In the 16 games the stars have performed simultaneously, England have secured 10 victories, shared points three times and been defeated three times, netting 36 goals and allowing 14 goals.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has utilized a 4-2-3-1 formation that changes shape when England attack.
The young midfielder has been the primary attacking midfielder because of his impressive ball progression, shooting ability and capacity to penetrate the area when the striker drops deep.
Tuchel has mentioned preferring natural flank operators. The Arsenal and Newcastle stars play out wide weekly and can retain the ball skillfully, challenge defenders, and appear in scoring positions.
Behind this front four, Tuchel utilizes two central midfielders consisting of one defensively strict player and a partner with attacking liberty to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be vying against Cole Palmer, Morgan Rogers and Eberechi Eze for the creative hub, with Kane expected to lead up front.
Foden could operate as the number nine, which in theory could enable both Bellingham and Foden to play at Kane's expense.
There is a potential solution all three could feature together and Tuchel suggested it this week.
"With his club, he operates similarly to a central or attacking midfielder, so maybe during the next months we view him as a box-to-box player," he said.
Foden has been used in a more all-purpose midfield role this season.
That has permitted him to contribute from midfield and could position him as the number eight, alongside a holding midfielder.
This would then allow Bellingham to play as the number 10 and Kane as the center forward.
No matter whether Tuchel opts to structure the side like this at the international competition, what appears positive is his willingness to leave big players out in the pursuit of tactical equilibrium.
