England's star trio are unable to operate simultaneously - is Tuchel right?
After achieving six consecutive triumphs in six games, zero goals allowed and World Cup qualification assured before the final rounds, national team coach Thomas Tuchel can argue he has got all of his big qualifying decisions correct.
Nevertheless, in the preparation for Thursday's Wembley encounter against Serbia, he raised questions when he stated that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the equivalent formation.
"At the moment, if we stick with the system, they won't fit together.
"It's possible but not in the structure, not maintaining equilibrium that we established and not in this formation that also includes wingers who are highly specialized in their positions. We currently utilize with a six, eight, a 10 and a nine."
From guaranteed positions to competitive roles
The Manchester City and Real Madrid stars have been utilized out wide for England in the past, but Tuchel's selections imply that the Barcelona loanee and Bukayo Saka are his primary selections on the wing positions respectively.
But can Bellingham, Foden and Kane play together?
Former Three Lions boss evidently thought it possible.
Bellingham, Foden and Kane started all of 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 fixtures the three have featured simultaneously, England have triumphed 10 times, drawn three and suffered three losses, netting 36 goals and allowing 14 goals.
Analysis: Foden's versatility gives Tuchel options
Tuchel has played a 4-2-3-1 system that changes shape when England attack.
Morgan Rogers has been the main number 10 because of his impressive ball progression, shooting ability and skill in entering the penalty area when the number nine withdraws.
Tuchel has discussed favoring natural flank operators. The Arsenal and Newcastle stars regularly feature on the wings and can retain the ball skillfully, engage in one-on-one situations, and enter the area to finish.
Behind this front four, Tuchel plays with a midfield two consisting of a disciplined defensive presence and a partner with attacking liberty to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be vying against attacking alternatives for the attacking midfield position, with Kane expected to lead up front.
Foden could play as the number nine, which in theory could enable both Bellingham and Foden to feature instead of Kane.
There is a potential solution all three could coexist effectively and Tuchel alluded to it this week.
"With his club, he plays almost like a box-to-box or creative role, so perhaps in coming months we regard him as a number eight," he said.
Foden has been utilized as a flexible midfielder this season.
That has permitted him to contribute from midfield and could make him an option as the central midfielder, paired with a defensive anchor.
This would then allow Bellingham to play as the attacking midfielder and Kane as the nine.
Regardless of if Tuchel decides to set England up like this at the global tournament, what appears positive is his readiness to exclude star names in the interest of team harmony.
