Kane, Bellingham and Foden struggle to 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, Three Lions boss Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
However, in the preparation for 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 - are unable to feature in the equivalent formation.
"At the moment, if we keep the structure, they won't fit together.
"They might but not within this system, not for the balance that we created and not for the structure that also includes wingers who are like specialists in their positions. We presently employ with a six, eight, a 10 and a nine."
From guaranteed positions to competitive roles
The Manchester City and Real Madrid stars have been used in wide positions for England in the past, but Tuchel's selections suggest that the Barcelona loanee and the Gunners' star are his preferred options on the left and right flank respectively.
So can Bellingham, Foden and Kane coexist in the lineup?
The previous England manager apparently believed they could.
Bellingham, Foden and Kane featured in every England's seven matches at the European Championship in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 fixtures the trio have played together, England have won 10, drawn three and been defeated three times, scoring 36 times and allowing 14 goals.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has utilized a 4-2-3-1 formation that transforms formation when England attack.
The young midfielder has been the primary attacking midfielder because of his strong ball-carrying, shooting ability and skill in entering the penalty area when the striker drops deep.
Tuchel has discussed favoring specialist wingers. Saka and Gordon consistently operate in wide areas and can retain the ball skillfully, engage in one-on-one situations, and appear in scoring positions.
In midfield behind the attackers, Tuchel employs a double pivot consisting of a disciplined defensive presence and another with greater freedom to contribute to the attack.
What solutions exist for the trio?
Foden and Bellingham would be battling with attacking alternatives for the attacking midfield position, with Kane likely to start up front.
Foden could operate as the number nine, which in theory could permit 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.
"At Manchester City, he operates similarly to a number eight or 10, so potentially in future we view him as a box-to-box player," he said.
Foden has been deployed in a versatile central position this season.
That has allowed him to take responsibility deeper and could make him an option as the number eight, next to a more defensive number six.
This would then enable Bellingham to operate as the creative force and Kane as the striker.
Regardless of if Tuchel chooses to configure the team like this at the global tournament, what appears positive is his preparedness to omit established stars in the pursuit of tactical equilibrium.
