Three Lions' top talents are unable to operate simultaneously - what's the verdict?
Having secured six victories from six matches, zero goals allowed and tournament placement secured with two group games to spare, national team coach Thomas Tuchel could suggest he has made the right selection choices.
However, in the lead-up to Thursday's Wembley encounter against Serbia, he raised questions when he said that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the equivalent formation.
"At the moment, if we keep the structure, they cannot play.
"They can but not in the structure, not maintaining equilibrium that we developed and not for the structure that comes also with wingers who are highly specialized in their positions. We presently employ with a six, eight, a 10 and a nine."
From automatic picks to contested places
Foden and Bellingham have been deployed on the flanks for England in the past, but Tuchel's selections suggest that the Barcelona loanee and the Gunners' star are his first choices on the wing positions respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
The previous England manager evidently thought it possible.
Bellingham, Foden and Kane started all of England's seven matches at last summer's tournament in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 matches the trio have played together, England have secured 10 victories, tied three matches and been defeated three times, registering 36 scores 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 primary attacking midfielder because of his strong ball-carrying, strike quality and ability to attack the box when the number nine withdraws.
Tuchel has discussed favoring specialist wingers. The Arsenal and Newcastle stars play out wide weekly and can maintain possession effectively, challenge defenders, and enter the area to finish.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of a holding midfielder and another with greater freedom to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be competing with attacking alternatives for the creative hub, with Kane probably featuring up front.
Foden could play as the main forward, which in theory could enable both Bellingham and Foden to play at Kane's expense.
There is one way all three could coexist effectively and Tuchel hinted at it this week.
"At Manchester City, he plays almost like a central or attacking midfielder, so potentially in future we consider him as a central midfielder," 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 central midfielder, alongside a holding midfielder.
This would then enable Bellingham to operate as the attacking midfielder and Kane as the center forward.
No matter whether Tuchel chooses to configure the team like this at the global tournament, what seems encouraging is his preparedness to omit established stars in the pursuit of tactical equilibrium.
