England's star trio struggle to operate simultaneously - does the manager have a point?
Having secured six victories from six matches, zero goals allowed and tournament placement assured before the final rounds, Three Lions boss Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
Nevertheless, in the preparation for Thursday's domestic match against Serbia, he sparked a debate when he said that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the identical lineup.
"Presently, if we maintain the formation, they cannot play.
"It's possible but not in the structure, not maintaining equilibrium that we developed and not within the framework that incorporates wingers who are like specialists in their positions. We play at the moment with specific numbered positions."
From guaranteed positions to competitive roles
The Manchester City and Real Madrid stars have been utilized out wide for England in the past, but his team selections imply that Marcus Rashford and Arsenal's winger are his preferred options on the wide areas respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
Gareth Southgate 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 lost to Spain in the final.
In the 16 games the trio have played together, England have won 10, shared points three times and been defeated three times, netting 36 goals and letting in 14 strikes.
Strategic view: Versatile Foden offers solutions
Tuchel has employed a four-two-three-one setup that transforms formation when England attack.
The Aston Villa player has been the main number 10 because of his impressive ball progression, strike quality and ability to attack the box when the number nine withdraws.
Tuchel has spoken about preferring specialist wingers. The wide attackers regularly feature on the wings and can hold the ball well, take their full-back on, and appear in scoring positions.
Supporting the attacking quartet, Tuchel plays with a midfield two consisting of one defensively strict player and one with more license to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be competing with other creative midfielders for the number 10 role, with Kane likely to start up front.
Foden could play as the main forward, which potentially could permit both Bellingham and Foden to play at Kane's expense.
There is one way all three could coexist effectively and Tuchel alluded to it this week.
"At Manchester City, he operates similarly to a box-to-box or creative role, so potentially in future we view him as a central midfielder," he said.
Foden has been utilized as a flexible midfielder this season.
That has enabled him to operate from deeper areas and could position him as the number eight, paired with a defensive anchor.
This would then permit Bellingham to feature as the attacking midfielder and Kane as the center forward.
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.
