England's star trio struggle to play together - what's the verdict?
With six wins in six games, zero goals allowed and a World Cup spot confirmed with matches remaining, Three Lions boss Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
Nevertheless, in the lead-up to Thursday's domestic match against Serbia, he raised questions when he said that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"At the moment, if we stick with the system, they are unable to feature.
"It's possible but not in the structure, not maintaining equilibrium that we established and not for the structure that incorporates wingers who are like specialists in their positions. We play at the moment with defensive, central, attacking midfielders and striker."
From automatic picks to contested places
The Manchester City and Real Madrid stars have been deployed on the flanks for England in the past, but Tuchel's selections imply that the Barcelona loanee and Arsenal's winger are his preferred options on the left and right flank respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
Former Three Lions boss evidently thought it possible.
Bellingham, Foden and Kane started all of England's seven fixtures at last summer's tournament in Germany, where Southgate's side fell to the Spanish in the final.
In the 16 matches the stars have performed alongside each other, England have secured 10 victories, drawn three and been defeated three times, registering 36 scores and letting in 14 strikes.
Strategic view: Versatile Foden offers solutions
Tuchel has employed a four-two-three-one setup that changes shape when England attack.
The Aston Villa player has been the main number 10 because of his impressive ball progression, shooting ability and ability to attack the box when the striker drops deep.
Tuchel has spoken about preferring dedicated wide players. Saka and Gordon consistently operate in wide areas and can maintain possession effectively, engage in one-on-one situations, and arrive in the box to score.
In midfield behind the attackers, Tuchel utilizes two central midfielders consisting of a holding midfielder and a partner with attacking liberty to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be competing with attacking alternatives for the attacking midfield position, with Kane likely to start 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 one way all three could coexist effectively and Tuchel suggested it this week.
"With his club, he plays almost like a number eight or 10, so maybe during the next months we regard him as a central midfielder," he said.
Foden has been utilized as a flexible midfielder this season.
That has allowed him to take responsibility deeper and could position him as the number eight, alongside a holding midfielder.
This would then allow Bellingham to play as the creative force and Kane as the nine.
No matter whether Tuchel decides to set England up like this at the global tournament, what seems encouraging is his readiness to exclude star names in the name of balance.
