Three Lions' top talents are unable to operate simultaneously - what's the verdict?
After achieving six consecutive triumphs out of six, no goals conceded 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 initiated discussion when he claimed that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"Presently, if we keep the structure, they are unable to feature.
"They might 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 specific numbered positions."
From certain starters to fighting for spots
The Manchester City and Real Madrid stars have been deployed on the flanks for England in the past, but the manager's choices indicate that the Manchester United forward and Bukayo Saka are his preferred options on the wide areas respectively.
The question remains whether Bellingham, Foden and Kane coexist in the lineup?
The previous England manager apparently believed they could.
Bellingham, Foden and Kane started all of England's seven fixtures 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 alongside each other, England have secured 10 victories, tied three matches and lost three, scoring 36 times and conceding 14.
Strategic view: Versatile Foden offers solutions
Tuchel has utilized a 4-2-3-1 formation that changes shape when England attack.
The young midfielder has been the main number 10 because of his strong ball-carrying, shooting ability and skill in entering the penalty area when the forward retreats.
Tuchel has discussed favoring specialist wingers. Saka and Gordon play out wide weekly and can hold the ball well, take their full-back on, and appear in scoring positions.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of a holding midfielder and a partner with attacking liberty to support offensive play.
Potential configurations for England's stars
Foden and Bellingham would be competing with attacking alternatives for the attacking midfield position, with Kane expected to lead up front.
Foden could operate as the central striker, which potentially could permit both Bellingham and Foden to operate without the captain.
There is an alternative approach all three could play in this system and Tuchel alluded to it this week.
"For Man City, he operates similarly to a number eight or 10, so potentially in future we view him as a central midfielder," he said.
Foden has been deployed in a versatile central position this season.
That has allowed him to take responsibility deeper and could position him as the central midfielder, alongside a holding midfielder.
This would then allow Bellingham to play as the number 10 and Kane as the striker.
Irrespective of whether Tuchel decides to set England up like this at the international competition, what seems encouraging is his willingness to leave big players out in the name of balance.
