Three Lions' top talents can't operate simultaneously - does the manager have a point?
After achieving six consecutive triumphs out of six, zero goals allowed and tournament placement confirmed with matches remaining, Three Lions boss Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
However, in the build-up to Thursday's domestic match against Serbia, he raised questions when he claimed that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the equivalent formation.
"Presently, if we keep the structure, they cannot play.
"It's possible but not within this system, not maintaining equilibrium that we developed and not within the framework that also includes wingers who are highly specialized in their positions. We play at the moment with defensive, central, attacking midfielders and striker."
From guaranteed positions to competitive roles
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 the Gunners' star are his primary selections on the wing positions respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss apparently believed they could.
Bellingham, Foden and Kane were selected for each England's seven fixtures at the European Championship in Germany, where Southgate's side fell to the Spanish in the final.
In the 16 games the three have featured alongside each other, England have won 10, shared points three times and been defeated three times, registering 36 scores and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has utilized a 4-2-3-1 formation that changes shape when England attack.
The young midfielder has been the key creative force because of his strong ball-carrying, shooting ability and ability to attack the box when the forward retreats.
Tuchel has spoken about preferring natural flank operators. The Arsenal and Newcastle stars consistently operate in wide areas and can maintain possession effectively, challenge defenders, and appear in scoring positions.
Supporting the attacking quartet, Tuchel employs a double pivot consisting of a holding midfielder and a partner with attacking liberty to contribute to the attack.
What solutions exist for the trio?
Foden and Bellingham would be battling with other creative midfielders for the attacking midfield position, with Kane expected to lead up front.
Foden could feature as the number nine, which potentially could enable both Bellingham and Foden to operate without the captain.
There is one way all three could feature together and Tuchel hinted at it this week.
"For Man City, he operates similarly to a box-to-box or creative role, so maybe during the next months we regard him as a number eight," he said.
Foden has been utilized as a flexible midfielder this season.
That has allowed him to take responsibility deeper and could categorize him as the advanced playmaker, paired with a defensive anchor.
This would then permit Bellingham to feature as the number 10 and Kane as the center forward.
No matter whether Tuchel decides to set England up like this at the global tournament, what appears positive is his willingness to leave big players out in the name of balance.
