England's star trio struggle to operate simultaneously - what's the verdict?
After achieving six consecutive triumphs from six matches, no goals conceded and World Cup qualification assured before the final rounds, Three Lions boss Thomas Tuchel could suggest he has made the right selection choices.
However, in the preparation for Thursday's domestic match against Serbia, he initiated discussion when he stated that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"At the moment, if we keep the structure, they are unable to feature.
"They might but not with current tactics, not maintaining equilibrium that we created and not for the structure that also includes wingers who are essentially experts in their positions. We currently utilize with a six, eight, a 10 and a nine."
From automatic picks to contested places
England's creative talents have been deployed on the flanks for England in the past, but the manager's choices imply that the Barcelona loanee and the Gunners' star are his preferred options on the wing positions respectively.
The question remains whether Bellingham, Foden and Kane coexist in the lineup?
The previous England manager certainly thought so.
Bellingham, Foden and Kane were selected for each England's seven fixtures 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 simultaneously, England have triumphed 10 times, tied three matches and lost three, registering 36 scores and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has employed a four-two-three-one setup that transforms formation when England attack.
Morgan Rogers has been the key creative force because of his strong ball-carrying, shooting ability and skill in entering the penalty area when the forward retreats.
Tuchel has discussed favoring dedicated wide players. Saka and Gordon consistently operate in wide areas and can maintain possession effectively, engage in one-on-one situations, and enter the area to finish.
Behind this front four, Tuchel utilizes two central midfielders consisting of a holding midfielder and one with more license to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be battling with Cole Palmer, Morgan Rogers and Eberechi Eze for the number 10 role, with Kane probably featuring up front.
Foden could feature as the main forward, which in theory could allow both Bellingham and Foden to play at Kane's expense.
There is a potential solution all three could play in this system 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 used in a more all-purpose midfield role this season.
That has enabled him to operate from deeper areas 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 chooses to configure the team like this at the international competition, what seems encouraging is his readiness to exclude star names in the pursuit of tactical equilibrium.
