England's star trio struggle to play together - what's the verdict?
After achieving six consecutive triumphs out of six, an unbreached defense and World Cup qualification confirmed with matches remaining, England manager Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
Nevertheless, in the build-up to Thursday's domestic match against Serbia, he initiated discussion when he stated that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the equivalent formation.
"Currently, if we maintain the formation, they are unable to feature.
"They might but not in the structure, not preserving harmony that we created and not within the framework that also includes wingers who are like specialists in their positions. We play at the moment with a six, eight, a 10 and a nine."
From certain starters to fighting for spots
Foden and Bellingham have been utilized out wide for England in the past, but his team selections imply that the Manchester United forward and Bukayo Saka are his primary selections on the wide areas respectively.
So can Bellingham, Foden and Kane play together?
Former Three Lions boss evidently thought it possible.
Bellingham, Foden and Kane featured in every 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 triumphed 10 times, tied three matches and suffered three losses, registering 36 scores and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has played a 4-2-3-1 system that transforms formation when England attack.
Morgan Rogers has been the main number 10 because of his excellent dribbling, ball-striking and ability to attack the box when the striker drops deep.
Tuchel has discussed favoring dedicated wide players. The wide attackers consistently operate in wide areas and can maintain possession effectively, engage in one-on-one situations, and appear in scoring positions.
Supporting the attacking quartet, Tuchel utilizes two central midfielders consisting of one defensively strict player and another with greater freedom to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be vying against Cole Palmer, Morgan Rogers and Eberechi Eze for the number 10 role, with Kane likely to start up front.
Foden could operate as the number nine, which in theory could enable both Bellingham and Foden to feature instead of Kane.
There is an alternative approach all three could coexist effectively and Tuchel alluded to it this week.
"At Manchester City, he functions as a number eight or 10, so potentially in future we regard him as a number eight," he said.
Foden has been deployed in a versatile central position this season.
That has enabled him to operate from deeper areas and could categorize him as the number eight, alongside a holding midfielder.
This would then enable Bellingham to operate as the creative force and Kane as the center forward.
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 pursuit of tactical equilibrium.
