England's star trio struggle to fit in the same lineup - is Tuchel right?
With six wins in six games, zero goals allowed and a World Cup spot secured with two group games to spare, Three Lions boss Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
However, in the build-up to Thursday's Wembley encounter against Serbia, he initiated discussion when he stated that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"Currently, if we maintain the formation, they won't fit together.
"They can but not with current tactics, not maintaining equilibrium that we developed and not in this formation that also includes wingers who are highly specialized in their positions. We presently employ with a six, eight, a 10 and a nine."
From guaranteed positions to competitive roles
Foden and Bellingham have been utilized out wide for England in the past, but his team selections suggest that the Manchester United forward and Bukayo Saka are his preferred options on the wide areas respectively.
So can Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss apparently believed they could.
Bellingham, Foden and Kane started all of England's seven matches at the European Championship in Germany, where Southgate's side lost to Spain in the final.
In the 16 games the stars have performed alongside each other, England have triumphed 10 times, shared points three times and lost three, registering 36 scores and conceding 14.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has employed a four-two-three-one setup that alters structure when England attack.
The Aston Villa player has been the main number 10 because of his strong ball-carrying, ball-striking and ability to attack the box when the forward retreats.
Tuchel has mentioned preferring dedicated wide players. The wide attackers consistently operate in wide areas and can retain the ball skillfully, challenge defenders, and appear in scoring positions.
Supporting the attacking quartet, Tuchel plays with a midfield two 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 battling with attacking alternatives for the creative hub, with Kane probably featuring up front.
Foden could play as the number nine, which potentially could permit both Bellingham and Foden to operate without the captain.
There is one way all three could feature together and Tuchel alluded to it this week.
"At Manchester City, he functions as a number eight or 10, so perhaps in coming months we regard him as a central midfielder," he said.
Foden has been utilized as a flexible midfielder this season.
That has enabled him to operate from deeper areas and could categorize him as the advanced playmaker, alongside a holding midfielder.
This would then permit Bellingham to feature as the number 10 and Kane as the striker.
Regardless of if Tuchel decides to set England up like this at the World Cup, what seems encouraging is his preparedness to omit established stars in the interest of team harmony.
