England's star trio struggle to operate simultaneously - what's the verdict?
Having secured six victories from six matches, zero goals allowed and World Cup qualification secured with two group games to spare, England manager Thomas Tuchel can argue he has got all of his big qualifying decisions correct.
Yet, in the preparation for Thursday's domestic match against Serbia, he raised questions when he claimed that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the same team.
"Presently, if we maintain the formation, they won't fit together.
"They might but not within this system, not for the balance that we established and not within the framework that also includes wingers who are essentially experts in their positions. We presently employ with specific numbered positions."
From automatic picks to contested places
The Manchester City and Real Madrid stars have been deployed on the flanks for England in the past, but Tuchel's selections imply that the Manchester United forward and Bukayo Saka are his preferred options on the wing positions respectively.
So can Bellingham, Foden and Kane operate simultaneously?
Gareth Southgate apparently believed they could.
Bellingham, Foden and Kane featured in every England's seven games at last summer's tournament in Germany, where Southgate's side fell to the Spanish in the final.
In the 16 games the three have featured simultaneously, England have won 10, shared points three times and lost three, scoring 36 times and letting in 14 strikes.
Tactical insight: Foden's flexibility provides alternatives
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 capacity to penetrate the area when the number nine withdraws.
Tuchel has spoken about preferring specialist wingers. Saka and Gordon consistently operate in wide areas and can retain the ball skillfully, take their full-back on, and enter the area to finish.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of one defensively strict player and one with more license to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be battling with attacking alternatives for the number 10 role, with Kane probably featuring up front.
Foden could play as the main forward, which potentially could permit both Bellingham and Foden to feature instead of Kane.
There is a potential solution all three could feature together and Tuchel suggested it this week.
"At Manchester City, he plays almost like a box-to-box or creative role, so potentially in future we view him as a number eight," he said.
Foden has been utilized as a flexible midfielder this season.
That has enabled him to operate from deeper areas and could position him as the central midfielder, paired with a defensive anchor.
This would then permit Bellingham to feature as the creative force and Kane as the nine.
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.
