England's star trio struggle to operate simultaneously - what's the verdict?
With six wins in six games, zero goals allowed and World Cup qualification assured before the final rounds, England manager Thomas Tuchel can argue he has got all of his big qualifying decisions correct.
Nevertheless, in the preparation for Thursday's Wembley encounter against Serbia, he initiated discussion when he claimed that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the identical lineup.
"At the moment, if we maintain the formation, they won't fit together.
"They might but not within this system, not for the balance that we developed and not within the framework that also includes wingers who are highly specialized in their positions. We currently utilize with defensive, central, attacking midfielders and striker."
From guaranteed positions to competitive roles
The Manchester City and Real Madrid stars have been used in wide positions for England in the past, but his team selections suggest that the Manchester United forward and the Gunners' star are his preferred options on the wide areas respectively.
So can Bellingham, Foden and Kane operate simultaneously?
Gareth Southgate certainly thought so.
Bellingham, Foden and Kane featured in every England's seven games at last summer's tournament in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 games the three have featured together, England have secured 10 victories, tied three matches and suffered three losses, netting 36 goals and conceding 14.
Strategic view: Versatile Foden offers solutions
Tuchel has utilized a 4-2-3-1 formation that transforms formation when England attack.
The Aston Villa player has been the key creative force because of his impressive ball progression, ball-striking and capacity to penetrate the area when the number nine withdraws.
Tuchel has spoken about preferring dedicated wide players. The wide attackers play out wide weekly and can hold the ball well, engage in one-on-one situations, and enter the area to finish.
Behind this front four, Tuchel utilizes two central midfielders consisting of a disciplined defensive presence and a partner with attacking liberty to support offensive play.
So how could Tuchel use these three players?
Foden and Bellingham would be competing with other creative midfielders for the attacking midfield position, with Kane probably featuring up front.
Foden could operate as the number nine, which theoretically could enable both Bellingham and Foden to feature instead of Kane.
There is one way all three could coexist effectively and Tuchel hinted at it this week.
"For Man City, he functions as a box-to-box or creative role, so perhaps in coming 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 allow Bellingham to play as the number 10 and Kane as the center forward.
No matter whether Tuchel chooses to configure the team like this at the global tournament, what bodes well is his willingness to leave big players out in the pursuit of tactical equilibrium.
