England's star trio can't operate simultaneously - what's the verdict?
After achieving six consecutive triumphs in six games, zero goals allowed and a World Cup spot assured before the final rounds, Three Lions boss Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
Yet, in the build-up to Thursday's Wembley encounter against Serbia, he raised questions when he stated that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the same team.
"Presently, if we maintain the formation, they cannot play.
"It's possible but not within this system, not for the balance that we established and not within the framework that comes also with wingers who are essentially experts in their positions. We presently employ with defensive, central, attacking midfielders and striker."
From guaranteed positions to competitive roles
Foden and Bellingham have been utilized out wide for England in the past, but Tuchel's selections indicate that the Manchester United forward and the Gunners' star are his preferred options on the left and right flank respectively.
So can Bellingham, Foden and Kane play together?
Gareth Southgate certainly thought so.
Bellingham, Foden and Kane featured in every England's seven games at the European Championship in Germany, where the national squad lost to Spain in the final.
In the 16 games the three have featured simultaneously, England have won 10, shared points three times and been defeated three times, registering 36 scores and conceding 14.
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 excellent dribbling, ball-striking and capacity to penetrate the area when the striker drops deep.
Tuchel has mentioned preferring specialist wingers. Saka and Gordon consistently operate in wide areas and can retain the ball skillfully, challenge defenders, and arrive in the box to score.
Supporting the attacking quartet, Tuchel employs a double pivot consisting of a disciplined defensive presence and another with greater freedom 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 in theory could allow both Bellingham and Foden to operate without the captain.
There is an alternative approach all three could feature together and Tuchel hinted at it this week.
"With his club, he plays almost like a box-to-box or creative role, so maybe during the next months we view him as a number eight," he said.
Foden has been deployed in a versatile central position this season.
That has permitted him to contribute from midfield and could position him as the advanced playmaker, paired with a defensive anchor.
This would then allow Bellingham to play as the attacking midfielder and Kane as the nine.
No matter whether Tuchel chooses to configure the team like this at the World Cup, what bodes well is his preparedness to omit established stars in the pursuit of tactical equilibrium.
