England's star trio can't play together - is Tuchel right?
With six wins out of six, an unbreached defense and a World Cup spot assured before the final rounds, national team coach Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
However, in the build-up to Thursday's home game against Serbia, he sparked a debate when he claimed that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the equivalent formation.
"At the moment, if we stick with the system, they won't fit together.
"They might but not with current tactics, not for the balance that we created and not for the structure that incorporates wingers who are like specialists in their positions. We currently utilize with specific numbered positions."
From guaranteed positions to competitive roles
The Manchester City and Real Madrid stars have been utilized out wide for England in the past, but his team selections indicate that Marcus Rashford and the Gunners' star are his preferred options on the wide areas respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
Gareth Southgate evidently thought it possible.
Bellingham, Foden and Kane started all of 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 matches the trio have played alongside each other, England have triumphed 10 times, shared points three times and lost three, registering 36 scores and letting in 14 strikes.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has played a 4-2-3-1 system that changes shape when England attack.
The Aston Villa player has been the main number 10 because of his strong ball-carrying, strike quality and skill in entering the penalty area when the number nine withdraws.
Tuchel has spoken about preferring natural flank operators. The wide attackers regularly feature on the wings and can hold the ball well, challenge defenders, and appear in scoring positions.
In midfield behind the attackers, Tuchel employs a double pivot consisting of a holding midfielder and another with greater freedom to support offensive play.
So how could Tuchel use these three players?
Foden and Bellingham would be competing with Cole Palmer, Morgan Rogers and Eberechi Eze for the attacking midfield position, with Kane likely to start up front.
Foden could feature as the number nine, which theoretically could allow both Bellingham and Foden to feature instead of Kane.
There is one way all three could feature together and Tuchel hinted at it this week.
"With his club, he functions as a number eight or 10, so perhaps in coming months we view him as a box-to-box player," he said.
Foden has been utilized as a flexible midfielder this season.
That has allowed him to take responsibility deeper and could make him an option as the central midfielder, paired with a defensive anchor.
This would then allow Bellingham to play as the attacking midfielder and Kane as the nine.
Irrespective of whether Tuchel opts to structure the side like this at the international competition, what bodes well is his preparedness to omit established stars in the pursuit of tactical equilibrium.
