Kane, Bellingham and Foden are unable to play together - is Tuchel right?
With six wins in six games, zero goals allowed and a World Cup spot assured before the final rounds, England manager Thomas Tuchel can argue he has chosen wisely throughout qualification.
Yet, in the build-up to Thursday's Wembley encounter against Serbia, he raised questions when he stated that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"At the moment, if we keep the structure, they cannot play.
"They can but not within this system, not for the balance that we created and not within the framework that comes also with wingers who are essentially experts in their positions. We presently employ with a six, eight, a 10 and a nine."
From certain starters to fighting for spots
England's creative talents have been deployed on the flanks for England in the past, but the manager's choices imply that the Manchester United forward and Bukayo Saka are his preferred options on the wing positions respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
Gareth Southgate apparently believed they could.
Bellingham, Foden and Kane were selected for each England's seven matches at the European Championship in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 matches the stars have performed together, England have secured 10 victories, tied three matches and lost three, registering 36 scores and letting in 14 strikes.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has employed a four-two-three-one setup that alters structure when England attack.
The young midfielder has been the primary attacking midfielder because of his impressive ball progression, shooting ability and skill in entering the penalty area when the forward retreats.
Tuchel has discussed favoring natural flank operators. Saka and Gordon play out wide weekly and can retain the ball skillfully, engage in one-on-one situations, and appear in scoring positions.
Behind this front four, Tuchel employs a double pivot consisting of a disciplined defensive presence and one with more license to contribute to the attack.
So how could Tuchel use these three players?
Foden and Bellingham would be battling with attacking alternatives for the creative hub, with Kane expected to lead up front.
Foden could play as the central striker, which potentially could permit both Bellingham and Foden to operate without the captain.
There is a potential solution all three could play in this system and Tuchel suggested it this week.
"For Man City, he functions as a central or attacking midfielder, so perhaps in coming months we consider him as a box-to-box player," he said.
Foden has been used in a more all-purpose midfield role this season.
That has permitted him to contribute from midfield and could make him an option as the advanced playmaker, paired with a defensive anchor.
This would then allow Bellingham to play as the attacking midfielder and Kane as the center forward.
Regardless of if Tuchel chooses to configure the team like this at the international competition, what bodes well is his willingness to leave big players out in the pursuit of tactical equilibrium.
