Kane, Bellingham and Foden are unable to operate simultaneously - is Tuchel right?
With six wins from six matches, zero goals allowed and World Cup qualification secured with two group games to spare, national team coach Thomas Tuchel might claim he has chosen wisely throughout qualification.
Yet, in the lead-up to Thursday's Wembley encounter against Serbia, he raised questions when he claimed that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the equivalent formation.
"Presently, if we keep the structure, they are unable to feature.
"They might but not with current tactics, not maintaining equilibrium that we developed and not for the structure that incorporates wingers who are essentially experts in their positions. We play at the moment with specific numbered positions."
From automatic picks to contested places
Foden and Bellingham have been deployed on the flanks for England in the past, but the manager's choices imply that the Barcelona loanee and Bukayo Saka are his preferred options on the wide areas respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
The previous England manager apparently believed they could.
Bellingham, Foden and Kane were selected for each England's seven games at last summer's tournament in Germany, where Southgate's side lost to Spain in the final.
In the 16 games the three have featured together, England have won 10, shared points three times and suffered three losses, registering 36 scores and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has utilized a 4-2-3-1 formation that alters structure when England attack.
The Aston Villa player has been the key creative force because of his impressive ball progression, ball-striking and ability to attack the box 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, challenge defenders, and arrive in the box to score.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of one defensively strict player and one with more license to contribute to the attack.
What solutions exist for the trio?
Foden and Bellingham would be competing with Cole Palmer, Morgan Rogers and Eberechi Eze for the creative hub, with Kane expected to lead up front.
Foden could operate as the central striker, which potentially could enable both Bellingham and Foden to play at Kane's expense.
There is an alternative approach all three could feature together and Tuchel suggested it this week.
"For Man City, he functions as a box-to-box or creative role, so maybe during the next months we view him as a box-to-box player," he said.
Foden has been utilized as a flexible midfielder this season.
That has enabled him to operate from deeper areas and could categorize him as the number eight, next to a more defensive number six.
This would then enable Bellingham to operate as the attacking midfielder and Kane as the nine.
No matter whether Tuchel decides to set England up like this at the World Cup, what seems encouraging is his willingness to leave big players out in the pursuit of tactical equilibrium.
