England's star trio struggle to play together - is Tuchel right?
After achieving six consecutive triumphs from six matches, an unbreached defense and tournament placement assured before the final rounds, Three Lions boss Thomas Tuchel can argue he has made the right selection choices.
Yet, in the lead-up to Thursday's domestic match against Serbia, he raised questions when he said that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"Presently, if we maintain the formation, they are unable to feature.
"It's possible but not in the structure, not preserving harmony that we created and not within the framework that incorporates wingers who are highly specialized in their positions. We play at the moment with a six, eight, a 10 and a nine."
From certain starters to fighting for spots
England's creative talents have been utilized out wide for England in the past, but Tuchel's selections indicate that Marcus Rashford and the Gunners' star are his first choices on the left and right flank respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane started all of England's seven fixtures at the European Championship in Germany, where the England team were defeated by Spain in the final.
In the 16 matches the trio have played simultaneously, England have secured 10 victories, tied three matches and lost three, scoring 36 times and allowing 14 goals.
Strategic view: Versatile Foden offers solutions
Tuchel has employed a four-two-three-one setup that changes shape when England attack.
The Aston Villa player has been the key creative force because of his impressive ball progression, strike quality and skill in entering the penalty area when the striker drops deep.
Tuchel has discussed favoring dedicated wide players. The Arsenal and Newcastle stars consistently operate in wide areas and can maintain possession effectively, engage in one-on-one situations, and appear in scoring positions.
In midfield behind the attackers, Tuchel utilizes two central midfielders consisting of one defensively strict player and a partner with attacking liberty to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be vying against Cole Palmer, Morgan Rogers and Eberechi Eze for the attacking midfield position, with Kane expected to lead up front.
Foden could play as the number nine, which theoretically could allow both Bellingham and Foden to play at Kane's expense.
There is a potential solution all three could play in this system and Tuchel suggested it this week.
"With his club, he functions as a number eight or 10, so perhaps in coming months we regard him as a central midfielder," he said.
Foden has been utilized as a flexible midfielder this season.
That has allowed him to take responsibility deeper and could position him as the number eight, next to a more defensive number six.
This would then enable Bellingham to operate as the creative force and Kane as the striker.
No matter whether Tuchel opts to structure the side like this at the World Cup, what appears positive is his willingness to leave big players out in the pursuit of tactical equilibrium.
