England's star trio are unable to play together - does the manager have a point?
With six wins from six matches, an unbreached defense and tournament placement assured before the final rounds, Three Lions boss Thomas Tuchel might claim he has chosen wisely throughout qualification.
Yet, in the preparation for Thursday's home game against Serbia, he initiated discussion when he said that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the equivalent formation.
"At the moment, if we maintain the formation, they cannot play.
"They can but not with current tactics, not maintaining equilibrium that we created and not in this formation that also includes wingers who are like specialists in their positions. We play at the moment with defensive, central, attacking midfielders and striker."
From automatic picks to contested places
Foden and Bellingham have been used in wide positions for England in the past, but Tuchel's selections indicate that the Manchester United forward and Bukayo Saka are his preferred options on the left and right flank respectively.
But can Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane were selected for each England's seven matches at the European Championship in Germany, where Southgate's side lost to Spain in the final.
In the 16 matches the stars have performed simultaneously, England have triumphed 10 times, tied three matches and been defeated three times, scoring 36 times and letting in 14 strikes.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has played a 4-2-3-1 system that transforms formation when England attack.
The Aston Villa player has been the main number 10 because of his strong ball-carrying, strike quality and capacity to penetrate the area when the forward retreats.
Tuchel has mentioned preferring natural flank operators. Saka and Gordon regularly feature on the wings and can hold the ball well, engage in one-on-one situations, and enter the area to finish.
In midfield behind the attackers, Tuchel utilizes two central midfielders consisting of one defensively strict player and one with more license to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be competing with Cole Palmer, Morgan Rogers and Eberechi Eze for the number 10 role, with Kane probably featuring up front.
Foden could operate as the main forward, which potentially could permit both Bellingham and Foden to feature instead of Kane.
There is a potential solution all three could coexist effectively 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 utilized as a flexible midfielder this season.
That has permitted him to contribute from midfield and could position him as the central midfielder, next to a more defensive number six.
This would then allow Bellingham to play as the number 10 and Kane as the center forward.
No matter whether Tuchel decides to set England up like this at the World Cup, what appears positive is his preparedness to omit established stars in the pursuit of tactical equilibrium.
