England's star trio are unable to play together - does the manager have a point?
With six wins in six games, an unbreached defense and tournament placement confirmed with matches remaining, national team coach Thomas Tuchel can argue he has got all of his big qualifying decisions correct.
However, in the preparation for Thursday's Wembley encounter against Serbia, he raised questions when he said that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the identical lineup.
"Presently, if we keep the structure, they won't fit together.
"It's possible but not in the structure, not maintaining equilibrium that we developed and not in this formation that comes also with wingers who are essentially experts in their positions. We presently employ with defensive, central, attacking midfielders and striker."
From certain starters to fighting for spots
Foden and Bellingham have been used in wide positions for England in the past, but the manager's choices suggest that the Barcelona loanee and Bukayo Saka are his primary selections on the left and right flank respectively.
But can Bellingham, Foden and Kane play together?
Gareth Southgate apparently believed they could.
Bellingham, Foden and Kane featured in every England's seven matches at last summer's tournament in Germany, where the England team were defeated by Spain in the final.
In the 16 games the stars have performed simultaneously, England have triumphed 10 times, shared points three times and suffered three losses, netting 36 goals and allowing 14 goals.
Analysis: Foden's versatility gives Tuchel options
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 impressive ball progression, strike quality and skill in entering the penalty area when the forward retreats.
Tuchel has discussed favoring dedicated wide players. The wide attackers play out wide weekly and can hold the ball well, engage in one-on-one situations, and enter the area to finish.
Supporting the attacking quartet, Tuchel utilizes two central midfielders consisting of a disciplined defensive presence and a partner with attacking liberty to contribute to the attack.
Potential configurations for England's stars
Foden and Bellingham would be competing with Cole Palmer, Morgan Rogers and Eberechi Eze for the number 10 role, with Kane expected to lead up front.
Foden could feature as the number nine, which potentially could permit both Bellingham and Foden to play at Kane's expense.
There is one way all three could feature together and Tuchel hinted at it this week.
"For Man City, he plays almost like a number eight or 10, so perhaps in coming months we consider him as a central midfielder," he said.
Foden has been utilized as a flexible midfielder this season.
That has enabled him to operate from deeper areas and could position him as the advanced playmaker, alongside a holding midfielder.
This would then allow Bellingham to play as the attacking midfielder and Kane as the center forward.
Regardless of if Tuchel decides to set England up like this at the international competition, what seems encouraging is his preparedness to omit established stars in the interest of team harmony.
