England's star trio can't play together - what's the verdict?
With six wins in six games, an unbreached defense and World Cup qualification confirmed with matches remaining, England manager Thomas Tuchel can argue he has made the right selection choices.
Nevertheless, in the lead-up to Thursday's domestic match against Serbia, he initiated discussion when he said that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"Currently, if we stick with the system, they are unable to feature.
"It's possible but not in the structure, not maintaining equilibrium that we created and not for the structure that also includes wingers who are highly specialized 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 suggest that Marcus Rashford and Arsenal's winger are his preferred options on the wing positions respectively.
So can Bellingham, Foden and Kane coexist in the lineup?
The previous England manager evidently thought it possible.
Bellingham, Foden and Kane started all of England's seven fixtures at last summer's tournament in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 fixtures the stars have performed alongside each other, England have triumphed 10 times, shared points three times and lost three, netting 36 goals and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has utilized a 4-2-3-1 formation that transforms formation when England attack.
The Aston Villa player has been the primary attacking midfielder because of his strong ball-carrying, ball-striking and skill in entering the penalty area when the number nine withdraws.
Tuchel has discussed favoring specialist wingers. The Arsenal and Newcastle stars regularly feature on the wings and can maintain possession effectively, engage in one-on-one situations, and appear in scoring positions.
Behind this front four, Tuchel utilizes two central midfielders consisting of a disciplined defensive presence and another with greater freedom to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be battling with Cole Palmer, Morgan Rogers and Eberechi Eze for the attacking midfield position, with Kane probably featuring up front.
Foden could play as the central striker, which theoretically could allow both Bellingham and Foden to operate without the captain.
There is an alternative approach all three could feature together and Tuchel suggested it this week.
"At Manchester City, he functions as a central or attacking midfielder, so potentially in future we consider him as a number eight," he said.
Foden has been deployed in a versatile central position this season.
That has allowed him to take responsibility deeper and could categorize him as the number eight, next to a more defensive number six.
This would then allow Bellingham to play as the attacking midfielder and Kane as the nine.
Regardless of if Tuchel chooses to configure the team like this at the international competition, what appears positive is his willingness to leave big players out in the pursuit of tactical equilibrium.
