Three Lions' top talents can't play together - does the manager have a point?
After achieving six consecutive triumphs out of six, zero goals allowed and World Cup qualification confirmed with matches remaining, national team coach Thomas Tuchel might claim he has chosen wisely throughout qualification.
However, 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 maintain the formation, they won't fit together.
"They might but not within this system, not maintaining equilibrium that we established and not for the structure that comes also with wingers who are essentially experts in their positions. We presently employ with a six, eight, a 10 and a nine."
From automatic picks to contested places
The Manchester City and Real Madrid stars have been used in wide positions for England in the past, but his team selections indicate that Marcus Rashford and the Gunners' star are his primary selections on the wide areas respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
Former Three Lions boss apparently believed they could.
Bellingham, Foden and Kane were selected for each England's seven fixtures at last summer's tournament in Germany, where Southgate's side lost to Spain in the final.
In the 16 matches the stars have performed alongside each other, England have triumphed 10 times, tied three matches and been defeated three times, netting 36 goals and conceding 14.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has played a 4-2-3-1 system that alters structure when England attack.
Morgan Rogers has been the main number 10 because of his impressive ball progression, ball-striking and capacity to penetrate the area when the forward retreats.
Tuchel has mentioned preferring natural flank operators. The Arsenal and Newcastle stars regularly feature on the wings and can hold the ball well, 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 another with greater freedom to contribute to the attack.
Potential configurations for England's stars
Foden and Bellingham would be battling with other creative midfielders for the attacking midfield position, with Kane likely to start up front.
Foden could feature as the main forward, which theoretically could permit both Bellingham and Foden to operate without the captain.
There is a potential solution all three could coexist effectively and Tuchel suggested it this week.
"At Manchester City, he functions as a central or attacking midfielder, so potentially in future we regard him as a central midfielder," he said.
Foden has been used in a more all-purpose midfield role this season.
That has enabled him to operate from deeper areas and could make him an option as the central midfielder, paired with a defensive anchor.
This would then enable Bellingham to operate as the creative force and Kane as the striker.
Regardless of if Tuchel opts to structure the side like this at the global tournament, what seems encouraging is his willingness to leave big players out in the name of balance.
