England's star trio can't fit in the same lineup - what's the verdict?
After achieving six consecutive triumphs from six matches, no goals conceded and World Cup qualification assured before the final rounds, national team coach Thomas Tuchel can argue 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 - are unable to feature in the equivalent formation.
"Currently, if we stick with the system, they are unable to feature.
"They can but not with current tactics, not preserving harmony that we developed and not in this formation that also includes wingers who are essentially experts in their positions. We play at the moment with defensive, central, attacking midfielders and striker."
From automatic picks to contested places
England's creative talents have been used in wide positions for England in the past, but the manager's choices suggest that the Manchester United forward and the Gunners' star are his primary selections on the wide areas respectively.
But can Bellingham, Foden and Kane play together?
Former Three Lions boss apparently believed they could.
Bellingham, Foden and Kane were selected for each England's seven fixtures at the European Championship in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 fixtures the three have featured simultaneously, England have secured 10 victories, tied three matches and lost three, registering 36 scores and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has played a 4-2-3-1 system that changes shape when England attack.
The young midfielder has been the primary attacking midfielder because of his excellent dribbling, strike quality and ability to attack the box when the striker drops deep.
Tuchel has discussed favoring dedicated wide players. The Arsenal and Newcastle stars regularly feature on the wings and can retain the ball skillfully, take their full-back on, and arrive in the box to score.
Behind this front four, Tuchel plays with a midfield two consisting of a disciplined defensive presence and one with more license to join the forward movement.
So how could Tuchel use these three players?
Foden and Bellingham would be battling with other creative midfielders for the creative hub, with Kane likely to start up front.
Foden could feature as the main forward, which potentially could enable both Bellingham and Foden to feature instead of Kane.
There is an alternative approach all three could coexist effectively and Tuchel hinted at it this week.
"With his club, he functions as a number eight or 10, so maybe during the next months we view him as a number eight," he said.
Foden has been used in a more all-purpose midfield role this season.
That has allowed him to take responsibility deeper and could make him an option as the advanced playmaker, alongside a holding midfielder.
This would then enable Bellingham to operate as the creative force and Kane as the nine.
Irrespective of whether Tuchel opts to structure the side like this at the World Cup, what seems encouraging is his readiness to exclude star names in the pursuit of tactical equilibrium.
