Three Lions' top talents are unable to play together - what's the verdict?
Having secured six victories out of six, no goals conceded and a World Cup spot secured with two group games to spare, Three Lions boss Thomas Tuchel can argue he has chosen wisely throughout qualification.
Nevertheless, in the lead-up to Thursday's home game against Serbia, he raised questions when he claimed that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the same team.
"Currently, if we maintain the formation, they won't fit together.
"They might but not within this system, 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 defensive, central, attacking midfielders and striker."
From certain starters to fighting for spots
The Manchester City and Real Madrid stars have been deployed on the flanks for England in the past, but the manager's choices suggest that the Manchester United forward and Arsenal's winger are his primary selections on the wide areas respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
Former Three Lions boss evidently thought it possible.
Bellingham, Foden and Kane were selected for each England's seven matches at last summer's tournament in Germany, where Southgate's side lost to Spain in the final.
In the 16 fixtures the stars have performed together, England have triumphed 10 times, drawn three and lost three, scoring 36 times and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has utilized a 4-2-3-1 formation that alters structure when England attack.
The young midfielder has been the main number 10 because of his excellent dribbling, ball-striking and skill in entering the penalty area when the striker drops deep.
Tuchel has spoken about preferring dedicated wide players. The Arsenal and Newcastle stars play out wide weekly and can hold the ball well, engage in one-on-one situations, and arrive in the box to score.
Supporting the attacking quartet, Tuchel plays with a midfield two consisting of a disciplined defensive presence and another with greater freedom 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 number 10 role, with Kane probably featuring up front.
Foden could operate as the main forward, which theoretically could allow both Bellingham and Foden to feature instead of Kane.
There is one way all three could feature together and Tuchel alluded to it this week.
"At Manchester City, he functions as a central or attacking midfielder, so perhaps in coming months we view him as a central midfielder," he said.
Foden has been used in a more all-purpose midfield role this season.
That has permitted him to contribute from midfield and could make him an option as the number eight, next to a more defensive number six.
This would then allow Bellingham to play as the number 10 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 preparedness to omit established stars in the name of balance.
