Kane, Bellingham and Foden can't operate simultaneously - is Tuchel right?
With six wins in six games, no goals conceded and tournament placement confirmed with matches remaining, national team coach Thomas Tuchel can argue he has chosen wisely throughout qualification.
Nevertheless, in the build-up to Thursday's Wembley encounter against Serbia, he raised questions when he stated that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"At the moment, if we keep the structure, they cannot play.
"It's possible but not in the structure, not preserving harmony that we created and not in this formation that incorporates wingers who are like specialists in their positions. We currently utilize with specific numbered positions."
From guaranteed positions to competitive roles
The Manchester City and Real Madrid stars have been utilized out wide for England in the past, but his team selections suggest that the Manchester United forward and Bukayo Saka are his preferred options on the wide areas respectively.
So can Bellingham, Foden and Kane play together?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane started all of England's seven fixtures at the European Championship in Germany, where Southgate's side fell to the Spanish in the final.
In the 16 matches the three have featured simultaneously, England have secured 10 victories, drawn three and lost three, scoring 36 times and allowing 14 goals.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has employed a four-two-three-one setup that changes shape when England attack.
Morgan Rogers has been the key creative force because of his impressive ball progression, strike quality and ability to attack the box when the number nine withdraws.
Tuchel has spoken about preferring dedicated wide players. The Arsenal and Newcastle stars regularly feature on the wings and can maintain possession effectively, take their full-back on, and appear in scoring positions.
Supporting the attacking quartet, Tuchel employs a double pivot consisting of a holding midfielder and one with more license to support offensive play.
So how could Tuchel use these three players?
Foden and Bellingham would be vying against attacking alternatives for the creative hub, with Kane probably featuring up front.
Foden could play as the number nine, which potentially could permit both Bellingham and Foden to feature instead of Kane.
There is one way all three could feature together and Tuchel hinted at it this week.
"With his club, he plays almost like a central or attacking midfielder, so perhaps in coming months we view him as a central midfielder," he said.
Foden has been utilized as a flexible midfielder this season.
That has permitted him to contribute from midfield and could make him an option as the advanced playmaker, paired with a defensive anchor.
This would then enable Bellingham to operate as the creative force and Kane as the nine.
Irrespective of whether Tuchel decides to set England up like this at the international competition, what bodes well is his preparedness to omit established stars in the pursuit of tactical equilibrium.
