Kane, Bellingham and Foden are unable to play together - is Tuchel right?
With six wins out of six, no goals conceded and World Cup qualification secured with two group games to spare, Three Lions boss Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
Yet, in the build-up to Thursday's Wembley encounter against Serbia, he raised questions when he claimed that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"At the moment, if we maintain the formation, they are unable to feature.
"It's possible but not within this system, not for the balance that we created and not in this formation that incorporates wingers who are like specialists in their positions. We presently employ with specific numbered positions."
From certain starters to fighting for spots
Foden and Bellingham have been utilized out wide for England in the past, but Tuchel's selections indicate that Marcus Rashford and Bukayo Saka are his preferred options on the wide areas respectively.
But can Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane featured in every England's seven fixtures at last summer's tournament in Germany, where the England team lost to Spain in the final.
In the 16 games the trio have played together, England have secured 10 victories, shared points three times and suffered three losses, netting 36 goals and allowing 14 goals.
Strategic view: Versatile Foden offers solutions
Tuchel has played a 4-2-3-1 system that alters structure when England attack.
The Aston Villa player has been the primary attacking midfielder because of his impressive ball progression, ball-striking and skill in entering the penalty area when the striker drops deep.
Tuchel has mentioned preferring natural flank operators. The Arsenal and Newcastle stars play out wide weekly and can maintain possession effectively, take their full-back on, and arrive in the box to score.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of a disciplined defensive presence and a partner with attacking liberty to join the forward movement.
Potential configurations for England's stars
Foden and Bellingham would be vying against attacking alternatives for the number 10 role, with Kane likely to start up front.
Foden could play as the central striker, which potentially could permit both Bellingham and Foden to feature instead of Kane.
There is a potential solution all three could coexist effectively and Tuchel hinted at it this week.
"At Manchester City, he operates similarly to a central or attacking midfielder, so perhaps in coming months we view him as a number eight," he said.
Foden has been utilized as a flexible midfielder this season.
That has permitted him to contribute from midfield and could position him as the number eight, alongside a holding midfielder.
This would then enable Bellingham to operate as the number 10 and Kane as the nine.
Regardless of if Tuchel opts to structure the side like this at the World Cup, what seems encouraging is his willingness to leave big players out in the interest of team harmony.
