England's star trio can't fit in the same lineup - is Tuchel right?
With six wins out of six, no goals conceded and a World Cup spot assured before the final rounds, Three Lions boss Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
Nevertheless, in the lead-up to Thursday's home game against Serbia, he sparked a debate when he stated that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the identical lineup.
"At the moment, if we stick with the system, they won't fit together.
"They might but not with current tactics, not for the balance that we created and not in this formation that incorporates wingers who are essentially experts in their positions. We currently utilize with specific numbered positions."
From automatic picks to contested places
Foden and Bellingham have been deployed on the flanks for England in the past, but his team selections imply that the Manchester United forward and Arsenal's winger are his primary selections on the wide areas respectively.
The question remains whether Bellingham, Foden and Kane play together?
Gareth Southgate apparently believed they could.
Bellingham, Foden and Kane started all of England's seven fixtures at the European Championship in Germany, where the national squad were defeated by Spain in the final.
In the 16 fixtures the three have featured together, England have won 10, shared points three times and been defeated three times, netting 36 goals 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 capacity to penetrate the area when the number nine withdraws.
Tuchel has mentioned preferring specialist wingers. The Arsenal and Newcastle stars consistently operate in wide areas and can hold the ball well, challenge defenders, and appear in scoring positions.
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 attacking alternatives for the creative hub, with Kane likely to start up front.
Foden could feature as the main forward, which in theory could enable both Bellingham and Foden to feature instead of Kane.
There is a potential solution all three could play in this system and Tuchel suggested it this week.
"For Man City, he plays almost like a central or attacking midfielder, so perhaps in coming months we consider 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 categorize him as the number eight, paired with a defensive anchor.
This would then allow Bellingham to play as the number 10 and Kane as the center forward.
Regardless of if Tuchel decides to set England up like this at the global tournament, what appears positive is his willingness to leave big players out in the name of balance.
