England's star trio struggle to operate simultaneously - does the manager have a point?
Having secured six victories in six games, no goals conceded and a World Cup spot confirmed with matches remaining, Three Lions boss Thomas Tuchel can argue he has got all of his big qualifying decisions correct.
Yet, in the build-up to Thursday's domestic match against Serbia, he initiated discussion when he claimed that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the identical lineup.
"At the moment, if we maintain the formation, they won't fit together.
"They can but not within this system, not for the balance that we developed and not for the structure that comes also with wingers who are highly specialized in their positions. We currently utilize with a six, eight, a 10 and a nine."
From automatic picks to contested places
Foden and Bellingham have been used in wide positions for England in the past, but his team selections indicate that the Manchester United forward and Arsenal's winger are his first choices on the wing positions respectively.
So can Bellingham, Foden and Kane play together?
Gareth Southgate evidently thought it possible.
Bellingham, Foden and Kane were selected for each England's seven fixtures at the European Championship in Germany, where Southgate's side lost to Spain in the final.
In the 16 games the trio have played simultaneously, England have won 10, shared points three times and lost three, 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 changes shape when England attack.
Morgan Rogers has been the primary attacking midfielder because of his excellent dribbling, ball-striking and capacity to penetrate the area when the striker drops deep.
Tuchel has discussed favoring natural flank operators. The Arsenal and Newcastle stars consistently operate in wide areas and can retain the ball skillfully, take their full-back on, and enter the area to finish.
In midfield behind the attackers, Tuchel utilizes two central midfielders consisting of one defensively strict player and another with greater freedom to join the forward movement.
So how could Tuchel use these three players?
Foden and Bellingham would be vying against other creative midfielders for the number 10 role, with Kane likely to start up front.
Foden could feature as the central striker, which potentially 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 hinted at it this week.
"With his club, he functions as a central or attacking midfielder, so potentially in future we regard 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 categorize him as the number eight, paired with a defensive anchor.
This would then allow Bellingham to play as the creative force and Kane as the center forward.
No matter whether Tuchel chooses to configure the team like this at the global tournament, what appears positive is his preparedness to omit established stars in the name of balance.
