England's star trio can't operate simultaneously - what's the verdict?
Having secured six victories from six matches, no goals conceded and tournament placement assured before the final rounds, Three Lions boss Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
Yet, in the preparation for Thursday's Wembley encounter against Serbia, he raised questions when he said that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the equivalent formation.
"Currently, if we stick with the system, they cannot play.
"They might but not with current tactics, not maintaining equilibrium that we established and not within the framework that incorporates wingers who are highly specialized in their positions. We presently employ with specific numbered positions."
From certain starters to fighting for spots
England's creative talents have been utilized out wide for England in the past, but the manager's choices suggest that the Barcelona loanee 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 evidently thought it possible.
Bellingham, Foden and Kane were selected for each England's seven games at the European Championship in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 games the trio have played alongside each other, England have secured 10 victories, drawn three and lost three, netting 36 goals and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has played a 4-2-3-1 system that alters structure when England attack.
The young midfielder has been the main number 10 because of his excellent dribbling, strike quality and capacity to penetrate the area when the striker drops deep.
Tuchel has discussed favoring natural flank operators. Saka and Gordon consistently operate in wide areas and can hold the ball well, take their full-back on, and enter the area to finish.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of a disciplined defensive presence and another with greater freedom to join the forward movement.
Potential configurations for England's stars
Foden and Bellingham would be vying against other creative midfielders for the number 10 role, with Kane likely to start up front.
Foden could play as the main forward, which potentially could enable both Bellingham and Foden to operate without the captain.
There is one way all three could coexist effectively and Tuchel alluded to it this week.
"With his club, he plays almost like a box-to-box or creative role, so maybe during the next months we consider him as a box-to-box player," he said.
Foden has been deployed in a versatile central position 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 enable Bellingham to operate as the attacking midfielder and Kane as the nine.
Irrespective of whether Tuchel opts to structure the side like this at the international competition, what appears positive is his willingness to leave big players out in the interest of team harmony.
