Three Lions' top talents are unable to operate simultaneously - what's the verdict?
Having secured six victories in six games, no goals conceded and tournament placement secured with two group games to spare, England manager Thomas Tuchel can argue he has made the right selection choices.
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 - are unable to feature in the equivalent formation.
"At the moment, if we keep the structure, they won't fit together.
"They can but not with current tactics, not maintaining equilibrium that we established and not for the structure that also includes wingers who are like specialists in their positions. We presently employ with a six, eight, a 10 and a nine."
From automatic picks to contested places
The Manchester City and Real Madrid stars have been deployed on the flanks for England in the past, but his team selections suggest that the Manchester United forward and the Gunners' star are his preferred options on the wing positions respectively.
So can Bellingham, Foden and Kane operate simultaneously?
Gareth Southgate certainly thought so.
Bellingham, Foden and Kane were selected for each England's seven fixtures at the European Championship in Germany, where the England team lost to Spain in the final.
In the 16 fixtures the three have featured together, England have triumphed 10 times, shared points three times and suffered three losses, netting 36 goals and letting in 14 strikes.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has employed a four-two-three-one setup that alters structure when England attack.
The young midfielder has been the main number 10 because of his impressive ball progression, strike quality and skill in entering the penalty area when the forward retreats.
Tuchel has spoken about preferring natural flank operators. Saka and Gordon play out wide weekly and can retain the ball skillfully, take their full-back on, and appear in scoring positions.
Supporting the attacking quartet, Tuchel employs a double pivot 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 battling with other creative midfielders for the attacking midfield position, with Kane probably featuring up front.
Foden could operate as the main forward, which in theory could enable both Bellingham and Foden to play at Kane's expense.
There is one way all three could feature together and Tuchel alluded to it this week.
"For Man City, he functions as a number eight or 10, 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 central midfielder, next to a more defensive number six.
This would then permit Bellingham to feature as the creative force and Kane as the striker.
No matter whether Tuchel chooses to configure the team like this at the international competition, what appears positive is his willingness to leave big players out in the interest of team harmony.
