England's star trio struggle to fit in the same lineup - does the manager have a point?
After achieving six consecutive triumphs from six matches, an unbreached defense and tournament placement secured with two group games to spare, England manager Thomas Tuchel can argue he has got all of his big qualifying decisions correct.
However, in the preparation for Thursday's home game 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 identical lineup.
"Presently, if we keep the structure, they are unable to feature.
"They might but not within this system, not for the balance that we established and not for the structure that incorporates wingers who are essentially experts in their positions. We play at the moment with a six, eight, a 10 and a nine."
From guaranteed positions to competitive roles
The Manchester City and Real Madrid stars have been utilized out wide for England in the past, but the manager's choices indicate that the Manchester United forward and Bukayo Saka are his first choices on the left and right flank respectively.
The question remains whether Bellingham, Foden and Kane play together?
Former Three Lions boss apparently believed they could.
Bellingham, Foden and Kane were selected for each England's seven matches at the European Championship in Germany, where Southgate's side lost to Spain in the final.
In the 16 games the trio have played alongside each other, England have secured 10 victories, drawn three and been defeated three times, registering 36 scores 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 Aston Villa player has been the key creative force because of his impressive ball progression, ball-striking and skill in entering the penalty area when the number nine withdraws.
Tuchel has spoken about preferring dedicated wide players. Saka and Gordon play out wide weekly and can retain the ball skillfully, engage in one-on-one situations, 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 contribute to the attack.
What solutions exist for the trio?
Foden and Bellingham would be vying against attacking alternatives for the number 10 role, with Kane probably featuring up front.
Foden could play as the number nine, which in theory could enable both Bellingham and Foden to operate without the captain.
There is an alternative approach all three could feature together and Tuchel hinted at it this week.
"With his club, he operates similarly to 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 make him an option as the central midfielder, alongside a holding midfielder.
This would then permit Bellingham to feature as the attacking midfielder and Kane as the striker.
Irrespective of whether Tuchel decides to set England up like this at the international competition, what bodes well is his willingness to leave big players out in the name of balance.
