England's star trio are unable to operate simultaneously - is Tuchel right?
After achieving six consecutive triumphs from six matches, no goals conceded and tournament placement confirmed with matches remaining, national team coach Thomas Tuchel could suggest he has chosen wisely throughout qualification.
However, in the build-up to Thursday's domestic match against Serbia, he initiated discussion when he stated that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the same team.
"At the moment, if we maintain the formation, they are unable to feature.
"They can but not with current tactics, not for the balance that we established and not in this formation that also includes wingers who are like specialists in their positions. We currently utilize with defensive, central, attacking midfielders and striker."
From automatic picks to contested places
England's creative talents have been utilized out wide for England in the past, but the manager's choices imply that the Barcelona loanee and Arsenal's winger are his primary selections on the wing positions respectively.
So can Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss evidently thought it possible.
Bellingham, Foden and Kane featured in every England's seven matches at last summer's tournament in Germany, where Southgate's side fell to the Spanish in the final.
In the 16 fixtures the trio have played together, England have triumphed 10 times, tied three matches and lost three, registering 36 scores and conceding 14.
Strategic view: Versatile Foden offers solutions
Tuchel has employed a four-two-three-one setup that alters structure when England attack.
The young midfielder has been the primary attacking midfielder because of his impressive ball progression, strike quality and skill in entering the penalty area when the number nine withdraws.
Tuchel has spoken about preferring specialist wingers. Saka and Gordon consistently operate in wide areas and can retain the ball skillfully, engage in one-on-one situations, and arrive in the box to score.
Behind this front four, Tuchel plays with a midfield two consisting of a holding midfielder and one with more license to contribute to the attack.
What solutions exist for the trio?
Foden and Bellingham would be battling with other creative midfielders for the number 10 role, with Kane expected to lead up front.
Foden could play as the central striker, which potentially could permit both Bellingham and Foden to operate without the captain.
There is one way all three could play in this system and Tuchel hinted at it this week.
"With his club, he operates similarly to a central or attacking midfielder, so potentially in future we regard him as a central midfielder," he said.
Foden has been utilized as a flexible midfielder this season.
That has enabled him to operate from deeper areas and could categorize him as the number eight, alongside a holding midfielder.
This would then enable Bellingham to operate as the creative force and Kane as the nine.
No matter whether Tuchel chooses to configure the team like this at the global tournament, what appears positive is his readiness to exclude star names in the name of balance.
