England's star trio are unable to play together - is Tuchel right?
After achieving six consecutive triumphs in six games, zero goals allowed and tournament placement confirmed with matches remaining, England manager Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
However, in the build-up to Thursday's home game against Serbia, he sparked a debate when he stated that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"Currently, if we keep the structure, they won't fit together.
"They might but not in the structure, not for the balance that we created and not in this formation that incorporates wingers who are essentially experts in their positions. We presently employ with defensive, central, attacking midfielders and striker."
From certain starters to fighting for spots
England's creative talents have been used in wide positions for England in the past, but the manager's choices indicate that Marcus Rashford and the Gunners' star are his preferred options on the left and right flank respectively.
So can Bellingham, Foden and Kane operate simultaneously?
The previous England manager apparently believed they could.
Bellingham, Foden and Kane featured in every England's seven matches at last summer's tournament in Germany, where Southgate's side lost to Spain in the final.
In the 16 matches the three have featured simultaneously, England have triumphed 10 times, drawn three and been defeated three times, registering 36 scores and conceding 14.
Analysis: Foden's versatility gives Tuchel options
Tuchel has employed a four-two-three-one setup that changes shape when England attack.
Morgan Rogers has been the key creative force because of his impressive ball progression, ball-striking and capacity to penetrate the area when the forward retreats.
Tuchel has spoken about preferring specialist wingers. Saka and Gordon play out wide weekly and can maintain possession effectively, challenge defenders, and enter the area to finish.
In midfield behind the attackers, Tuchel employs a double pivot consisting of a holding midfielder and one with more license to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be competing with attacking alternatives for the attacking midfield position, with Kane probably featuring up front.
Foden could operate as the central striker, which potentially could allow both Bellingham and Foden to operate without the captain.
There is a potential solution all three could coexist effectively and Tuchel hinted at it this week.
"With his club, he operates similarly to a box-to-box or creative role, so potentially in future we view him as a number eight," he said.
Foden has been used in a more all-purpose midfield role this season.
That has allowed him to take responsibility deeper and could categorize him as the advanced playmaker, next to a more defensive number six.
This would then permit Bellingham to feature as the creative force and Kane as the striker.
Irrespective of whether Tuchel opts to structure the side like this at the international competition, what bodes well is his preparedness to omit established stars in the name of balance.
