Three Lions' top talents can't play together - is Tuchel right?
Having secured six victories 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 lead-up to Thursday's home game against Serbia, he raised questions when he stated that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the identical lineup.
"Currently, if we maintain the formation, they are unable to feature.
"They can but not within this system, not preserving harmony that we created and not within the framework that also includes wingers who are highly specialized in their positions. We presently employ with a six, eight, a 10 and a nine."
From automatic picks to contested places
Foden and Bellingham have been utilized out wide for England in the past, but the manager's choices indicate that the Manchester United forward and Arsenal's winger are his primary selections on the wing positions respectively.
The question remains whether Bellingham, Foden and Kane coexist in the lineup?
The previous England manager evidently thought it possible.
Bellingham, Foden and Kane started all of England's seven games at last summer's tournament in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 matches the stars have performed alongside each other, England have won 10, shared points three times and been defeated three times, registering 36 scores and conceding 14.
Analysis: Foden's versatility gives Tuchel options
Tuchel has utilized a 4-2-3-1 formation that transforms formation when England attack.
Morgan Rogers has been the key creative force because of his impressive ball progression, shooting ability and ability to attack the box when the number nine withdraws.
Tuchel has spoken about preferring natural flank operators. The Arsenal and Newcastle stars play out wide weekly and can hold the ball well, engage in one-on-one situations, and enter the area to finish.
Supporting the attacking quartet, Tuchel employs a double pivot consisting of a holding midfielder and another with greater freedom to support offensive play.
So how could Tuchel use these three players?
Foden and Bellingham would be battling with attacking alternatives for the creative hub, with Kane expected to lead up front.
Foden could play as the main forward, which potentially could enable both Bellingham and Foden to operate without the captain.
There is an alternative approach all three could feature together and Tuchel suggested it this week.
"With his club, he operates similarly to a central or attacking midfielder, so perhaps in coming months we regard 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, paired with a defensive anchor.
This would then enable Bellingham to operate as the number 10 and Kane as the center forward.
Regardless of if Tuchel chooses to configure the team like this at the global tournament, what appears positive is his preparedness to omit established stars in the interest of team harmony.
