England's star trio struggle to fit in the same lineup - what's the verdict?
With six wins out of six, zero goals allowed and tournament placement assured before the final rounds, England manager Thomas Tuchel could suggest he has chosen wisely throughout qualification.
Yet, in the build-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 - cannot play in the same team.
"Presently, if we keep the structure, they are unable to feature.
"It's possible but not with current tactics, not preserving harmony that we established and not within the framework that incorporates wingers who are essentially experts in their positions. We presently employ with specific numbered positions."
From guaranteed positions to competitive roles
Foden and Bellingham have been deployed on the flanks for England in the past, but the manager's choices indicate that Marcus Rashford and Bukayo Saka are his preferred options on the left and right flank respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane started all of England's seven games at last summer's tournament in Germany, where Southgate's side fell to the Spanish in the final.
In the 16 games the stars have performed together, England have triumphed 10 times, shared points three times and suffered three losses, netting 36 goals and conceding 14.
Analysis: Foden's versatility gives Tuchel options
Tuchel has utilized a 4-2-3-1 formation that changes shape when England attack.
Morgan Rogers has been the main number 10 because of his impressive ball progression, shooting ability and skill in entering the penalty area when the forward retreats.
Tuchel has mentioned preferring specialist wingers. Saka and Gordon consistently operate in wide areas and can maintain possession effectively, engage in one-on-one situations, and appear in scoring positions.
Supporting the attacking quartet, Tuchel utilizes two central midfielders consisting of a holding midfielder and a partner with attacking liberty to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be battling with attacking alternatives for the number 10 role, with Kane probably featuring up front.
Foden could feature as the main forward, which theoretically could allow both Bellingham and Foden to operate without the captain.
There is a potential solution all three could feature together and Tuchel hinted at it this week.
"With his club, he operates similarly to a number eight or 10, so potentially in future we regard 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 number eight, next to a more defensive number six.
This would then enable Bellingham to operate as the number 10 and Kane as the striker.
Irrespective of whether 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.
