Three Lions' top talents are unable to operate simultaneously - what's the verdict?
After achieving six consecutive triumphs from six matches, zero goals allowed and a World Cup spot secured with two group games to spare, national team coach Thomas Tuchel might claim he has got all of his big qualifying decisions correct.
Nevertheless, in the lead-up to Thursday's home game against Serbia, he initiated discussion when he stated that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the same team.
"At the moment, if we stick with the system, they are unable to feature.
"It's possible but not within this system, not preserving harmony that we established and not in this formation that comes also with 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 his team selections imply that Marcus Rashford and Arsenal's winger are his primary selections on the wing positions respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
The previous England manager evidently thought it possible.
Bellingham, Foden and Kane started all of England's seven matches at the European Championship in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 games the stars have performed simultaneously, England have won 10, drawn three and lost three, netting 36 goals and allowing 14 goals.
Analysis: Foden's versatility gives Tuchel options
Tuchel has played a 4-2-3-1 system that transforms formation when England attack.
The Aston Villa player has been the key creative force because of his strong ball-carrying, strike quality and capacity to penetrate the area when the forward retreats.
Tuchel has discussed favoring natural flank operators. The wide attackers consistently operate in wide areas and can hold the ball well, take their full-back on, and appear in scoring positions.
Behind this front four, Tuchel utilizes two central midfielders consisting of one defensively strict player and a partner with attacking liberty to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be competing with attacking alternatives for the number 10 role, with Kane likely to start up front.
Foden could operate as the number nine, which in theory could permit both Bellingham and Foden to play at Kane's expense.
There is a potential solution all three could feature together and Tuchel hinted at it this week.
"For Man City, he operates similarly to a central or attacking midfielder, so potentially in future we view him as a number eight," he said.
Foden has been deployed in a versatile central position this season.
That has permitted him to contribute from midfield and could categorize him as the number eight, alongside a holding midfielder.
This would then permit Bellingham to feature as the number 10 and Kane as the striker.
Irrespective of whether Tuchel decides to set England up like this at the World Cup, what appears positive is his preparedness to omit established stars in the interest of team harmony.
