Three Lions' top talents can't operate simultaneously - does the manager have a point?
Having secured six victories out of six, zero goals allowed and a World Cup spot confirmed with matches remaining, Three Lions boss Thomas Tuchel might claim he has made the right selection choices.
However, in the lead-up to Thursday's Wembley encounter against Serbia, he initiated discussion when he said that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the same team.
"Currently, if we maintain the formation, they are unable to feature.
"It's possible but not within this system, not maintaining equilibrium that we established and not within the framework that incorporates wingers who are highly specialized in their positions. We presently employ with specific numbered positions."
From automatic picks to contested places
The Manchester City and Real Madrid stars have been deployed on the flanks for England in the past, but the manager's choices indicate that the Barcelona loanee and the Gunners' star are his first choices on the wing positions respectively.
So can Bellingham, Foden and Kane play together?
Former Three Lions boss certainly thought so.
Bellingham, Foden and Kane were selected for each 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 matches the trio have played alongside each other, England have won 10, tied three matches and been defeated three times, scoring 36 times and conceding 14.
Strategic view: Versatile Foden offers solutions
Tuchel has played a 4-2-3-1 system that changes shape when England attack.
Morgan Rogers has been the main number 10 because of his strong ball-carrying, ball-striking and ability to attack the box when the number nine withdraws.
Tuchel has discussed favoring natural flank operators. Saka and Gordon regularly feature on the wings and can maintain possession effectively, take their full-back on, and enter the area to finish.
Behind this front four, Tuchel employs a double pivot 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 other creative midfielders for the attacking midfield position, with Kane probably featuring up front.
Foden could play as the central striker, which theoretically could enable both Bellingham and Foden to feature instead of Kane.
There is an alternative approach all three could feature together and Tuchel suggested it this week.
"For Man City, he operates similarly to a box-to-box or creative role, so potentially in future we consider him as a central midfielder," he said.
Foden has been deployed in a versatile central position this season.
That has permitted him to contribute from midfield and could position him as the number eight, alongside a holding midfielder.
This would then allow Bellingham to play 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 willingness to leave big players out in the interest of team harmony.
