England's star trio are unable to play together - does the manager have a point?
After achieving six consecutive triumphs in six games, no goals conceded and a World Cup spot assured before the final rounds, Three Lions boss Thomas Tuchel can argue he has got all of his big qualifying decisions correct.
Nevertheless, in the preparation for Thursday's home game against Serbia, he raised questions when he claimed that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the identical lineup.
"At the moment, if we stick with the system, they cannot play.
"They might but not in the structure, not for the balance that we established and not in this formation that comes also with wingers who are essentially experts in their positions. We play at the moment with defensive, central, attacking midfielders and striker."
From certain starters to fighting for spots
The Manchester City and Real Madrid stars have been deployed on the flanks for England in the past, but his team selections imply that Marcus Rashford and the Gunners' star are his primary selections on the left and right flank respectively.
But can Bellingham, Foden and Kane play together?
Former Three Lions boss evidently thought it possible.
Bellingham, Foden and Kane were selected for each 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 three have featured together, England have triumphed 10 times, drawn three and been defeated three times, scoring 36 times and allowing 14 goals.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has utilized a 4-2-3-1 formation that changes shape when England attack.
Morgan Rogers has been the key creative force because of his strong ball-carrying, strike quality and skill in entering the penalty area when the forward retreats.
Tuchel has mentioned preferring specialist wingers. Saka and Gordon play out wide weekly and can retain the ball skillfully, take their full-back on, and arrive in the box to score.
Supporting the attacking quartet, Tuchel utilizes two central midfielders consisting of a holding midfielder and one with more license to contribute to the attack.
What solutions exist for the trio?
Foden and Bellingham would be vying against attacking alternatives for the number 10 role, with Kane expected to lead up front.
Foden could play as the central striker, which in theory could allow both Bellingham and Foden to play at Kane's expense.
There is one way all three could feature together and Tuchel hinted at it this week.
"At Manchester City, he functions as a central or attacking midfielder, 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 categorize him as the central midfielder, alongside a holding midfielder.
This would then permit Bellingham to feature as the creative force and Kane as the center forward.
No matter whether Tuchel chooses to configure the team like this at the global tournament, what bodes well is his readiness to exclude star names in the interest of team harmony.
