England's star trio are unable to play together - what's the verdict?
Having secured six victories in six games, an unbreached defense and a World Cup spot assured before the final rounds, England manager Thomas Tuchel can argue he has chosen wisely throughout qualification.
Nevertheless, in the build-up to Thursday's home game against Serbia, he raised questions when he said that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the same team.
"Presently, if we maintain the formation, they won't fit together.
"It's possible but not with current tactics, not maintaining equilibrium that we established and not in this formation that also includes wingers who are like specialists in their positions. We play at the moment with a six, eight, a 10 and a nine."
From guaranteed positions to competitive roles
England's creative talents have been utilized out wide for England in the past, but the manager's choices imply that the Manchester United forward and the Gunners' star are his first choices on the left and right flank respectively.
But can Bellingham, Foden and Kane play together?
The previous England manager 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 lost to Spain in the final.
In the 16 fixtures the trio have played simultaneously, England have secured 10 victories, shared points three times and suffered three losses, scoring 36 times and allowing 14 goals.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has played a 4-2-3-1 system that alters structure when England attack.
The young midfielder has been the key creative force because of his excellent dribbling, strike quality and ability to attack the box when the forward retreats.
Tuchel has discussed favoring dedicated wide players. Saka and Gordon play out wide weekly and can hold the ball well, challenge defenders, and appear in scoring positions.
In midfield behind the attackers, Tuchel employs a double pivot consisting of a disciplined defensive presence and one with more license to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be competing with other creative midfielders for the attacking midfield position, with Kane likely to start up front.
Foden could operate as the main forward, which theoretically could enable both Bellingham and Foden to feature instead of Kane.
There is an alternative approach all three could coexist effectively and Tuchel alluded to it this week.
"With his club, he functions as a number eight or 10, so potentially in future we consider him as a number eight," 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 center forward.
No matter whether Tuchel decides to set England up like this at the World Cup, what bodes well is his willingness to leave big players out in the interest of team harmony.
