Kane, Bellingham and Foden can't operate simultaneously - what's the verdict?
Having secured six victories from six matches, no goals conceded and World Cup qualification confirmed with matches remaining, England manager Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
However, in the build-up to Thursday's Wembley encounter against Serbia, he raised questions when he stated that three of the nation's top talents - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the identical lineup.
"Presently, if we keep the structure, they are unable to feature.
"They might but not in the structure, not maintaining equilibrium that we created and not within the framework that comes also with wingers who are essentially experts in their positions. We play at the moment with a six, eight, a 10 and a nine."
From certain starters to fighting for spots
Foden and Bellingham have been deployed on the flanks for England in the past, but Tuchel's selections imply that the Barcelona loanee and the Gunners' star are his primary selections on the left and right flank respectively.
But can Bellingham, Foden and Kane operate simultaneously?
The previous England manager apparently believed they could.
Bellingham, Foden and Kane started all of England's seven games at the European Championship in Germany, where the national squad were defeated by Spain in the final.
In the 16 fixtures the trio have played alongside each other, England have won 10, shared points three times and suffered three losses, scoring 36 times and letting in 14 strikes.
Analysis: Foden's versatility gives Tuchel options
Tuchel has utilized a 4-2-3-1 formation that alters structure when England attack.
The Aston Villa player has been the key creative force because of his excellent dribbling, strike quality and ability to attack the box when the striker drops deep.
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.
Supporting the attacking quartet, Tuchel utilizes two central midfielders consisting of one defensively strict player and a partner with attacking liberty to support offensive play.
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 feature instead of Kane.
There is one way all three could coexist effectively and Tuchel hinted at it this week.
"For Man City, he operates similarly to a number eight or 10, so potentially in future we regard him as a number eight," he said.
Foden has been utilized as a flexible midfielder this season.
That has allowed him to take responsibility deeper and could categorize him as the advanced playmaker, next to a more defensive number six.
This would then allow Bellingham to play as the attacking midfielder and Kane as the center forward.
No matter whether Tuchel chooses to configure the team like this at the World Cup, what appears positive is his preparedness to omit established stars in the pursuit of tactical equilibrium.
