Kane, Bellingham and Foden can't fit in the same lineup - is Tuchel right?
After achieving six consecutive triumphs in six games, zero goals allowed and World Cup qualification assured before the final rounds, England manager Thomas Tuchel can argue he has chosen wisely throughout qualification.
Yet, 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 identical lineup.
"Currently, if we keep the structure, they are unable to feature.
"They might but not with current tactics, not maintaining equilibrium that we created and not in this formation that also includes wingers who are essentially experts in their positions. We presently employ with specific numbered positions."
From certain starters to fighting for spots
England's creative talents have been utilized out wide for England in the past, but his team selections imply that the Barcelona loanee and Arsenal's winger are his primary selections on the left and right flank respectively.
But can Bellingham, Foden and Kane coexist in the lineup?
The previous England manager certainly thought so.
Bellingham, Foden and Kane started all of England's seven fixtures 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 together, England have secured 10 victories, shared points three times and been defeated three times, netting 36 goals and conceding 14.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has employed a four-two-three-one setup that changes shape when England attack.
Morgan Rogers has been the main number 10 because of his strong ball-carrying, strike quality and ability to attack the box when the forward retreats.
Tuchel has spoken about preferring natural flank operators. Saka and Gordon regularly feature on the wings and can hold the ball well, challenge defenders, and appear in scoring positions.
Supporting the attacking quartet, Tuchel plays with a midfield two consisting of a holding midfielder and another with greater freedom to support offensive play.
What solutions exist for the trio?
Foden and Bellingham would be battling with Cole Palmer, Morgan Rogers and Eberechi Eze for the number 10 role, with Kane probably featuring up front.
Foden could feature as the main forward, which in theory could enable both Bellingham and Foden to operate without the captain.
There is a potential solution all three could feature together and Tuchel alluded to it this week.
"At Manchester City, he operates similarly to a central or attacking midfielder, so maybe during the next months we regard him as a central midfielder," he said.
Foden has been deployed in a versatile central position this season.
That has enabled him to operate from deeper areas and could position him as the advanced playmaker, paired with a defensive anchor.
This would then enable Bellingham to operate as the number 10 and Kane as the nine.
Irrespective of whether Tuchel opts to structure the side like this at the World Cup, what bodes well is his preparedness to omit established stars in the interest of team harmony.
