Three Lions' top talents are unable to operate simultaneously - what's the verdict?
After achieving six consecutive triumphs out of six, an unbreached defense and tournament placement confirmed with matches remaining, England manager Thomas Tuchel could suggest he has chosen wisely throughout qualification.
However, in the lead-up to Thursday's Wembley encounter against Serbia, he initiated discussion when he stated that three of the country's best players - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the equivalent formation.
"Presently, if we keep the structure, they won't fit together.
"They might but not within this system, not maintaining equilibrium that we developed and not for the structure that comes also with wingers who are highly specialized in their positions. We presently employ with defensive, central, attacking midfielders and striker."
From certain starters to fighting for spots
England's creative talents have been used in wide positions for England in the past, but his team selections imply that Marcus Rashford and the Gunners' star are his first choices on the wing positions respectively.
The question remains whether Bellingham, Foden and Kane coexist in the lineup?
The previous England manager certainly thought so.
Bellingham, Foden and Kane featured in every England's seven matches at the European Championship in Germany, where Southgate's side were defeated by Spain in the final.
In the 16 games the trio have played simultaneously, England have triumphed 10 times, shared points three times and been defeated three times, scoring 36 times and allowing 14 goals.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has employed a four-two-three-one setup that transforms formation when England attack.
The young midfielder has been the primary attacking midfielder because of his strong ball-carrying, shooting ability and skill in entering the penalty area when the forward retreats.
Tuchel has discussed favoring natural flank operators. The wide attackers consistently operate in wide areas and can hold the ball well, take their full-back on, and appear in scoring positions.
Behind this front four, Tuchel utilizes two central midfielders consisting of a disciplined defensive presence and another with greater freedom to contribute to the attack.
Potential configurations for England's stars
Foden and Bellingham would be vying against other creative midfielders for the creative hub, with Kane likely to start up front.
Foden could feature as the number nine, which theoretically could permit both Bellingham and Foden to feature instead of Kane.
There is one way all three could play in this system and Tuchel suggested it this week.
"At Manchester City, he plays almost like a box-to-box or creative role, so perhaps in coming months we regard him as a box-to-box player," he said.
Foden has been used in a more all-purpose midfield role this season.
That has enabled him to operate from deeper areas and could position him as the number eight, alongside a holding midfielder.
This would then permit Bellingham to feature as the attacking midfielder and Kane as the striker.
Irrespective of whether Tuchel chooses to configure the team like this at the global tournament, what seems encouraging is his readiness to exclude star names in the interest of team harmony.
