Three Lions' top talents can't play together - is Tuchel right?
After achieving six consecutive triumphs out of six, no goals conceded and World Cup qualification assured before the final rounds, England manager Thomas Tuchel could suggest he has chosen wisely throughout qualification.
Yet, in the build-up to Thursday's domestic match against Serbia, he initiated discussion when he said that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the identical lineup.
"Currently, if we stick with the system, they cannot play.
"They might but not in the structure, not maintaining equilibrium that we created and not in this formation that also includes wingers who are like specialists in their positions. We presently employ with defensive, central, attacking midfielders and striker."
From automatic picks to contested places
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 primary selections on the wing positions respectively.
The question remains whether Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss apparently believed they could.
Bellingham, Foden and Kane started all of England's seven games at the European Championship in Germany, where Southgate's side lost to Spain in the final.
In the 16 fixtures the three have featured together, England have triumphed 10 times, drawn three and been defeated three times, netting 36 goals and allowing 14 goals.
Strategic view: Versatile Foden offers solutions
Tuchel has played a 4-2-3-1 system that alters structure when England attack.
The young midfielder has been the main number 10 because of his impressive ball progression, ball-striking and ability to attack the box when the forward retreats.
Tuchel has spoken about preferring specialist wingers. The Arsenal and Newcastle stars play out wide weekly and can hold the ball well, take their full-back on, and appear in scoring positions.
Supporting the attacking quartet, Tuchel employs a double pivot consisting of a disciplined defensive presence and one with more license to support offensive play.
Potential configurations for England's stars
Foden and Bellingham would be vying against other creative midfielders for the number 10 role, with Kane expected to lead up front.
Foden could feature as the main forward, which potentially could enable both Bellingham and Foden to play at Kane's expense.
There is a potential solution all three could play in this system and Tuchel alluded to it this week.
"At Manchester City, he plays almost like a box-to-box or creative role, so maybe during the next months we consider him as a number eight," he said.
Foden has been used in a more all-purpose midfield role this season.
That has allowed him to take responsibility deeper and could make him an option as the advanced playmaker, paired with a defensive anchor.
This would then allow Bellingham to play as the attacking midfielder and Kane as the center forward.
Regardless of if Tuchel opts to structure the side like this at the global tournament, what appears positive is his readiness to exclude star names in the name of balance.
