England's star trio struggle to operate simultaneously - is Tuchel right?
Having secured six victories from six matches, zero goals allowed and a World Cup spot secured with two group games to spare, national team coach Thomas Tuchel can argue he has chosen wisely throughout qualification.
Nevertheless, in the preparation for Thursday's Wembley encounter against Serbia, he sparked a debate when he said that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - are unable to feature in the equivalent formation.
"Currently, if we keep the structure, they are unable to feature.
"They might but not with current tactics, not maintaining equilibrium that we developed and not within the framework that incorporates wingers who are highly specialized in their positions. We currently utilize with a six, eight, a 10 and a nine."
From certain starters to fighting for spots
Foden and Bellingham have been utilized out wide for England in the past, but the manager's choices indicate that the Manchester United forward and the Gunners' star are his first choices on the wide areas respectively.
So can Bellingham, Foden and Kane operate simultaneously?
Gareth Southgate 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 fell to the Spanish in the final.
In the 16 fixtures the stars have performed alongside each other, England have won 10, drawn three and lost three, registering 36 scores and letting in 14 strikes.
Strategic view: Versatile Foden offers solutions
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 number nine withdraws.
Tuchel has discussed favoring dedicated wide players. The Arsenal and Newcastle stars regularly feature on the wings and can hold the ball well, engage in one-on-one situations, and arrive in the box to score.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of one defensively strict player and a partner with attacking liberty to contribute to the attack.
What solutions exist for the trio?
Foden and Bellingham would be vying against attacking alternatives for the attacking midfield position, with Kane likely to start up front.
Foden could play as the main forward, which potentially could permit both Bellingham and Foden to feature instead of Kane.
There is one way all three could feature together and Tuchel suggested it this week.
"For Man City, he plays almost like a box-to-box or creative role, so perhaps in coming months we regard him as a number eight," he said.
Foden has been utilized as a flexible midfielder this season.
That has permitted him to contribute from midfield and could categorize him as the central midfielder, next to a more defensive number six.
This would then enable Bellingham to operate as the creative force and Kane as the nine.
Irrespective of whether Tuchel chooses to configure the team like this at the global tournament, what bodes well is his willingness to leave big players out in the pursuit of tactical equilibrium.
