England's star trio struggle to operate simultaneously - what's the verdict?
After achieving six consecutive triumphs from six matches, zero goals allowed and a World Cup spot secured with two group games to spare, national team coach Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
Yet, in the build-up to Thursday's Wembley encounter against Serbia, he sparked a debate when he claimed that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - cannot play in the same team.
"Currently, if we stick with the system, they won't fit together.
"They might but not with current tactics, not maintaining equilibrium that we established and not within the framework that also includes wingers who are like specialists in their positions. We currently utilize with defensive, central, attacking midfielders and striker."
From guaranteed positions to competitive roles
The Manchester City and Real Madrid stars have been used in wide positions for England in the past, but Tuchel's selections suggest that the Manchester United forward and the Gunners' star are his first choices on the wing positions respectively.
So can Bellingham, Foden and Kane play together?
Gareth Southgate evidently thought it possible.
Bellingham, Foden and Kane were selected for each England's seven matches at last summer's tournament in Germany, where the national squad lost to Spain in the final.
In the 16 games the stars have performed alongside each other, England have won 10, drawn three and lost three, scoring 36 times and conceding 14.
Tactical insight: Foden's flexibility provides alternatives
Tuchel has utilized a 4-2-3-1 formation that alters structure when England attack.
The young midfielder has been the primary attacking midfielder because of his strong ball-carrying, strike quality and skill in entering the penalty area when the number nine withdraws.
Tuchel has mentioned preferring specialist wingers. Saka and Gordon regularly feature on the wings and can hold the ball well, engage in one-on-one situations, and appear in scoring positions.
In midfield behind the attackers, Tuchel plays with a midfield two consisting of a holding midfielder and one with more license to support offensive play.
So how could Tuchel use these three players?
Foden and Bellingham would be competing with attacking alternatives for the number 10 role, with Kane expected to lead up front.
Foden could operate as the central striker, which theoretically could enable both Bellingham and Foden to feature instead of Kane.
There is one way all three could feature together and Tuchel hinted at it this week.
"At Manchester City, he plays almost like a number eight or 10, so perhaps in coming months we consider him as a central midfielder," 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 number eight, paired with a defensive anchor.
This would then enable Bellingham to operate as the attacking midfielder and Kane as the striker.
Regardless of if Tuchel decides to set England up like this at the World Cup, what seems encouraging is his preparedness to omit established stars in the interest of team harmony.
