England's star trio struggle to operate simultaneously - is Tuchel right?
With six wins out of six, zero goals allowed and tournament placement confirmed with matches remaining, England manager Thomas Tuchel could suggest he has got all of his big qualifying decisions correct.
Nevertheless, in the build-up to Thursday's home game against Serbia, he sparked a debate when he claimed that three of the England's elite footballers - Jude Bellingham, Phil Foden and Harry Kane - struggle to perform in the equivalent formation.
"Presently, if we maintain the formation, they are unable to feature.
"They might but not within this system, not maintaining equilibrium that we developed and not for the structure that incorporates wingers who are like specialists in their positions. We play at the moment with defensive, central, attacking midfielders and striker."
From guaranteed positions to competitive roles
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 wide areas respectively.
But can Bellingham, Foden and Kane operate simultaneously?
Former Three Lions boss apparently believed they could.
Bellingham, Foden and Kane featured in every 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 three have featured simultaneously, England have won 10, 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 alters structure when England attack.
Morgan Rogers has been the key creative force because of his strong ball-carrying, shooting ability and skill in entering the penalty area when the number nine withdraws.
Tuchel has discussed favoring specialist wingers. Saka and Gordon consistently operate in wide areas and can retain the ball skillfully, engage in one-on-one situations, and appear in scoring positions.
Behind this front four, Tuchel utilizes two central midfielders consisting of a holding midfielder and a partner with attacking liberty to join the forward movement.
What solutions exist for the trio?
Foden and Bellingham would be vying against Cole Palmer, Morgan Rogers and Eberechi Eze for the number 10 role, with Kane expected to lead up front.
Foden could operate as the main forward, which in theory could allow both Bellingham and Foden to play at Kane's expense.
There is a potential solution all three could feature together and Tuchel alluded to it this week.
"For Man City, he plays almost like a number eight or 10, so potentially in future we regard him as a central midfielder," he said.
Foden has been used in a more all-purpose midfield role this season.
That has permitted him to contribute from midfield and could categorize him as the advanced playmaker, alongside a holding midfielder.
This would then enable Bellingham to operate as the attacking midfielder and Kane as the nine.
Irrespective of whether Tuchel decides to set England up like this at the international competition, what bodes well is his willingness to leave big players out in the interest of team harmony.
