England have to find the management and mentality to somehow take themselves somewhere they have never been since 1966.
Tuchel built a side in a Premier League image with lots of physicality and moulded around their two world-class players – Bellingham and Kane.
As yet, however, there is no clear idea or pattern of how they can reshape quickly ahead of Euro 2028 and actually win a tournament.
And, of course, they will face France and Spain at those Euros.
Tuchel needs to find a way to make England more potent and resilient, less one-dimensional, and he will be able to draft in the emerging, brilliant talents of Liverpool’s 17-year-old forward Rio Ngumoah and Arsenal’s Max Dowman, only 16.
The head coach did appear to let the handbrake off against France on Saturday (admittedly in a game with little pressure) and his rejigged side proved they can dazzle in attack with their six-goal display.
Nevertheless, clouds still hang over how England solve this puzzle after another failure – and the pressure is on Tuchel to come up with the answers.
