The best side England can put out imo is
------------------Pickford
Walker---stones---maguire---shaw
--------------------Rice
---------Bellingham----Mount
Sancho--------------------------------foden
--------------------kane
I don't get this "we can't play just one DM against good sides" why the hell not? Do you think France, Portugal etc will be thinking like that? Have some fucking confidence in your players, play the best players in the best form in their best position and trust them to be better than the rest. Starting with 2 holding midfielders particularly when we don't have 2 good fit holding midfielders just says inferiority complex before we've even kicked off.
That team above would have a genuine chance of beating anybody and with quality options from the bench too but there's zero chance we see something like that from southgate.
It will be 2 sitting, Mount easily crowded out of the game and England looking completely devoid of ideas against every side we face despite having arguably the best attacking in Europe. Subs will be like for like and everyone will struggle because of the formation.
