For me there is two obvious errors.
Braitwaite is a clear one, Dunk in his two recent games looked miles out of his depth for England. The other issue is left back, we only have Shaw. Tripper and Gomez are horrible left backs, he is young but we should have chosen Lewis Hall.
If Stones and Shaw aren’t fit (which is a big risk) this is the backline
Walker Dunk Guehi Tripper
So that is the mediocrity of Dunk and the unsuitability of Trippier. If Stones and Shaw can’t keep fit we will not win the Euro’s, no chance.
