I think this squad looks pretty good. hes included all of the young exciting players that I think most of the fans want to see in there (grealish, foden, saka, Bellingham). I'm a bit worried about CM tho as Henderson and rice may not be 100% fit as they missed the last part of the season, and mount might be quite tired as hes played an awful lot of games.
I disagree on Walker though, I think he is a good player, his blistering pace means he rarely gets done and also he could play RB in a 4 or CB in a 3.
But like tom says all depends how they perform. I am scarred from previous tourneys where we scrape thru the group, and then get beat by a better team a la Germany, France or Belgium.
