Sort of, but they also have the experience having done it before so shouldn't be caught out on the negative aspects of being holed up for a tournament.
The concern for me is that he's replaced Trent for an actual midfielder, then Gallagher for one of Mainoo/Wharton, and we still look bad. This doesn't look like a team which can just be tweaked a bit to be good. Maybe they are holding some effort back for the latter stages when they need it, I hope so.
