Way better after today, both signings and the performance (after the first 30 which was very concerning).
As a main group I think we'll see this:
Onana
Dalot De Ligt Martinez ???
Casemiro Mainoo
??? Bruno ???
???
The wings will be Amad, Garnacho and Rashford battling it out all season, always having one sub in for one of the other 2. Expecting big things from all of them. Up top, Hojlund and Zirkzee should rotate well. Left back obviously Shaw if fit, but Mazraoui will play his fair share there. Yoro will be eased in post injury now.
Concern is in midfield. Mount can backup Bruno even though he doesn't need much rotation, maybe can step in for Mainoo when needed too. Casemiro is the one that I'm not confident he can keep up the level he showed today, especially without rotation.
Eriksen, McTominay, Sancho, Antony, Malacia, Maguire and Lindelof all have weird roles in that some might get games to start the season but once everyone is fit I'd imagine they start pushing for transfers due to no game time as they are deeper backups.
