I think it's pretty clear he doesn't rate the players beyond the 13; he played them plenty before the break. Those fringe players haven't done a great deal to justify places since the restart.As I said a bunch of times already. I don't think.he knows there's more the 13 players in the squad. He doesn't rotate these days.
I'm not sure if there's much to be achieved with dropping De Gea for the final two games. I'd play De Gea for those, and then give Romero an audition in the Europa League, and reassess for next season.
