Ideally, I'd have liked to have seen Amad for a bit longer but, apart from that, I think Ole's handled tonight fine.
Put out a strong team, as he should have, but been able to not use Rashford, rest Pogba after 45 mins, give Fernandes 20 minutes rest, and give Van de Beek a good run out while reintroducing Mata for a bit.
Most of the youngsters aren't first team ready but are gaining good experience. Just Amad probably should have had a bit more of a run out (EDIT - but he's on now), but that's a small thing to complain about on getting through to a S/F.
