No, I don't think it's a corner turned with THIS lot of players. We've seen similar performances under Amorim where we've gone to Arsenal and City and played well insofar as keeping possession and not giving up multiple chances, without creating a hell of a lot of chances ourselves.
The difference in this game is that Liverpool had a defender who was phoning it in and we exploited that and created chances.
I think what it does show is that Amorim's system does work if the players are good enough and consistent enough. But I don't trust (a lot of) these players to replicate that performance, that's the problem.
