Exactly.
Amorim is struggling, no doubt. The tactical side is one thing, I think he's been tactically good. But the lack of consistency of performance, or rather the consistency of poor performances, he's clearly struggling with just as his predecessors were.
But the rule applies - he came in midseason, he had no hand in hsaping the squad at all, he deserves patience. That means he is granted a period where he is struggling.
As for the second quote, I posted it elsewhere - that patience cuts both ways. The players too deserve patience to grow into playing under Amorim, and yes, it is a manager's job to get the best out of a squad and improve the performances of the players that are there. Else we wouldn't have needed to hire a new one.
So if people grant Amorim time and patience, in the meantime it makes no sense to berate all the players as useless and shit. This is our team, it needs to get better together, manager and players. Notwithstanding sensible transfers of course.
