Amorim was brought in for longterm and he will have 2-3 seasons at least. He got the position in the worst possible time and with this kind of players he is doing the maximum. If he is able to win the europa league this season will be a good season for them. This is the only thing that can save their season so far. Even if he dosent win it i dont think he will be sacked.
Well, if given a long time, of course Amorim will succeed in bringing change to the Manchester United squad. So far, Amorim's performance has certainly not been good, but we must also look at the depth of the squad because the existing squad cannot perform well so that management needs to make changes to the squad in the upcoming transfer window.
The position in the standings does not reflect good performance because until week 29, Manchester United is still stuck in 13th place. There is no target that they will pursue in the Premier League because they don't have much time left. But Amorim's focus is of course on the European League so they have to play well to be able to reach the final.
