For the trophy issue, it might still take time because there are still weaknesses that need to be fixed by Amorim and I saw the defeat they got when they faced Arsenal where their defense still has work that needs to be completed by Amorim. At least this is a good start for them although now people are starting to compare the defeat they received from Arsenal with the victory they got when they faced a much weaker team. For the Europa League, I am a little pessimistic that Manchester United can win it but who knows if they will focus on winning it.
Actually there is nothing wrong if we say Man United is one of the worthy candidates to hold the UEL title and I agree with you that we all do not know what Amorim is planning. Because it makes sense that in the EPL maybe MU lost against Arsenal but in the UEL we have seen good improvements and can have a big influence on MU to continue fighting until the final round later.
I also agree that actually Amorim only needs a little improvement in the defense line and in january Amorim chance to try to fix these weaknesses.
