Since he started managing Manchester United it is very clear from the performance of the team that he is making a good change, Manchester United have been doing well with their recent games. I think this is the beginning of the transformation of Manchester United, they might not win trophy in this season but it will be better for Manchester United to have impressive results this season, then after they might have build up good strength this season they can think of having a target of winning trophy. Amorin should focus more on developing a better tactics.
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.
