Of course there is nothing wrong but we also need to see the opportunities and support to predict the strength of one of the teams that want to compete for the title. Manchester United is indeed much better now but we see that there are still many things that need to be done by Amorim, in the Premier League they lost to Arsenal so there are still many things that need to be fixed or improved. For this season Manchester United is still trying to build team performance and I have not seen their chances for the title competition will be more open, but anything can happen if Amorim can change Manchester United to be better in a short time.
I think sometimes a team has something that is being prioritized. I mean maybe in the EPL when playing against Arsenal, MU was only able to get a defeat but in fact when playing against other popular teams like Chelsea etc., Man United had good results. On the one hand for me the performance in the EPL will not affect MU performance in the European league. Because maybe for Amorim chasing the EPL title is something difficult and will prioritize the European league title to get a more prestigious title and appear simple when playing against top teams in the EPL.
I have not seen any significant improvement since Amorin came to Old Trafford, Manchester United is still a team that fills the middle of the standings. Amorin's target in the Premier League is to finish in the top 4 of the standings because Amorin wants to bring Manchester United to the most prestigious competition in Europe, the Champions League. And of course this is not an easy target for Manchester United to achieve, considering the competition at the top of the standings is quite tight.
On the other hand, the target to win the UEFA Europa League trophy can be said to be quite realistic because there is still a chance for Manchester United to advance to the next phase, although in the remaining three matches they will face a fairly strong team. This is not easy, but if Amorin is able to make positive changes in your body and is able to perform more consistently, then everything will be possible.
