There are definitely flaws in their plans, Manchester United's defense is a little weak but those of us who understand football fairly well must say their midfield and attacking line-up is very strong yet they cannot do well with this team.
It is quite likely for us to see Manchester United defense getting better. Have you heard of the most recent transfers? They have signed Mazraoui and de Ligt. They are aiming to sign a defensive midfielder also.
These are good steps to take to fix defensive problems at a big rate. Europa League winner odds aren't determined yet. But I expect Manchester United to be one of the biggest favourites of course.
It isn't unrealistic I think. It is all up to having a working system after making the right transfers. I hope ten Hag won't fail about that this time.
Currently, I don't think that Manchester United has more problems in their defense line, despite not having played many matches. Even from their last match, we saw how their defensive line was very active. However, it would be good if they could add more players to strengthen the defense, if possible.
As for predicting the favorite team to win the Europa League trophy, I don’t think our predictions make much sense right now because the competition hasn’t started yet. We need to see the teams' performances before making accurate predictions. There may be some teams that we wouldn’t consider top favorites for the Europa League trophy until the competition begins and their performances become evident. Last season, for instance, I don't think anyone anticipated Atalanta winning the Europa League trophy before the competition started.
