I think that Roma is not strong enough to compete with Athletic Bilbao, for them this is a special EL, because the final will be held at home and they really want to win. Manchester United were also unlucky with the opponent, in the state they are in now, I do not believe that they are capable of beating Real Sociedad. Fenerbahce can compete with Rangers, but then they will get to Bilbao, it is unlikely that they will beat them, I think Mourinho understands this well.
Roma and Atletico Bilbao have a fairly large gap from the match victory obtained in the UEFA Europa League this time, from the standings it is also quite far, namely Bilabaoo is in second place while Roma is in 15th place, of course it is very far when compared, even Bilbao is competing with the first position, namely Lazio, only a goal difference with the first position that makes it not get it.
Regarding Manchester United, I am still quite confident in being able to beat Real Sociedad even though it takes a very hard struggle, unfavorable conditions do not mean they can stop them at this point and I think Manchester United can do it all, because the biggest hope this season for Man United is in the UEFA Europa League.
