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.
And Bilbao has 6 win with 1 lost and 1 draw for 8 match while Roma can only save 3 win with 3 draw and 2 lost, clearly talking about the strength of both team Bilbao is still superior, but in the first match they also met and the result was 1 - 1 draw.
First leg match later will also be the same as their first meeting where Roma is the host, if Roma can play well maybe the result will be draw but in the second leg Bilbao will benefit from the home game so if the first leg is draw Bilbao can still win in the second leg to get an aggregate advantage and advance to the next round.
