In the Premier League I support United, but there should still be more worthy teams in the final. Bilbao and Lazio, for example, are fighting for the top 4 in their national championships (ticket to the Champions League), while Tottenham and United are fighting to at least leave the second half of the tournament table

I understand that these are different tournaments, but United are too bad this season. And I also think that fresh names in the finals are more interesting.
I am not expecting anything better from Manchester united. Manchester United is a weak team this season. Even against smaller teams, we have not seen Manchester united play well. Manchester united is in 15th place in the Premier league table.
We have seen better performance from Manchester united in the last few matches of the Europa League. However, I cannot consider Manchester United as a favorite for the Europa league title. It is not possible to win the Europa League title with such weak and irregular performance.
Manchester United is going to face Real Sociedad. Madrid is lucky that Real sociedad's performance is also very irregular this season. So Manchester United has a chance of winning.
I suspect it will be a tedious encounter. In La Liga, Sociedad have a goal difference of 23-23 in 25 games. It is unlikely that we will see any bright games and perhaps the outcome of the confrontation will be decided in a penalty shootout. United are favourites in this pairing but even the first game could turn everything around, as United have often failed this season.
