I guess the Premier League is just a level above any other league at this point. The Madrid clubs, Barcelona, Bayern and Inter might be able to compete. But everyone else is just fodder.Because they don't have enough quality apart from 3 players and one of them couldn't even play in both legs. Still even if they were available Bilbao couldn't match utd.
Brentford and Brighton can easily beat Bilbao in both legs too
