If they fall short here, it would be fun to see RM and Man U fight for the Europa League hehehe.
UEL competition will be more interesting this year if it happens, because we will see a lot of top clubs in their country, Roma, Napoli, Milan, Lille, Leichester, Tottenham, Villareal, MU and (Madrid or Inter), I think if Madrid filled the UEL spot, My Prediction Madrid will be going to Final. Based current domestic league performance, I wish the Final will be Madrid vs Milan 
RM players are going to play for the club's pride and honor. I don't think they'll be interested playing in a "lower level" tournament but let's see.
Aren't you a bit rude for not including Arsenal on that list? They used to be a big shot as well and they've won all their matches so far. Hopefully no Gunner was hurt there hehehe.
