Villa could have done a lot more damage as a starter because we needed a goal soon. Roura & Tito decided that it was best to bring him on when we were 0-2, with 30 MINUTES LEFT and we needed to score 3 goals... lawl. Everyone from Barca knew it was over so they weren't motivated and Mourinho just told his players to defend, and even changed Ozil for Pepe.
The task brought to Villa was mission impossible, even Messi can't do it. I just can't believe why the FUCK the staff did this. Everyone, every single Barca fan knew this would happen, there were polls with insane amount of votes of up to 98% in every single newspapers telling the staff to USE VILLA. However, they said "let's try Cesc one more time, if it doesn't work we can get Villa in and he will solve it, hahaha". I can't believe a bunch of fans know more about football than these so called "experts".
