Barcelona best team ever?

On pes 2011 maybe but in real life they are a joke. Can any of you bandwagon barca fans please explain to me why Barca did not get booked for diving i think it was Busquets holding his face for no reason. Also messi's handball when he was on the floor it was intentional. If a defender would have dared to touch messi in the build up to the second gol they would have gotten a straight red cuz noone can touch messi. Why do refs help barca ? How would barca do 11vs 11in a big match?
