about Nani vs Arbeloa incident: let's try to put it this way. Nani sees that Arbeloa is running for the ball and he does the same. He tries to control the ball and jumps, so does Arbeloa. The difference is that the Spaniard slipped and is lying on the floor. Now Nani doesn't see that but he lands his studs on his neck. Do you think that's a yellow card? Right decision, ref.
