I'm watching a not so great stream, I didn't see what happened with his leg. I saw a very slight pull on the shirt, Ramos tripping, and the opposing player falling after the ball was gone.
ya you missed the whole strange leg stays up in the players face/chest thing. It just didn't look like a natural movement.
It could be that he did it by accident, I mean I can't read his mind to know if he does it on purpose, but the leg goes up high very unnaturally.
