you dont have to ask, but its pretty rare when no-one does. and no spur said anything on the bale one.
i think he thought there would be contact, so he starts to fall in the position he would if there was contact. but it dont come, and hes committed, so its to late to stop. thats why i think he never appeals. if he was looking for a freekick, he wouldve asked for one? could be the reason why he wasnt booked or talked to aswell? that play ends with a villa throw in, so the ref knows theres no foul.
or am i being far too lenient, and it was just a plain dive?
the suarez one is more blatant in my opinion.
thats why i thought of the fowler incident. difference was he got up and admitted there was no contact. but he still jumped over seaman and made it look like a foul. and the penalty still stood.
