As you saying he bluffed? Because he definitely signalled advantage and put his whistle to his mouth.No chance, he just wasn't going to give it.
He signalled well before it was a certain goal.He did an outrageous windmill advantage about half an hour after the ball was in the net!
He would've had to. Also, whistle to mouth is an instinct, I doubt he did that for effect, the signal would've been enough.My point is he only signalled advantage to milk it, and there's no way he would have pulled it back for the penalty if Silva missed.
