Watched the footage of it, ref is clearly some smug, clueless cunt. Looks like the linesman is saying that he knows it should be a retake so Lascelles, Perez and one of our coaches tells him to go and tell the ref.
It takes over five and a half minutes from Gayle going down to them being allowed to take the free kick, over four and a half of which is after the penalty has been taken. Even if there were no other stoppages in that half, how in the actual fuck he gives just 3 minutes of stoppage time is almost as bad as the incident itself. Useless prick.
