The linesman said he'd been making insulting remarks about his family all game. So? If that's the case, wave your flag, have him booked / sent off, and carry on. But if an official attacks a player, surely they lose the right to speak with authority and be trusted to tell the whole truth.
Apologies if fixtures:
Middle of a game, linesman pushes over player and starts kicking him.
Now you'd think that's the end for the linesman, but no, the Russian FA give the player a retrospective red card.
