Probably one for the football pet hates, but I hate it when people moan about people trying to get an opponent booked or now the above.
If that person's clearly cheating then fair enough, but 7 out of 10 times I'd say the player who's protesting is normally spot on.
A better way would be if a player is asking for a VAR review, it gets reviewed. If it's blatantly a wrong appeal, he gets a yellow or some.sort of suspension for being a tit and a cheat. If he's right then the ref has come to the correct decision.
or as in the NFL, they have a certain amount of times to ask for a review.
