Easy remedy though..
Get the ref mic'd up and any footballer telling him he's a fucking useless, cheating, result manipulating, bent, fkin w*nker* gets an instant red card and a 3 game ban..
Repeat offenders are instantly banned for the season..
The swearing would soon stop ..!
Works perfectly in rugby, huge guys smashing into each other and then showing the match officials the upmost respect when they get pulled up for dislocating the opposition hooker's bollocks..

If said by any City player or employee of Manchester City Football Club to the useless, cheating cnut in the middle during a game, the ref is obliged to instantly stop the game with a blast of his whistle, firmly shake the player's / employee's hand and say into his mic, "it's a fair cop, we've been fucking your club over for years and will continue to do so"..
..... then restart the game with a drop ball..!
