GRAPHIC LANGUAGE WARNING.

One West Coast fan took his western derby celebrations a little too far on Sunday.

Shortly after the Eagles’ thrilling eight-point win over Fremantle at Optus Stadium, this fan thought it would be a good idea to burn an opposition jersey.

He is captured on video outside the Burswood venue attempting to light a jumper with injured Docker Michael Walters’ number on it.

The middle-aged man, wearing an Eagles cap and polo shirt, wasn’t too popular with passing fans as he yelled “f*** you Dockers” several times.

“You’re an idiot,” one lady yells, before attempting to pull the jumper out of his hands.

The Twitter user who posted the video wasn’t impressed either.

“Classy display from some @WestCoastEagles supporters after their win in the derby tonight, burning a shirt with injured @freodockers player Micky Walters’ (number on it). What a pack of dogs,” he tweeted.
