He blamed former manager Mark Hughes of bringing what he described as 'maggots' to the club.
Joey Barton: "Too many w*****s amongst the playing staff. All brought in by Hughes. Some good lads but not enough. Too many maggots.
"Hope they can get a load out, if not they'll end up in a Wolves situation because trust me that Championship is a f*****g hard league.
"League table doesn't lie. Both sides haven't won enough games to deserve to stay up. Reading in a better position than QPR though.
"I can't believe QPR have just been relegated and Bosingwa was walking down the tunnel laughing! Embarrassing. Show some guts man."
