UFC superstar Michael Bisping has a message for Georges St-Pierre -- I'LL FIGHT YOU WITH ONE ARM!!!!
The middleweight champ was out in Burbank on Friday when he told us what really went down behind the scenes with GSP -- and why the two couldn't get a deal done for UFC 206 in Toronto.
But Bisping's past that now -- he wants a piece of Nick Diaz ... claiming the fight would be PERFECT for 206 and they could both make a ton of money in the process.
Nick ... thoughts????
