Conor McGregor just went off on Eddie Alvarez -- claiming the guy's an idiot for agreeing to fight him at UFC 205 without signing a fat ass new contract.
You gotta watch the video ... McGregor goes off about how everyone in the UFC is trying to be like him these days -- but there's one huge difference ... no one's cashing checks as big as him.
During the media event, Conor also bragged that he expects to make roughly $40 MILLION this year ... which will help him achieve his goal of dethroning Cristiano Ronaldo on the top of the Forbes list.
Also ... check out the fan who decided to directly talk trash to Alvarez by posing as a reporter ... the reaction is hilarious!
