Conor McGregor has been mocked by fans over his claim that he will "crush heads" when he returns to the octagon later this year.
The Irishman has been out of action since July of last year, when he suffered a gruesome broken leg in his trilogy bout with Dustin Poirier. But he has been ramping up preparations for his comeback, and has vowed to be unstoppable when he steps in the cage again.
However, fans are unconvinced about McGregor's claims, given his less than stellar record over the past half a decade since his lightweight title win in 2016. The former two-weight world champion has gone 1-3 since the historic feat, as well as losing his boxing debut against Floyd Mayweather in a spirited Las Vegas showing.
