Conor McGregor has talked a lot of trash about knocking out Floyd Mayweather in their upcoming fight this weekend but once upon a time the UFC star claimed Mayweather was unbeatable in a boxing ring.
Back in 2015 after Mayweather easily beat Manny Pacquiao, Conor sent out this tweet which has now gone viral again.
Conor probably still knows that Mayweather is unbeatable in boxing but at least he’s getting paid $100 million to find out.
