Conor McGregor appears to be amused by the idea of a potential Kamaru Usman vs. Saul 'Canelo' Alvarez boxing match. Usman recently hinted at the possibility of a crossover boxing clash between himself and Canelo in the same vein as Conor McGregor vs. Floyd Mayweather in 2018. The former two-division UFC champ appears to have been tickled by Usman borrowing a phrase he famously said during an interview with The Schmo. McGregor went as far as posting on his Instagram stories to express his enjoyment.Conor McGregor reacts to Kamaru Usman's comments [Screen-grabbed from Instagram]In the aforementioned interview, Usman revealed that he might push for a boxing match with Canelo after his rematch with Colby Covington. He then said it would be the first time the top pound-for-pound fighter in MMA squared off with the top pound-for-pound boxer. If the phrase sounds familiar, that's because McGregor said the same thing ahead of his clash with Mayweather in 2017.Speaking about a potential clash with the Mexican superstar, 'The Nigerian Nightmare' said:"I might have to go drag Canelo out... when he's done with all these guys that he's running through. I mean, it's never been done. I might have to drag him into... if not in the octagon, I might have to drag him in the ring and actually take him. Cus' it's pound-for-pound, never been done. Pound-for-pound MMA fighter and pound-for-pound boxer. So, that might be next."Check out Kamaru Usman's full interview with The Schmo below:Kamaru Usman warns Conor McGregorThis wasn't the first time Conor McGregor has fired a passive-aggressive shot towards Kamaru Usman.
