That’s some punch, in fairness.

Paul, meanwhile, told Jim Gray: "I talk a lot of s***, but I back it up."

"He was better than I expected, athletic, he was super strong. It takes a lot of balls to step into the ring.

"This means a lot to me. It feels good to win."

Paul then raised eyebrows by insisting he will knock out MMA duo Conor McGregor and Dillon Danis.

Paul then backed up his original statement by tweeting: "I mean what fighter with this big of a platform is calling out Mcgregor? ITS GONNA HAPPEN. YOU WILL ALL SEE."

You have to admire his self-belief.
