Paul - who is linked with a fight against Mike Tyson - has history with Mayweather as his older brother Logan fought him last summer.

One thing he has in common with Floyd is that he retired undefeated. Khabib called it a day at 29-0 and defeated the likes of Conor McGregor - an opponent Mayweather also beat - alongside Dustin Poirier and Justin Gaethje.
