Khabib is calling out Mayweather after the fight with McGregor. Khabib is saying that he managed to drop McGregor but Mayweather didn't and there can only be only king in the jungle and that's him. I can see that Myaweathers manager is with Khabib and they are laughing about it so I think this is a joke, but hey who knows. Maybe if Khabib and UFC don't get along, this might be the way Khabib will take. I do not see Khabib winning this though. No way no how. Once again, I think this is a joke... but who knows what might happen.
