Conor McGregor has been called a 'piece of s*** scumbag' by the manager of UFC welterweight champion Kamaru Usman.
McGregor accused Usman of stealing his material after the Nigerian said it was 'green panty night' when rivals fight him because of the money his fights generate.
The Notorious previously told former lightweight champion Rafael dos Anjos that the Brazilian's wife would 'break out the red panties' if the pair took to the octagon.
"Am I tripping or is this jackass always at this? Everything I say," McGregor posted on social media.
But this remark has triggered Usman's manager Ali Abdelaziz to slam McGregor and claim that he is running scared of the UFC champion.
"Listen, Conor McGregor is the biggest piece of s*** scumbag in the sport, Abdelaziz told TMZ Sports.
'Kamaru Usman is a great father, great husband, he's not a jackass If you have a problem with him, fight the man. But we know Conor doesn't have the balls.
"He's not enough of a man to fight anything like Kamaru. He's not enough of a man to even look him in his face.
"If he look him in his face, he's going to probably say 'Hello, how are you, how you're doing sir?' Because this is like a grown man fighting a little girl, right?"
Abdelaziz added: "The Internet creates a lot of heroes. Everybody can talk s***. But realistically, if you put these two guys in a cage, in a street fight, in the trunk of a car, in a jail cell... you know who's gonna be whose daddy.'
"Kamaru Usman will be Conor's daddy every day of the week."
