'The Problem Child' responded by saying:"Kamaru Usman: "boxing is dying" Also Kamaru Usman: "pls Canelo fight me for a payday"Check out the tweet below:Jake Paul@jakepaulKamaru Usman: “boxing is dying” Also Kamaru Usman: “pls Canelo fight me for a payday” twitter.com/usman84kg/stat…KAMARU USMAN@USMAN84kgOur fans know who the best is because “The best fight The best” not run & hide and fight nobody’s with those plastic belts & call themselves “super champion”.

The YouTube star, of course, is one of the most prominent trash talkers in combat sports, known for trolling UFC fighters and the entire MMA community.Usman has been lobbying for the Canelo Alvarez fight for quite some time now. The top pound-for-pound octagon warrior recently got Alvarez to respond, although he didn't exactly get the reply he was hoping for.Canelo Alvarez@CaneloYou calling me out right ?

During an interview with Fight Hub TV, 'The Problem Child' said:“I think Usman’s manager is right in a sense. Even though he’s a rat, we all know he’s a little scumbag criminal, liar, got kicked out of a country — so I think his manager’s a piece of shit, don’t get me wrong — but I think he’s right in the sense that Canelo is ducking a lot of people. You know, fight Benavidez, fight Charlo, why aren’t those fights happening? And, you know, he’s not fighting any really big names. These guys are relatively unheard of."Check out Jake Paul's comments below:
