WBC super welterweight champion Tony "Superbad'' Harrison is not impressed with the trash talk coming from former world champion Jermell Charlo.

Their rematch takes place on Saturday, December 21 from the Toyota Arena in Ontario, California.
  
Harrison and Charlo first clashed on December 22 of last year, with Harrison winning a disputed twelve round decision to capture the WBC crown.

The two were set to meet on June 23, but the rematch was postponed when Harrison suffered torn ligaments after spraining his ankle in training. Charlo instead faced late-replacement Jorge Cota, who was brutally knocked out in the fight.

Charlo has promised to do a lot of damage in the second fight - but Harrison is not concerned with the former champ's warnings or predictions.

"Every time I see Jermell I just feel like he's pretending. He's convinced everyone he's the toughest guy in the world. He gets up here and barks and makes excuses. I beat you the first time and I'm here again," Harrison said.

"If I was scared, I wouldn't be here right now. I didn't take any fight in between. I haven't fought for a year, but I wanted to be put right back in it. I could beat him anywhere, it doesn't matter. We could fight in this room right now. Nothing is going to change. There's no respect. I'm going to show him each and every time. I'm not the one to play with. This isn't Jorge Cota. You have somebody from Detroit. Whatever you want to do, we're ready to do it at any given moment.
 
"His words definitely sparked the fuel in me that's on fire now. He talks loud, but he's not going to do anything. He doesn't have the skill set to beat me. When he fought against Jorge Cota, he was the exact same fighter he was against me. There was nothing different. A leopard doesn't change his spots. He's going to hunt the same. When I say it's all on the line, it's really all on the line. I've never had a fight that's been this important. There's nothing else that matters. This right here can change my life."
