By Chris Williams: WBC middleweight champion Julio Cesar Chavez Jr. and WBC Diamond 160 pound champion Sergio Martinez met with HBO’s Max Kellerman recently in their Face off on HBO. The two fighters seemed to genuinely dislike each other and Martinez hit a nerve when talking about Chavez Jr’s father during the interview.

Here’s some of the back and forth discussion that went on:

Kellerman to Chavez Jr: “How do you keep Sergio Martinez off of you”?

Chavez Jr: “I’ll just do my thing. I’ll be prepared 100 percent to fight all rounds. That’s the only thing I’ll need to beat him.”

Martinez: “You’re living in a delusion, based on your legendary father. When are you going to stop believing that?”

Chavez Jr: “Is that what you think?”

Martinez: “When will you start being just Julio Cesar Chavez, your own person, not just the son of so and so.”

Chavez Jr: “I’ll never stop being my father’s son.”

Martinez: “Of course not, but once you’re in the ring, it’ll be just you alone and not with your father.”

Chavez Jr: “When I knock you out on September 15th, that day I’ll be whoever you want me to be. This [Chavez Jr points to his own chin] is the best chin.”

Martinez: “How can you fight someone you can’t hit?”

Chavez Jr: (laughing) “You think I can’t hit you?”

Martinez: “I’ll sign on the dotted line.”

Chavez Jr: “Where will you hide?”

Martinez: “No, I’ll be hitting you.”

Chavez Jr: “What do you think about the time you lost in Las Vegas against a Mexican? [Chavez Jr referring now to Martinez’s 7th round TKO loss 12 years ago to Antonio Margarito in 2000)]. This will be your second fight in Las Vegas and against a Mexican.”

Martinez: “I have the rematch that I wanted. I will probably make you retire from boxing, because I am going to beat you up. I am going to hurt you, because it’s written or I’ll write it down.”

Chavez Jr: “I just want to wish him luck, a lot of luck. On September 15th, you’ll realize what type of fighter I am. I’m not just the son of Julio Cesar Chavez, you’ll see. I am the new Julio Cesar Chavez.”
