Chavez Jr vs Martinez Video Preview: The Match-Up and Sergio's Stolen Title

[ Full Coverage: Chavez Jr vs Martinez ]

Julio Cesar Chavez Jr

"(Martinez) has been talking so much in the last year or so that it's getting to me, in a good way. On the 15th, I'm going to go in there, I'm going to knock him out, and I'm going to shut him up for good."

"We've had some encounters at the press conferences, and he has said that he is going to win, that he's too good of a fighter for me. But I'm ready, that's why I agreed to fight him. And I'm going to prove it to him on September 15th."

"I'm younger, I'm stronger, I'm smarter, I'm a better fighter, and I want it more than him. That's why I made this fight, because I want to shut him up. Because he's a clown with a big mouth."

Sergio Martinez

"He is someone who has something that belongs to me: The middleweight championship belt. That is my main motivation. It's my greatest motivation. And that is what is driving me."

"I've been working hard for many, many years. And those years of work have given me strength, speed, intelligence, and a lot of heart. A lot of heart."

Bernardo Osuna, ESPN

"The belt was taken away from Sergio Martinez basically to be handed to Julio Cesar Chavez. Every time he steps out into the ring, he knows he needs to impress in order to get a shot at Chavez, in order to make things right, and that's why this is a grudge match for Sergio Martinez. He wants to prove that that belt never belonged to Julio Cesar Chavez, and he feels that the only way to do it is to knock out Chavez."

"This is a fight the fans have been asking for. They can't get Pacquiao-Mayweather, they can't get a whole bunch of other fights. Fans have legitimately said, this is a fight we want. This will prove whether Chavez is for real or if he is just a figment of a promoter's imagination. Sergio Martinez is legit, and this is a fight that Julio Cesar Chavez Jr has to win."

Kevin Iole, Yahoo! Sports

"I think you have to give the fighters themselves credit. It would have been easy for Sergio Martinez to say, 'You know what, there are other guys for me to fight. I'm not going to take on this guy.' Julio Cesar Chavez Jr said, 'I wanna fight the best, I wanna go out there and prove myself.' They made it happen. It was the two guys themselves."

Lou DiBella, Martinez's Promoter

"Sergio is called a Diamond champion, he's called the pound-for-pound best. He's rated by every magazine including Ring Magazine as the real middleweight champion. When you go back in the history books, though, for a couple of years it's gonna say that Julio Cesar Chavez Jr was a world champion, not that it was Sergio Martinez. Sergio really, really got pissed off by that."

Julio Cesar Chavez Sr

"I don't like (Martinez's) style. It is not a conventional style, because he drops his hands, and he runs too much. He is a fighter that stinks up boxing."

Sampson Lewkowicz, Martinez's Adviser

"Chavez Jr is slow for this weight. The problem for all Mexican fighters is speed. Hopefully, Freddie Roach has the heart to stop the fight, and not further damage the career of Julio Cesar Chavez Jr."

"I can guarantee you that on September 15th,

Freddie Roach, Chavez's Trainer

"Sergio, he's a great athlete, but I don't think he's a great boxer. He doesn't have the experience. I don't know his trainers and I can't criticize what I don't see. But the end result of what I see is he doesn't have a lot of experience. I think we'll break him down and knock him out."

Pablo Sarmiento, Martinez's Trainer

"All Freddie Roach can do now is talk. He's going to know who I am when I enter the ring with Sergio. He knows he's facing a big problem with Martinez, because he knows his fighter doesn't have what it takes to beat Martinez."
