JULIO CESAR CHAVEZ JR., Former World Champion
"I had a great training camp. I feel better than ever. I am ready for the fight.
"I know that this is a new weight class for me. I realize that Fonfara is very tough and bigger than me, but I am up for the challenge.
"I have worked on my boxing during my one year off, and I am very excited and motivated to get back in the ring.
"I have worked so hard for this fight because I am fighting in a new weight class. I must punch harder, so I have focused on getting stronger during this training camp.
"I have a great chin, I know how to take punches and my conditioning is great. A lot of fighters can take a punch, but I can take multiple punches and not be hurt.
"I think that Andrzej Fonfara is one of the best fighters in the light heavyweight division. Inside of boxing, everyone knows who Fonfara is. He knocked down one of the best boxers in the world in Adonis Stevenson.
"Fonfara is disciplined in the ring, but he doesn't vary his punches.
"I understand that my dad didn't want me to take this fight. I had bigger names I could've fought, but I think that Fonfara is a great challenge for me and I like the challenge.
"I would like to thank SHOWTIME for making this fight happen."
ANDRZEJ FONFARA, World Title Challenger
"I'm prepared very well and I'm ready for this fight. It's been a great camp like always. I train hard for each fight. I'm a tough boxer who is feeling great. The weight is good and everything is perfect.
"I must put everything into Saturday night and I will win the fight.
"I must look even better than I did against Stevenson. Everyone said I looked good, but I lost the fight. I didn't want congratulations because I did not win the fight. But this time I will win the fight. I'm ready for a decision or for a knockout.
"I'm ready with a couple of plans. I don't want to run around the ring, I want to fight tough. I'm going to use my jab and my right hand, which is my best punch.
"I'm not worried about what his father said about not fighting me. Chavez Jr. wants to fight and I will show him that his father was right.
"It doesn't matter how I win, I want to win this fight and get my rematch with Adonis Stevenson.
"Chavez Jr. is a great fighter. He uses a lot of combinations and has a powerful punch that I must be ready for. I want to show the whole world how good I am when I win this fight on Saturday.
"If I get the chance, I'm going to knock him out. It's boxing so you never know what will happen. I want to box round-by-round and win this fight.
"I lost the fight with Stevenson but I showed that I was a good boxer. I'm a much smarter fighter now because of that experience. That was a fight at the top championship level.
"It doesn't matter what Chavez Jr. says at a press conference, we'll be in the ring Saturday and everything will happen there.
"Fan's can expect heavy punches, knockdowns and a great fight."
AMIR IMAM, Undefeated Super Lightweight Contender
"I'm confident going into this fight because of how I train. I have put my heart and soul into this sport since I moved to Florida three years ago. I left everything behind to better myself.
"I'm going to stay smart and composed in there and do everything I can to get the win.
"I don't feel like I need the knockout to come away with a successful fight. But, you better believe that if there is an opportunity to knock him out, then I will take advantage of it.
"In 2015, I want to become a world champion. This is my breakout year. A lot of people have been buzzing about me. I want to become the WBC world champion, that's what I'm heading for.
"I know he's [Castillo] a good opponent, he's got a great resume, and he's coming to fight. He has a great record, so that alone shows what he's capable of. Come Saturday night may the better man win.
"I've boxed styles like [his] plenty of times, but you never know, he could come out different Saturday night.
"I'm ready to put on a great show for the SHOWTIME audience."
WALTER CASTILLO, Super Lightweight Contender
"I'm coming here to fight. I can tell you one thing, Amir Imam made a big mistake by taking this fight.
"I've fought a lot of tough fighters; my two losses were by decisions where I feel I was robbed. I've fought better fighters than Amir has.
"Come Saturday, I'm going to announce to the whole world that Walter Castillo is here to stay and he's going to be a world champion."
JULIO CESAR CHAVEZ SR.
"Being in Los Angeles is like being in Mexico for me; I have had many great memories. I became the world champion for this first time here and my son also became the world champion for the first time here, too.
"Julio definitely has a very difficult fight ahead of him.
"If I was Julio's manager, I wouldn't have taken this fight. Fonfara is a difficult and tough fighter.
"My son wants to fight fighters of quality and wants credibility in boxing.
"Julio has worked and trained very hard for this fight .He has the capability to win and we expect that it will go very well."
JOE GOOSSEN, Chavez' Trainer
"Julio has a window here the next five, six, seven years that he can capitalize on.
"I think he's left the childish stuff behind, and we're all guilty of being childish.
"I think that Julio has surprised his father with his determination heading into this fight.
He's got a left hook to the liver that just sends a shock through your body.
"He's not soft. He's a real fighter. I have been around enough fighters to know that he's a real fighter. Number one, he has the never-say- die attitude in there.
"We're up against a very well-schooled, blue collar, workmanlike fighter in Fonfara.
"He is an athletic, improvisational fighter, in that you don't know where everything's coming from.
"I've watched a lot of Fonfara tape, and he pretty much repeats what he does, but he repeats it well.
"This is going to be a battle. You've got two contrasting styles and personalities.
"Julio has 51 fights under his belt. He's no rookie and he comes from a great bloodline. (In the short time I've been with him, it has been) more of an association than a dictatorial effort between the two of us.
"Based on former camps, he's never really extracted himself from comfortable surroundings and put himself in a position where he is completely isolated like he was in Lake Tahoe."
SAM COLONNA, Fonfara's Trainer
"Fonfara could turn it up whenever. He could be down on the scorecards and one punch he throws could change someone's world. He's proven in the past that he has power in both hands.
"The styles in this fight are perfect for each other. When people ask about the fight I say it could go either way, it depends on who catches the other first.
"I'm looking for Fonfara to dominate, but Julio Cesar Chavez Jr. is a warrior, he comes to fight, he knows how to go to the body like his father used to, so we've been working on all of these strategies.
"A knockout win would be a dream come true to me. That's what I've been looking for all these years. Winning this huge fight would change everything for Fonfara and myself.
"This camp that Andrzej had was the best we've ever had. He worked hard, he had time to train and there's no excuses.
"We're coming to fight a war. Don't forget that wars are won by strategy.
"People say to listen to your father. His father told him not to take this fight, but he took it anyway and that was a mistake.
"I see this fight not going past 10 rounds, with us getting the knockout."
STACY MCKINLEY, Imam's Trainer
"Amir has always trained very hard, but I did see a change in him in this training camp after the last fight. He has stepped up his training by two levels.
"He learned a lot about his fight against [Fidel Maldonado] under the bright SHOWTIME lights at the MGM Grand.
"Amir is always confident going into each fight, but he made a mistake in the Maldonado fight. He rolled his right hand and forgot about the left hand and was knocked down. He had to pay for his mistakes but it's all a learning experience, he still has only 16 professional fights under his belt.
"Castillo has a great jab and good combinations. A guy like that throws a lot of punches, but there is a technique to breaking down a fighter like that.
"We can't spend a lot of time on the ropes, and we must go after his body because his body is weak. Castillo is going to get knocked out on Saturday.
"I think that Amir is going to open up a lot of eyes on Saturday."
