"I'm happy to be back here in Chicago. [Ngumbu] is a good fighter who should give me a tough fight, but I'm going to walk out the champion.
"I can't wait to go in there and give the fans what they want to see - a good, tough fight.
"I'm going to box him a bit and use my jab, but if the knockout comes then I'm going to take it.
"I want another shot at a world title, but I have to beat this guy first and keep winning until I get another chance. I feel that I'm ready for another shot, but this guy stands in my way on Saturday."
"This is a great opportunity for me and a great honor to fight on American soil. I trained hard to be perfectly fit for this fight and my opponent.
"It's not a secret that Fonfara is a powerful puncher, but I'm not worried it. What happens in the ring on Saturday is the only thing that really matters. I'm not worried and I'm certainly not scared. I'm confident I have what it takes to defeat him.
"I did everything that I had to do while in training camp. I've trained very hard. And now I'm here to show the world that working hard pays off.
"I came all the way here to do one thing: win."
"It's my second time fighting here in the U.S. and I'm very excited to defend my belt again here.
"I'm Japanese, but I live in Mexico. I fight like a Mexican. Boxing fans better be ready, because Saturday night is going to be a true all-Mexican brawl.
"This is a fight for Japan, a fight for Mexico, a fight for all the Latinos. I respect my opponent a lot, but there is a reason I'm undefeated, there is a reason I'm the champion and I'm going to win the fight.
"We're going to scream ‘Viva Japan,' we're going to scream ‘Viva Mexico' and ‘Viva los Latinos' for all the fans in the U.S.
"On Nov. 1, you are going to seem me eat up ‘The Little Clown.'
"No question, I'll be looking for a knockout. There's no other way to go."
"I'm going to take advantage of this opportunity to become a world champion. I'm ready to show that I'm the champion, not him.
"Tomoki is a good fighter. He's fast and slick, but I am, too. I know his style, he's predictable, and I'm ready to fight and take that belt away from him.
"He's not a real Mexican. He wants to be a Mexican, but he's Japanese. I'm the real Mexican here. I'm so Mexican that even the dirt under my fingernails is Mexican. Tomoki is Japanese, and he came to my country to learn from us, the Mexicans. But let's not forget who the real Mexican is here.
"He comes here saying he represents Mexico and he's not even Mexican. I don't have to pretend. I'm 100 percent pure Mexican blood.
"I have my game plan ready. I've trained hard and I know exactly what I'm going to do in the ring -- how I'm going to move, what type of punches I'm going to throw. I'm ready. This is my chance to shine and I'm not about to let it go.
"On Saturday night, I will win. I'll be a world champion, a true Mexican champion."
"I'm not really worried about him. I prepared very well and I hope he trained well, too. I don't want any excuses when he lands on the floor this Saturday.
"He's a good fighter and he has a good trainer, but he hasn't faced anyone like me.
"He may have faced Dominicans before, but that was in the amateurs. It will be a lot different now that he's a professional, and it will be a lot different when he gets in the ring with me.
"I have faced better fighters in my career than he has, no question.
"I'm not looking for the knockout, but if I connect a few punches and I see he's hurt, I'll just go for it. I'm going to work him. This is going to be the end of Abner Cotto.
"I studied Abner Cotto very well. Day after day and night after night, I studied him throughout training camp with my trainer, Hector Bermudez. I studied his strengths and his weaknesses. I've learned his ways, I learned everything about him and I'm ready to defeat him.
"At 130 or 135 pounds, wherever I see the opportunity to get a world championship, I'm going to seize it."
"It won't be an easy fight, but I'm going to do everything I can to make sure it doesn't go the distance.
"I've faced Dominican fighters before so I'm not worried about him or his power. Beating Fortuna is an opportunity to put myself in the top three in the division.
"I hope he comes ready and we can give the fans a good fight. I know I'm ready.
"I have faced some of the best fighters in the world in this division. Fortuna doesn't intimidate me, he doesn't bring anything that I haven't seen before.
"Some people say that Fortuna is very powerful and I that should be very careful, but I'm not thinking about that. I'm only focused on the power in my punches. I'm not going to let them get into my head.
"My Puerto Rican fans better be ready. I'm going to deliver on Nov. 1 and I'm going to make them very proud. I'll put up a great show. I've had plenty of hard fights, tests and challenges and I've overcome them. On Saturday, my fans are going to see a different Abner Cotto.
"The key for my victory lies on being smart, patient and taking advantage of every opportunity that comes my way. I plan on exploiting every little mistake that Fortuna makes."
