Unified WBC, WBA and IBF world champion Jermell Charlo and his trainer Derrick James spoke with the press on Saturday at the kickoff press conference for Charlo’s battle against WBO world champion Brian Castano for undisputed status at super welterweight.

All four 154-pound belts hang in the balance for the first time in history on Saturday, July 17 in a Showtime televised main event from AT&T Center in San Antonio, Texas

Castano is currently deep in training, with a of of motivation to become an undisputed champion.

“I feel great, I’m having a great training camp and looking forward to stepping into the ring. This is the fight of my life and I feel so good about it," Castano said.

“This fight is such an honor and a privilege. To have the chance to unify the four belts is such a unique opportunity. It’s about making history. Only a few fighters have been able to achieve it and write a golden page in the history books of boxing. I plan to be the first Latino to do so.

“Fighting in San Antonio is quite big and everybody knows that Manu Ginobili is such a hero there. We all admire and love Manu, who is one of Argentina’s best-ever in any sport. If you go to San Antonio and you were born in Argentina like myself, you better be ready to give it your all to keep his legacy."

Castano has been reading a lot of comments from Charlo, who confidently predicts a spectacular win.

On the other hand, Castano is plotting to do a lot of damage in the ring. He does not believe Charlo will be able to deal with the onslaught.

“It’s going to be a tough fight between two great champions. Charlo is strong and a good boxer but he never suffered in the ring before. He will on July 17," Castano said.

“My prediction is that I am going to win and he will suffer.”
