WBC super flyweight champion Srisaket Sor Rungvisai declared yesterday he was ready to defend his title against Mexican Iran "MagnifiKO" Diaz at Bangkok's Muang Thong Thani on Saturday.

"After one of my toughest training, I am in tremendous shape and ready to defend my title. Performing in front of my fans here in Bangkok, and in front of all the Thai people, it is both an honour and a privilege for me," Srisaket told a press conference.

"I will do everything in my power to keep the belt and defeat a worthy opponent in Iran Diaz. I know he's ready too, and I am prepared for whatever he brings to the table."

It will be the main bout of the ONE: Kingdom of Heroes, which also features several MMA fights.

The event will be shown live on Thai Rath TV and Workpoint from 9.30pm.

"Right now, the time for talk is over. It's time to lace up the gloves and prove ourselves inside the ring. I will do my best to give the performance of a lifetime. Everyone who is a fan of boxing should tune in, because we are going to do something special this Saturday night," Srisaket said.

"I would like to thank ONE Championship for the opportunity to participate in such a massive event."

The 31-year-old champion has a 46-4-1 (41KOs) record.

Diaz said: "I have never trained harder. This is the most important fight of my career. I am proud to be in the best shape of my life, and I am 100 percent ready to step on the champion's home soil and score an upset.

"I know that he is a very powerful and aggressive puncher, but I am confident in the strategy my team and I have come up with. He's a superhero in Thailand, but I'm going to crash this party and take the title here on his home soil.

"Get ready for the biggest upset of the year. I'm heading into this fight fully expecting to walk away with the belt around my waist as the new champion. I know it's not going to be easy, but I will do whatever it takes to emerge with the win.

"It's going to be an amazing fight this Saturday night. I'm coming into hostile territory, but I'm packing the firepower. Let's get ready to rumble."

The 28-year-old Mexican has a record of 14-2-3 (6KOs).
