The pair of them will contest the vacant strap at the Theater at MGM National Harbor in Maryland.

Speaking at the press conference, Rodriguez said: “I’m more mature and experienced now than I was when I first won the title. I will be the fifth world champion from Puerto Rico right now and that would be a privilege. That’s the goal in this fight.

“I guarantee you I’m gonna come out with the win on Saturday, because I’m the toughest opponent he’s ever faced.

“I’m gonna prove I’m the best fighter in the division. This is gonna send a message to all the other champions that I’m here to stay.

“I’ve had so much love and support from Puerto Rico already. The island is eager to see me fight and I want to give back all that love with a win on Saturday night."

He then took a stab at predicting when victory would come, adding: “Starting in the fourth round, I should be able to figure out what he’s got in store for me. Then I feel like I can stop him between the fourth and seventh rounds.

“I’ve trained in Mexico and it’s been like a second home. They’ve really supported me. I owe it to all of them to give it my all.

“The fans are gonna see an amazing show and the best version of Emmanuel Rodriguez. I guarantee that.”

Lopez was similarly determined to claim victory.

He said: “Winning would bring me happiness and pride for my country, and it would prove to me that all my hard work ever since I was little, paid off.

“He can say whatever he wants, talk is cheap. Saturday night is where it’s all shown. He’s gonna have to back it up.

“I’m not gonna guarantee a knockout. I’m an animal that hunts for his prey. I’m gonna try to get him where I want and whatever happens, happens.

“He says he’s the best in the division, and he’s gonna try to show it. But I’m gonna do the same thing. I’m gonna try to show that I’m the best on Saturday night.

“I’m gonna give it my all for the world title. We both want it badly. For everyone watching on Saturday night, I’m gonna do everything I can to bring the title home.”
