Four division world champion Erik Morales, who is the trainer of Tijuana’s Angel Fierro, is days away from his fighter’s matchup against Puerto Rico’s Alberto Machado - which is Thursday night’s Ring City USA main event.

The fight takes place at the Albergue Olimpico (Olympic Center) in Salinas, P.R., and live on NBC Sports Network (9 p.m. ET/6 p.m. PT).

Morales will not be working the corner, with assistant trainer Fernando Fernandez handling those duties.

“Fierro is always working, always training. He was training to fight a guy very similar to Alberto Machado. Fierro is a fighter worth watching. He’s clean, young and strong. He’s going to give the fans a great fight on Thursday. He is a fighter who fights very well at a distance. He also throws very hard and when he’s throwing punches in bunches, you will see why we took this fight," Morales said.

“We have been working together for 3 or 4 fights. Sometimes we rotate fighters in our gym because we can’t train them all. It’s been about a year. Fernando Fernandez has been training with me and other fighters with me since 1998 so he is in good hands.

“[Angel] has learned a lot with us. When we got him, he used to jump a lot. But now he is better in his offense. He is a great fighter who is very tough. He is very strong. There are opportunities that don’t come very often. We lost a fight last time that we weren’t supposed to. But in this fight, he has an opportunity that he has to take advantage of, and he will. You’ll see him make the most of it on Thursday.”

Morales then gave his take on several other topics, like this past Saturday's rematch war between Juan Francisco Estrada and Roman 'Chocolatito' Gonzalez.

“It was an interesting fight. Both fighters were active. The 117-111 card was off but the other two were good. It’s been a while since we’ve seen such a great, phenomenal fight," Morales said.

And Morales is backing his former trilogy foe, Manny Pacquiao, to beat Mikey Garcia, if the two boxers end up facing each other in the coming months.

“Mikey Garcia is a great fighter. Manny Pacquiao is very, very strong though. Pacquiao shows that there are levels to this game. I think that experience will win out and Pacquiao wins," Morales said.
