Motivation has never been a problem within Sergio "Maravilla" Martinez's team. But for the fight against Miguel Cotto (38-4, 31KOs), the Argentine boxer is pushing himself to make a clear statement that he can still compete at a high level despite the fact that he is 39 years of age. Martinez will return, after healing several injuries, for the first time since beating Martin Murray last April in Argentina.

"I truly believe that Sergio will win this fight by knockout. This is the fight that Sergio has wanted for some time. So he is working with enthusiasm and motivated to prove he is still the best,” said his trainer Pablo Sarmiento

Martínez began training Madrid, Spain and then moved to Miami where he has been training.

“Sergio is going to be 100% when he faces Cotto. We’re doing many things and Sergio has been improving his speed. Everything is going as planned, and we have plenty of time to keep working,” he said.

Martinez (51-2-2, 28KOs) will have the biggest fight of his career when he defends his WBC middleweight title against Cotto on June 7th at Madison Square Garden in New York.
