Ignacio "Nacho" Beristain, was quoted in Primera Hora news as saying Manny Pacquiao will stop Miguel Cotto within six rounds. Beristain trained Juan Manuel Marquez for two fights with Pacquiao, and trained Oscar De La Hoya to face Pacquiao as well which gives him a unique perspective on a potential fight with Cotto.

According to "Nacho" Beristain Cotto has not been the same since he was knocked out by Antonio Margarito.  Read on to hear what he said…

Beristain told Primera Hora, "Cotto remained a little deteriorated after the fight that he had with Antonio Margarito and to be up against Manny Pacquiao, with all due respect - since I respect and I admire Puerto Rican boxing, but I believe that Pacquiao should put him on the canvas in five or six rounds".

"In the fight against Clottey, you could see some of the aftermath of what happened with Margarito. Clotty is not a top-level fighter and nevertheless, in some moments Cotto was put in predicaments and the punches were affecting him," Beristain said.

"Before he was a fighter with good technique, fast and well cared for, but he doesn't seem like himself. He changed his coach, changed some of his habits and catches more punches. I do not believe that it would very advisable to take a fight like this after changing his main trainer. A fight with Pacquiao is serious thing. You have to be well prepared. The fight with Pacquiao can be dangerous."
