MEXICO CITY -- Hall of Famer Nacho Beristain says he believes Canelo Alvarez should beat Amir Khan on May 7 because he is a good fighter, has the tools and he will have a big weight advantage on the day of the fight.

But that did not stop the renowned Mexican trainer from guaranteeing that the fight will be "high voltage."

"I think it's a very good combination," Beristain said. "In a way, it's a great opportunity for Canelo to prove to people that he has something. For me, he lost the fight with [Miguel] Cotto and this is a great opportunity to put on a display, because the Englishman is a good boxer, an excellent boxer. The fight may be short but it'll be high voltage."

While both are fighters are strong from a technical standpoint, Beristain says each one will enter the ring with a clear physical advantage.

"Canelo is very strong; he'll weigh 155 pounds on the day of the weigh-in, and about 170 on the day of the fight," Beristain said. "Khan's advantage is speed and that could end up hurting Canelo.

"The good thing here for Canelo is that Khan doesn't have [Floyd] Mayweather's defensive style. Khan likes to put on a show which means the fight will be spectacular."

Beristain said he was hoping for an Alvarez knockout but that the fight would be high quality and action-packed, however long it lasts.

"It will be a great fight, however long it lasts, including the build-up and the press conferences," Beristain said. "Khan's British fans are as passionate as Mexican fans and Khan knows he can't let them down."

Beristain also says he believes Alvarez should look to put on a show, because most people expected more from him against Cotto and he failed to live up to expectations.

"I think Canelo has everything in place to put on a show," Beristain said. "I think it'll be sensational from the moment the bell rings and hopefully Canelo can take this opportunity to regain his credibility with people. I like how he fights, he has good skills. I don't know why it has been so tough for him."
