Trainer Nacho Beristain, who works with former four division world champion Juan Manuel Marquez (56-7-1, 40KOs), has no problem with an immediate fight against Miguel Cotto (40-5, 33KOs).

The idea of the fight first came about when Cotto's trainer, Freddie Roach, called Marquez 'the perfect opponent' for the Puerto Rican star's next return.

Marquez, 42-years-old, has been out of the ring since a May 2014 twelve round decision victory over Mike Alvarado. The boxer had planned several return dates, but he was never able to get them in place due to an ongoing issue with his knee.

With nearly two years of inactivity, Nacho says a fighter like Marquez would not require any tuneups - he can hit training camp and go straight into a Cotto fight.

"[Marquez] has never closed the door [on fighting again] and he's made no decision to retire from boxing," Nacho told Fox Deportes. "I have not spoken with Juan Manuel for three months, but I know him and he's never had any problems with inactivity. He can still return straight to training."

"I do not rule out [this version of Marquez] being capable of fighting against Cotto. If [Marquez] returns to the ring, I don't think it is unreasonable to do it with an opponent of that level. It would be a good fight, given their styles."

Cotto was in the ring last November, when he lost a twelve round unanimous decision to Saul "Canelo" Alvarez.

Roach says his fighter can still get down to 147-pounds. Cotto came in at 153.5 [below the junior middleweight limit] for two of his three middleweight fights. Marquez has never weighed higher than 144.5 for any of his welterweight fights.
