Juan Manuel Márquez played down speculations that he will face Manny Pacquiao in a fifth fight if he wins in his upcoming bout against Mike Alvarado on May 17 at The Forum.

Márquez said in an interview with BoxingScene on Tuesday that he is not yet thinking about a fifth showdown with his Filipino nemesis, saying that he is focused on his upcoming fight against Alvarado.

"There is talk of a fifth fight, but I am not losing any sleep over it. I am preparing to fight against Alvarado and I don't care about any other fight," Márquez said.

The 40-year-old Mexican also added that boxing fans are not interested in a fifth fight, reiterating that fans want to see Pacquiao square off with Floyd Mayweather Jr. if the reigning pound-for-pound king defeats Marcos Maidana in their May 3 fight.

"I think the fight that the fans want is Manny and Floyd," Márquez said. "That's what they want to see and they should do it. I have already had four fights with Pacquiao, and many people would prefer to see these two opponents face each other in the ring. I think if we voted on what fight people want to see, I sure they would want to see Pacquiao vs Mayweather Jr."

Márquez turned down numerous offers to face Pacquiao again, insisting that he has no interest in facing Pacquiao after winning in their fourth showdown.

Márquez and Pacquiao engaged in three close fights before the Mexican boxing icon earned vindication after scoring a sixth round knockout win in December 2012.

Top Rank Promotions Bob Arum recently said that Márquez is now interested in facing Pacquiao because he wants to win the WBO welterweight title, which Pacquiao reclaimed in his recent win against Timothy Bradley.

However, Márquez sounded like he is leaning towards not facing Pacquiao again, and will likely follow the advice of his trainer, Nacho Beristáin, who recently said that a fifth showdown makes no sense.

"I do not like the fight, it is not attractive, and Juan did what he had to do, he showed how the Mexicans get it done, he showed his followers around the world who he is and that's enough," Beristáin said.
