After officially announcing their fourth bout Tuesday, Manny Pacquiao and Juan Manuel Marquez began promoting their Dec. 8 welterweight fight taking place at the MGM Grand Garden Arena in Las Vegas.

In an interview on ESPN’s “SportsCenter” Thursday, Pacquiao and Marquez sat next to each other and answered questions in studio, and some of them revolved around Floyd Mayweather Jr.

Pacquiao was asked about a possible fight with Mayweather Jr. in what could be a $120 million bout.

The 33-year-old Filipino star seemed frustrated with the question, and suggested that he doesn’t know the hold up and is “eager” for the fight. Pacquiao claims that he will accept a smaller percentage of the purse, and will commit to all drug-testing demands.

“I’m hoping for next year,” Pacquiao said. “I’m not running from him, maybe he is scared of me.”

As for Pacquiao-Marquez IV, both boxers want a clear ending to their rivalry. In their last two bouts, Pacquiao won on decisions, and many believed Marquez should have won their most recent one in November, despite Pacquiao landing more total punches and power punches.

“I want this fight because a lot of people in the Philippines and in Mexico want this fight,” Marquez said. “I think I won the last two fights. They were close and I am ready for this fight.

“The last fight? I feel very angry. ”

Marquez stated that despite the decision he is “a professional.” At 54-6 for his career, the Mexican national said he will have to challenge himself and change up his approach in their next meeting, as both he and Pacquiao know each other’s styles too well.

Pacquiao acknowledged the criticism that he is too nice, but that he is different when the action gets started. He also indicated his need for a resounding, unquestionable win.

“I’m very friendly,” said Pacquiao. “Sometimes I bring that in the ring. I need to get back aggressiveness and I want an impressive win.”

Pacquiao has 39 career knockouts, but has failed to record one in his last five matches. He managed a technical knockout against Miguel Coto in November 2009, and before that sent Ricky Hatton to the mat in May of the same year.

Mired in controversy in his last two bouts, Pacquiao was also considering a rematch with American Timothy Bradley, who won a split decision in June for the WBO welterweight title. Despite that questionable ending, a fourth meeting with Marquez has a much bigger draw and the potential for more lucrative pay-per-view sales.
