Manny Pacquiao and Juan Manuel Marquez started their press tour today in Los Angeles at the Beverly Hills Hotel for their fourth fight which will take place December 8th. Both men have battled to three close fights before and hope to finally be able to close the chapter in their rivalry by giving the fans a definitive victory.

Pacquiao’s choice of opponent came down to Marquez and also a rematch with WBO Welterweight champion Timothy Bradley.  Bradley was awarded a controversial victory this past June over Pacquiao in a fight many thought Pacquiao had won.

Pacquiao spoke to BoxingScene and was asked why he decided to fight Marquez a fourth time and not pursue a rematch with Bradley and avenge his loss.

“I have nothing to prove against Bradley. Everyone saw who won the fight. If we fought it again it would be one sided” said Pacquiao to BoxingScene.com.

“I chose Marquez because we can give the fans a more exciting fight. I want to prove and remove any doubt anyone has.”

When Pacquiao was on the podium, he made insinuations that he would be looking to knock Marquez out this time by saying he didn’t want this fight to go “long”.

Another hot topic of discussion was Pacquiao arriving with 50 Cent to the press conference.

As BoxingScene had previously reported, 50 Cent is said to be working on a joint venture with Pacquiao to create their own promotional company which at one point Floyd Mayweather was also supposed to be a part of.

When BoxingScene asked Pacquiao to elaborate and talk about his deal with 50 cent, he wasn’t very willing to discuss any particulars.

“Right now we are just talking” would be the only thing Pacquiao would offer up.
