MANILA, Philippines – Mexican boxer Juan Manuel Marquez welcomes the opportunity to win another world championship in a fifth weight division, most likely at welterweight.

Marquez has already won world titles in four different weight divisions but he said in an interview with Boxing Scene that he wants to go for a fifth.

“Why not? It would be wonderful to win another championship,” said the Mexican boxer.

A potential target is the World Boxing Organization (WBO) welterweight title, currently being held by unbeaten American Timothy Bradley.

“Of course, (the WBO title) would be a possibility.... That title, I already won it in 2011 against (Manny) Pacquiao, but the judges denied me,” he said.

The WBO welterweight belt was on the line when Marquez fought Pacquiao for the third time in November 2011, but he lost via a controversial majority decision. No belts were on the line when Marquez knocked out Pacquiao in their fourth fight last December 2012.

“If we continue boxing, of course I would be thinking about winning a fifth championship,” said Marquez.

But the Mexican said he is focused on his family and has yet to decide on his future on the sport.

“I was invited to watch the Bradley fight, but I spent this weekend with my family,” he said.

It was earlier reported that Marquez has opted to continue his boxing career after considering retirement following his win over Pacquiao.
