Star Filipino pro boxer Manny Pacquiao is not yet done with Floyd Mayweather, the 37-year-old southpaw said. 

Pacquiao goes into the final fight of his pro boxing career on 9 April this year against Timothy Bradley, scheduled to take place at the MGM Grand Arena in Las Vegas. Pacman has himself announced that he will be retiring after the bout, but if there is a prospect of a rematch with Mayweather, retirement might be put off for the mega fight.

The year 2015 witnessed the "Fight of the Century" as two of the most decorated pro-boxers of recent times -- Mayweather and Pacquiao -- went head-to-head on 2 May at the MGM Grand Garden Arena. The fight shattered every single PPV (pay-per-view) record that existed.

The American Mayweather won the fight via an unanimous decision after 12 rounds of intense action in the ring, and as soon as the bout was over, boxing fans around the world started demanding a rematch.

Pacquiao, too, joined the chorus of a Mayweather-Pacquiao rematch. "I have been very vocal about it [fighting Mayweather] even before the Bradley fight was made official on New Year's eve," Pacquiao told "The reason is simple, I want to end my 21-year boxing career with a big bang so to speak.

"And what would be the biggest fight to end a career than fighting the best and finest boxer at least in this era?", Pacquiao, who till date remains the only boxer to win the championship title in as many as eight different weight divisions, added.

Pacquiao took the fight to Mayweather in the "Fight of the Century". The Philippines star remained more offensive, while Mayweather relied on his defensive tricks to score the points.

"We could have given that last May when we faced each other but due to unavoidable circumstances, sports fans failed to get the results they wanted," Pacquiao continued.

"Not that Floyd's legacy and mine can still be questioned but wouldn't it be more colorful and meaningful closing our respective careers on higher notes at the same time putting an end, too, on the business we started but we were unable to finish?"

Mayweather retired last year with a 49-0 record in pro boxing. His last fight was against Andre Berto in September. Pacquiao, meanwhile, is 57-6 in his pro boxing career.
