Manny Pacquiao has once again underlined his intention to fight Floyd Mayweather Jr before he hangs up his gloves.

Pacquiao is set to defend his WBO title against Chris Algieri in Macau on 22 November but the build up to that contest has inevitably been dominated by more speculation over a long-awaited showdown between the two welterweight kings.

Mayweather, 37, has repeatedly dismissed talk of ongoing negotiations for a fight in 2015 and has done little to suggest he is ready to sit down and discuss a deal with Pacquiao's promoter's Top Rank.

With the unbeaten American considering retirement in September 2015, Pacquiao and his representatives have a deadline hanging over them although Mayweather's most recent comments suggest he is considering extending his current deal with Showtime.

While the five weight world champion mulls over his future, the Filipino admits it is frustrating trying to negotiate when "you are the only one sitting at the table" but still harbours hope of seeing an agreement met with no plans to step away from the ring himself on the horizon yet.

"As long as my skills and my passion remain strong I want to continue my boxing career," Pacquaio was quoted as saying by Boxing Scene. "When I retire, I want it to be on my terms. I do not want to spend my retirement regretting that I walked away from boxing before I was ready. I do not want to come back and fight after I retire.

"My goals are to finish as a world champion, winning my remaining fights. Since the last Marquez fight [his last defeat in December 2012] I have approached every training camp and every opponent with 110% dedication. I would like to keep challenging myself in the opponents I will face in the future.

"I have not set a date or determined an age when I will retire. As long as I can keep fighting at the level I expect from myself I will continue my boxing career.

"I do have one specific goal and that is to give the boxing fans the fight they have always asked for [with Floyd Mayweather Jr]. I want that fight too. I believe good faith negotiations could produce that night. But it is impossible to negotiate when you are the only one sitting at the table. Two fighters who want to fight each other have never been kept from fighting each other."

Mayweather has just two fights remaining in his current Showtime contract which will take place in April and September next year, but recently hinted he may put plans to retire next year on hold to prolong his career in the ring.
