Speaking in Doha, where he is visiting the AIBA World Boxing Championships, Pacquiao told AFP a final decision on who his last opponent will be, would be taken by "November or December".

The 36-year-old is on the verge of quitting boxing for politics and is likely to run for a seat in the Philippines senate next May. He also told AFP he would like to be the country's president if it is "God's will".

Pacquiao confirmed he is in negotiations with American Mayweather and Briton Khan but said he had no preference over who to fight. "I will fight anybody, anywhere," he said. "I am going to fight probably before the election.

"The election is coming next year, May, and before that I will probably have one fight."

He added: "We are going to finalise by November or December."

Mayweather actually retired with a perfect record of 49 wins and no defeats following his last fight, a near shut-out points victory over the overmatched Andre Berto in September.

However, very few people in boxing circles actually believe the brash and controversial Mayweather won't fight again.

Any potential fight would take place in March or early April next year, said Pacquiao, who also told Qatari broadcaster Al Jazeera that it could take place in the Gulf.

Pacquiao has been widely regarded as second only to Mayweather in the theoretical pound-for-pound rankings over the last few years.

He has 57 wins, two draws and six losses on his record over a 20-year career. The Filipino is in Qatar at the invitation of AIBA president, Ching-Kuo Wu, a personal friend.
