Manny Pacquiao said on Friday there are "serious negotiations" ongoing between Floyd Mayweather's camp and Pacquiao's promoter, Bob Arum, for a $300 million fight in 2015, Martin Domin of the Daily Mail reported.
The welterweight champions have been unable to come to an agreement on a fight numerous times in the past.
The 35-year-old Pacquiao (56-5-2, 38 KOs) and 37-year-old Mayweather (46-0, 26 KOs) are considered two of the best pound-for-pound fighters in the world. The fight is expected to be the richest in history.
Pacquiao said the fight would be "probably for next year," and Arum recently said there could be two fights between them in 2015.
"All signs seem to point to a first fight early next year," Arum said.
Pacquiao's comments came during a press tour to promote his fight with Chris Algieri in November.
Pacquiao has said he plans to retire in 2016 to devote his time to politics in his native Philippines.
Mayweather, who has a rematch with Marcos Maidana in Las Vegas next Saturday, has three fights left on a six-fight, $200 million deal with Showtime, with the last two fights expected to be in May and September of next year, according to the Daily Mail.
