While Manny Pacquiao is open to a rematch with Floyd Mayweather Jr., Adrien Broner has second thoughts on the possibility.

Manny Pacquiao (60-7-2, 39 KOs) will put his WBA welterweight secondary title on the line when he faces Adrien Broner (33-3-1, 24 KOs) at the MGM Grand Arena is Las Vegas on Jan. 19. It appears that Floyd Mayweather Jr.’s name will be brought up constantly in the build up to the fight.

“If he (Mayweather) comes out of his retirement, let’s see,” Pacquiao said. “We’ll see after this fight, but we can not underestimate Adrien Broner. We can not underestimate this fight because I have to go through this fight first before we talk about and discuss the rematch with Floyd Mayweather.”

There is speculation that a rematch between Pacquiao and Mayweather can happen in 2019. In September, Mayweather and Pacquiao spoke about a rematch after they met during a music festival in Tokyo. Then in October, Pacquiao left Top Rank and signed with Al Haymon, the founder of Premiere Boxing Champions; and longtime adviser of Mayweather.

While Pacquiao addressed the idea of a potential rematch with Mayweather, Broner wasn’t too happy with the talk about future fight plans.

“Man, f–k Floyd,” said Broner. “No disrespect, but he ain’t fighting Floyd; he fighting me. I’m about to beat yo m—–f—–g ass man and you worrying about Floyd? He (Floyd) already beat you brother.”

Mayweather (50-0, 27 KOs)  has also expressed interest for a rematch with Pacquiao in 2019, after a December tune-up fight. He is due to fight Japanese kickboxer Tenshin Nashukawa (27-0) in a three-round boxing exhibition in Japan on Dec. 31st.

Pacquiao and Mayweather first met in the ring in May 2015, a fight that shattered all-time boxing revenue records with an estiamted 4.6 million PPV buys, over $400 million in domestic PPV revenue; and a live gate of about $72 million. Mayweather went on to defeat Pacquiao by unanimous decision.
