WBO welterweight champion Manny Pacquiao has again hinted at a money-spinning rematch against his long-time rival Floyd Mayweather. The 37-year-old Filipino took to his Instagram account to post a picture of the inside of his jacket, which features the faces of Pacquiao and Mayweather, and he captioned the post: "Like my jacket?"

The duo previously met in the ring in May 2015, when Mayweather won via a unanimous points decision. Since then, both men have announced their retirement from the sport, only for Pacquiao to return in a one-sided win against Jesse Vargas earlier this month, while Mayweather is also rumoured to be on the cusp of a comeback.

Mayweather, 39, was sat at ringside for Pacquaio's most-recent win at the Thomas & Mack centre in Las Vegas, fuelling rumours they were on the verge of agreeing to a second fight. And Pacquiao revealed after the Vargas win that the unbeaten Mayweather was at the fight at his request.

"If the rematch happens, I want to make sure the fans love it," Pacquiao recently told the Los Angeles Times. "I will give all I can to give my best to the fans. There's no discussions for now and that's not in my mind right now.

"Because we have this contact now, this can be easier to talk about if there's a rematch. Not only for myself, but if the fans in boxing want that rematch, then why not? We can easily talk about that. It's not a problem."

On the other hand, Bob Arum, Pacquiao's current promoter and Mayweather's former promoter, recently admitted he does not know if the much-discussed rematch will take place. Arum would be a central figure in any potential fight negotiations, but claimed to be in the dark about the bout being made.

"Do I know it's gonna happen? No. Do I know if Floyd wants the fight? No," Arum previously said. "I know nothing more than the public knows at this point and what I observed."
