Bob Arum says Manny Pacquiao needs to look elsewhere to promote his upcoming rematch with Floyd Mayweather -- telling TMZ Sports, "I don't want any part of it."
The Top Rank boxing chairman -- who was a key part of the original Mayweather vs. Pacquiao fight back in 2015 -- has said his deal with Manny expired and the boxer is essentially a free agent who can sign anywhere.
But, Arum says ... even if Manny asks him to come back and do it again, he's 100% out.
"They're past their prime. It'll do good at the box office. It'll make money, which is fine. But, they're not elite fighters anymore."
"It's a money grab. Business is business. It's good money for each of them. You can't begrudge them, but they're not elite anymore."
Remember, the original fight is the best-selling combat sports Pay-Per-View event of all time -- with more than 4.6 million buys.
As for the rematch, Floyd and Manny have teased a possible December date for the clash -- and Showtime Sports says Floyd's "deadly serious" about making it happen.
