Boxer Manny Pacquiao was impressed by Floyd Mayweather's win over Miguel Cotto on May 5, but still doubts that the two fighters will ever meet up in a ring.

When he offered me only $40 million, I knew he didn't want the fight, Pacquiao told the Los Angeles Times about Mayweather's offer of pay-per-view cut of the fight. And when he says the fight will never happen now, that's because he doesn't want the fight.

I'm hoping the fight will happen. I'm willing to meet him face to face.

Fans have longed for the two dominant fighters to meet in the ring, but time after time some issue pops up to derail any chance of it actually happening.

Mayweather has long demanded that Pacquiao undergo additional drug testing, but some have long believed that he doesn't want to risk his unbeaten record against the Filipino fighter. Mayweather told reporters after his win over Cotto that a fight against Pacquiao wasn't going to happen, but that it wasn't his fault.

Both fighters seem in agreement that a fight won't happen, though some in the boxing industry remain optimistic that a fight would eventually happen.

Golden Boy Promotions CEO Richard Schaefer recently told the Telegraph that the two will eventually fight each other, but it likely won't happen this year. Mayweather's uncle, Roger, backed up that idea when he told reporters in 2011 that a fight would eventually happen in 2013.

One major reason why fans think that a fight will eventually happen is all of the potential money that the fight would generate. The recent Mayweather-Cotto fight generated 1.5 million pay-per-view buys, according to HBO, and a Mayweather-Pacquiao fight would easily surpass those numbers.

Pacquaio's next fight is against 28-year-old Tim Bradley on June 9, while Mayweather begins a 90-day jail sentence next month.
