Manny Pacquiao and Floyd Mayweather Jr will have their long-awaited “mega-fight” tonight, and it’s expected to be watched by more pay-per-view viewers than any fight in history.

Five men who are among those expected to be watching it, are the five boxers which both Mayweather and Pacquiao have competed against in the past: Oscar De La Hoya, Ricky Hatton, Shane Mosley, Juan Manuel Marquez, and Miguel Cotto.

The five, who are all likely to be International Boxing Hall of Fame honorees, were interviewed at yesterday’s weigh-in event, where they offered their opinion on the bout.

Who has the advantage?

According to the four who agreed to offer an opinion: it’s “Money” in the bank.

“Mayweather has great experience, and great defense,” Marquez said. “He uses the counter-punch very well. He has more intelligence than Pacquiao. I think Mayweather wins this.” Marquez won a knockout victory over Pacquiao to avenge two earlier losses by decision. They also fought to a draw. He lost to Mayweather by decision in 2009.

Ricky Hatton suffered knockout losses to both men, but also sees the bout going Mayweather’s way: “I give Floyd the edge, because he can adapt to whatever style he is in against. I think he’ll adapt to Manny.”

Mosley, who lost to both by unanimous decision, said simply: “Mayweather has the speed and mobility to win. This could go either way, but my pick is definitely Mayweather.”

Of the four, Oscar De La Hoya expressed mixed feelings; saying “my head is with Mayweather, but my corazón (“heart”) is with Pacquiao!”

De La Hoya lost a split decision to Mayweather in 2007, and later lost to Pacquiao in what would be his final bout.

Cotto was the one fighter who refused to give a prediction. “I’m not going to pick a winner, because this is a tough fight… the guy who comes with no fear is going to be the winner.”
