Muhammad Ali for Manny Pacquiao...

Muhammad Ali has shunned his compatriot Floyd Mayweather to support Manny Pacquiao in the long-awaited superfight on May 2, with his daughter hinting that Ali is less-than-impressed with Mayweather's lifestyle out of the ring.

"My dad is Team Pacquiao all the way! My dad stood for things,” Rasheda Ali said. “Mayweather ... I don’t think there’s a comparison.”

"My dad really likes Manny. He's a huge fan of his," she told TMZ. "He knows Manny's a great fighter ... but it's more about what he does outside the ring. He's such a charitable person."

Pacquaio channels much of his earnings into helping the poor in the Philippines and is increasingly involved in politics in his home country, whereas Mayweather is renowned for flaunting his wealth on social media.

The Filipino's preparations for the bout, which takes place at the MGM Grand in Las Vegas, have been hit by his receiving a £33million tax bill for outstanding owings from 2008 and 2009.

He will be able to pay that bill in one fell swoop after the fight, however, as he is expected to earn £54million to Mayweather's £80million from the pay-per-view event.

Ali will be one of those contributing to the coffers - the former world heavyweight champion regarded by many as boxing's best-ever fighter, will be watching at home, the 73-year-old's Parkinson's Disease preventing his attending the fight.

"There's no question he's going to order it," said Rasheda Ali. "It takes my dad way back to when he was fighting."
