May 2 showdown between Pacquiao and Hatton is on heat.

Manny Pacquiao of the Philippines insists there is no Hatton deal to the much talked boxing match against Ricky Hatton.

Hatton of England remains uncertain as the Pacquiao camp takes a hard line stance on their demand for a bigger share of the revenue pie.

In a statement from Pacquiao adviser and friend Rex Wakee Salud 'Manny's stand is the same, he is not fighting unless the numbers moved to his favor.

Pacquiao is demanding 60 percent of fight and pay-per-view purses, a sharing that does not sit well with the sluggers' Hatton camp.

Salud's statement conflicted with Pacquiao's promoter Bob Arum, who claimed Wednesday that the fight is back on track after Pacquiao was promised half of the PPV revenue in Britain, where Hatton has a huge following.

Bob Arum of Top Rank Promotions said that Manny has agreed on the 50-50 sharing arrangement after he explained the reasons why he should agree and after assuring him that he won't be disadvantaged with the arrangement.

'Manny doesn't understand that this is a fight that he's never been before. If he is firm about the 50-40, then the fight is not happening, Arum said.

The camp of Ricky Hatton threatened to sue Manny Pacquiao if the Filipino ring icon backtracks on a verbal agreement for a 50-50 split from the revenues.

We had all this before Christmas when they were talking about different figures and we agreed a 50-50 split with them, said Hatton lawyer Gareth Williams.
