Manny Pacquiao is "not surprised" the World Boxing Organization affirmed the loss of his welterweight title to Australian Jeff Horn, but the Philippine ring legend railed at large at judges who "manipulated results".

The WBO ordered a review of the scoring of the July 2 Brisbane bout at the request of the Philippines' Games and Amusements Board, which criticised the judges and the referee.

The WBO set up a panel of independent and anonymous judges to watch and score a recording of the bout without sound. On Tuesday it said the judges found Horn won seven rounds to Pacquiao's five.

"We have seen worse Judgments in the past where judges manipulated results. Nothing surprises me now," Pacquiao said in a statement late Tuesday.

He did not name the judges nor mention the specific fights in his allegations.

"Let the people judge for themselves. People saw what happened," said the 38-year-old, who had won world titles in an unprecedented eight weight divisions.

The undefeated but unheralded Horn, 29, had stunned the Filipino legend with his ultra-aggressiveness to earn a unanimous decision.

But the Filipino's camp alleged the referee let the Australian get away with illegal tactics.

The WBO ordered the review while stressing it did not have the power to reverse a decision unless fraud or legal violations were proven.

Pacquiao had endorsed the call for a review issued by the Filipino sports regulator, which lashed out at the "unfair decision and officiating" of the fight.

In a statement sent to AFP on Wednesday, the Filipino regulator thanked the WBO for looking into the fight but blamed American referee Mark Nelson for the results.

"No matter what review they do, it will be hard to change the result as the referee didn't call it close," said board chairman Abraham Kahlil Mitra.

"The judges' scores would have greatly changed if the referee did his job properly," Mitra alleged.

"He (referee) didn't give Senator Manny Pacquiao the respect and fair protection that is due to a people's champ," Mitra said, referring to Pacquiao's elected post as a Philippine senator.

Horn, a former schoolteacher written off before the bout by most observers, welcomed on Tuesday the ruling as "evidence" of his victory.

"It's definitely nice to have it finally put on paper," said Horn, who had been keen for a rematch.

In the twilight of a 22-year pro career, Pacquiao had initially called for a Horn rematch, but later said he would also "think hard" about retiring.

Pacquiao briefly quit boxing last year to pursue his long-held political ambitions and was elected senator. But he quickly made a successful comeback against Jessie Vargas in November, saying he still felt like a youngster.

Pacquiao's loss to Horn had prompted calls urging him to retire for good.

Pacquiao also issued a separate statement on Wednesday denying news reports that he had failed to pay his US trainer Freddie Roach.

"I have no problem with coach Freddie Roach. I'm not the one paying him, it's Bob Arum," Pacquiao said, adding that he was also waiting to be paid by the owner of US fight promotions firm Top Rank.

"The trainer's fee is automatically deducted by the Top Rank from my purse. So if coach Freddie has not yet received his payment, we are on the same boat," Pacquiao said.

Press reports on Tuesday quoted Roach as saying that he had not spoken to his boxer since the Horn defeat, and that he had not been paid for the fight.

"Not true," a member of Pacquiao's team told AFP Wednesday when asked if the boxer was avoiding Roach, adding Pacquiao was "surprised why such kind of news came out".
