WBO welterweight champion Manny Pacquiao is slated to return on April 22nd, in a fight with undefeated 2012 Australian Olympian Jeff Horn (16-0-1, 11 KOs).

Pacquiao's promoter, Bob Arum of Top Rank, will be meeting with the boxer in the coming days to finalize the financial terms for the contest - which is likely to take place in Australia.

While the fight is unlikely to take place, Pacquiao is still fixated on the possibility of facing Floyd Mayweather Jr. (49-0, 26 KOs) in a rematch. Mayweather retired from the sport in September 2015 after winning a twelve round decision over Andre Berto.

In May 2015, Pacquiao lost a twelve round unanimous decision to Mayweather. It was the most lucrative fight in boxing history with 4.6 million pay-per-view buys and $600 million in revenue.

Pacquiao felt that he won the contest by at least "two or three rounds." He feels the boxing public is on his side and view him as the rightful winner.

“I only lost in the eye of the judges, in the eyes of the people I didn’t lose,” Pacquiao said to Fox Sports.

The Filipino star is claiming that his performance would have been more dominant - if he hadn't suffered a right shoulder injury during the fight.

“It just happened that third or fourth round I injured my right shoulder,” Pacquiao said. “I felt like I have only one arm but thank God that I survived until 12 rounds.”

At 38-years-old, Pacquiao (59-6-2) is getting closer to the end of his Hall of Fame career. How long will he continue? He could see himself fighting for another two years - and having another three to four fights before retiring for good.

“My age 38, I don’t believe that I’m old. I still feel I’m young and I work hard. I work hard in the ring,” Pacquiao said. "I discipline myself. I can still do that, so I believe that I’m not old aged like they are thinking about. I believe Manny Pacquiao is still good for two years in boxing. (How many fights) depends, maybe three or four more”
