World Boxing Association (WBA) welterweight champion Manny Pacquiao has hit back at Floyd Mayweather for his statements in a recent interview.

Mayweather won a twelve round unanimous decision over Pacquiao in May of 2015, in what was the most financially successful pay-per-view event in history.

Mayweather, 43-years-old, retired back in August 2017, when he stopped UFC superstar Conor McGregor in a cross-sports boxing match.

Pacquiao, 41-years-old, is still going strong in the welterweight division.

His last fight took place in July of 2019, when he turned back the clock to win a twelve round decision over Keith Thurman to capture the WBA title.

Most of the top contenders at 147-pounds  - like Errol Spence, Terence Crawford, Thurman, Danny Garcia - are calling for a fight with Pacquiao.

Mayweather believes they should focus on fighting each other instead of chasing after the "old man." 

“It’s sad that you hear guys say, ‘I want to fight Manny Pacquiao.' But Manny Pacquiao is 41 now. Don’t chase him. You young guys chase each other. Stop chasing this old man. If the opportunity presents itself, go out and do what you got to do. Let Manny Pacquiao pick and choose who he wants to fight,” Mayweather told Fighthype.com.

According to Pacquiao, his career rival is simply displaying an envious nature.

"Mayweather Jr, he is just envious because he’s already retired. We’re still active and have a crown,” Pacquiao told The Manila Times.

The eight division world champion is planning to fight again once the coronaviris pandemic begins to slow down and sporting events are allowed to have spectators.

“Yes, I’m okay. No plans yet; no problem. Actually, I just finished hitting the punching bag. No retirement yet. Yes, I’m still training. God is good all the time,” Pacquiao revealed.
