Manny Pacquiao will go down as one of the greatest fighters of all time and newly crowned world heavyweight champion Oleksandr Usyk possesses a similar skillset, says Joseph Parker.

Pacquiao's decorated boxing career has come to an end, with the sport's only eight-division world champion announcing his retirement.

His decision came under a month after his unanimous points loss to Yordenis Ugas for the WBA super welterweight title.

The 42-year-old had made his boxing return against Ugas for the first time since July 2019, but the Filipino's comeback did not go according to plan in Las Vegas.

Pacquiao, who has declared his candidacy in the 2022 Philippine presidential election, retires with a record of 62 wins (39 knockouts), eight losses and two draws.

Heavyweight contender Parker, who was speaking prior to the formal announcement from Pacquiao, suggested he did not want to see one of the best boxers in history fight on. 

He also thinks Usyk, who has just been crowned WBA, WBO and IBF champion after defeating Anthony Joshua, possesses some of the same traits.

"I feel like he's going to go down as one of the best of all time," New Zealander Parker said to Stats Perform.

"It is quite hard to see someone like Pacquiao to continue to fight when he had this great legacy and great career. 

"And now he can still beat a lot of guys but it is hard to see someone who is not in his prime. They keep fighting and let these guys get the better of them."

Describing what makes Pacquiao special, Parker added: "I feel like he is similar to [Usyk]; his movement, his footwork; he's very quick on his feet and also the volume of punches that he throws. 

"He throws a lot of punches and combinations. 

"And I feel like it's really hard to fight someone like Pacquiao when he's trying throwing all these punches and the movement that he presents.

"His legacy? The eight-time division champion - just the achievement of that and a lot of a lot of young fighters look up to him. 

"You have to say that he's going to go down in history and he's going to always be talked about, as an eight-time division world champion. 

"And he can give a lot back to the sport by teaching the [young] fighters, signing other fighters and just being involved as a manager or promoter, as he knows the game and set up.

"My favourite Pacquiao fight? I really like the fight against Ricky Hatton. Just the timing and precision of when he landed the big shot to finish the fight. 

"Hatton is a beast himself and has had a great career, but when you’re in the ring with Manny Pacquiao it’s a different story."
