Hall of Famer and former world champion, Sugar Ray Leonard, believes Floyd Mayweather should come out of retirement and face career rival Manny Pacquiao in a rematch.
The two boxers collided back in May of 2015, with Mayweather walking away with a twelve round unanimous decision.
The bout, which took several years to finalize, became the most financially lucrative contest in the history of the sport.
Mayweather, 42-years-old, retired back in August of 2017, when he stopped UFC superstar Conor McGregor in ten rounds at the T-Mobile Arena in Las Vegas.
Pacquiao, 40-years-old, has continued to fight on. Last month, he showed glimpses of his prime when he dropped and decisioned undefeated Keith Thurman to capture the WBA welterweight title at Las Vegas' MGM Grand.
Pacquiao has continued to call for a rematch with Mayweather. He claims to have entered the first bout with pre-existing shoulder injury, which sustained further injury during the fourth round. Whether or not the shoulder affected his performance is up for debate, but he underwent surgery a few days after the fight.
Mayweather's last ring appearance was a New Year's Eve exhibition bout in Japan, where he demolished featherweight kickboxing star Tenshin Nasukawa in the first round.
Leonard would like to see a second fight take place. He expects the rematch to sell - and he also expects most of the critics to watch the fight.
"Put it this way, it should be done. People will watch it," Leonard told TMZ.
"It's two guys in their 40s. When I was 40, I came back, I don't know who it was against, but you had a different stage in your life, spiritually, physically, mentally. He (Pacquiao) looked phenomenal (in his last fight)."
