Shane Mosley is eyeing another crack at Manny Pacquiao, Miguel Cotto and Floyd Mayweather after his upcoming fight against David Avanesyan on May 28 at Gila River Arena in Glendale, Arizona.

Mosley, who owns a 49-9-1 record with 41 knockout victories, is looking for his third straight knockout win, saying that he is determined to prove his doubters wrong and get a chance to face his former tormentors.

The 44-year-old former world champion, who is coming off knockout victories against Ricardo Mayorga and Patrick Lopez, said that he has unfinished business with Pacquiao, Cotto and Mayweather.

"Like I said before, I want a Pacquiao rematch. A rematch with Mayweather and a rematch with Cotto," Mosley said via BoxingScene.

Mosley took a unanimous decision loss to a then-unbeaten Cotto in November 2007. He then challenged Mayweather in 2010, but the former pound-for-pound king ran away with a lopsided decision win in their showdown. One year after losing to Mayweather, Mosley absorbed a unanimous decision loss to Pacquiao in May 2011.

However, both Mayweather and Pacquiao have already announced their retirement. Mayweather decided to call it quits after winning against Andre Berto in September, while Pacquiao said that he will not fight again following his unanimous decision win over Timothy Bradley earlier this month.

On the other hand, Cotto has decided to delay his comeback fight. The Puerto Rican was supposed to fight in June, but has already informed promoters that he will not return two months from now. Cotto is reportedly eyeing a showdown with Mexican boxing warrior Juan Manuel Marquez.

Marquez, who has not fought since his unanimous decision win over Mike Alvarez in May 2014, is also on Mosley's radar after his showdown with Avanesyan.

"I also want a fight with Juan Manuel Marquez," Mosley said. "After my fight on May 28th we can get it on."

Mosley recently told reporters that he is not planning to retire soon, which was the main reason why he decided to train under legendary boxer Roberto Duran.
