Manny Pacquiao says he feels like a young man in his twenties and would relish another crack at Floyd Mayweather.

The Filipino icon, 37, ended a brief retirement to relieve Jessie Vargas of the WBO welterweight title earlier this month and said he was in great shape to avenge last year’s defeat to Mayweather in the richest fight in boxing history.

I feel young. I feel like I’m just 25, or that I’m just 28 years old, Pacquiao told ABS-CBN television.

Asked if he wanted to fight Mayweather again, Pacquiao said: Of course, if he wants to come back to boxing.

Pacquiao fuelled talk of Pacquiao-Mayweather II when he invited the undefeated American, who retired unbeaten in September 2015, to attend his successful comeback against Vargas in Las Vegas on 5 November.

Last week, Pacquiao teased fans about a possible rematch by posting pictures of himself on social media wearing a suit bearing photos of him and Mayweather in the garment’s lining.

But Mayweather, 39, said days later he had no plans to come out of retirement.

Pacquiao originally retired in May after beating American Timothy Bradley before standing for and winning a seat in the Philippines Senate.

But he said he would not be stepping away from the ring again any time soon.

I still believe in my skills. You just need discipline, how you discipline yourself and work hard, Pacquiao said, adding he would only walk away once he no longer wanted to put in the long hours of training.

Because once you get lazy, that’s the start of the decline of your performance and your body.
