Former pound-for-pound king Manny Pacquiao has claimed that he has two or three years left in boxing.

The Filipino, who was ranked at the top of the sport a few years ago, has suffered consecutive defeats in his last two fights.

Many have called for him to retire, but the 34-year-old is keen to get back to his previous form ahead of a fight with Brandon Rios in November.

"It's a great opportunity for me to give a good show to the people," Pacquiao told reporters. "To get back my name into the top of boxing.

"I'm not really sure [how many fights left]. As long as I can still fight, I can fight. In my mind now, maybe I can still fight two or three years from now.

"I tell you frankly, honestly in myself I can still fight and I feel strong. If there is something wrong in my body or something wrong in my boxing skill I have to think about [retirement]. But since I lost the last fight, I still feel strong and I can still fight."

Pacquiao takes on Rios in Macau on November 24.
