Pacquiao says age no barrier to success

Philippine boxing legend Manny Pacquiao insisted today that his advancing years were no barrier to success as he gears up for a showdown against world champion Lucas Matthysse.

Pacquiao, 39, will fight the Argentine -- four years his junior -- for the World Boxing Association welterweight belt on July 15 in Malaysia's capital Kuala Lumpur.

The Filipino has won an unprecedented eight world titles in different weight classes but some have raised questions about his ability to box at the top of his game due to his age. But at a joint press conference with Matthysse in Kuala Lumpur, he dismissed such concerns.

"It's not about a number, it's not about age, that doesn't matter," he said.

"It depends how you discipline yourself in training, how you prepare." Pacquiao said that the fight against Matthysse would not be his last, as he wants the final bout of his career to take place in his homeland.

"Definitely this is not my last fight," he said. "I think I still have got a couple of more fights (until I) retire."
