Manny Pacquiao has insisted he will not hang up his gloves even if he loses his third straight fight against Brandon Rios later this month.
The 34-year-old expects to overpower the American in Macau as he looks to bounce back from defeats to Timothy Bradley and Juan Manuel Marquez.
Bradley ended Pacquiao's seven-year, 15-fight winning run with a controversial split decision victory in June 2012, and the Filipino great was then knocked out in the sixth round by Marquez six months later.
But Pacquiao declared he still has the desire to compete at the highest level, and he feels no added pressure to get his career back on track in his WBO welterweight title bout against Rios on November 23.
"It's one of the most important fights of my career because I want to show my fans and the world that I can still compete at a high level with elite boxers," Pacquiao said.
"I am expecting to win this fight. It's a really important fight for me in my boxing career because I lost the last two.
"It doesn't affect me. As far as boxing is concerned sometimes you win and sometimes you lose.
"I feel comfortable and confident about going on to win this fight, but I am not looking to retire if I lose this fight.
"My motivation is that boxing is in my blood. I enjoy it and I like to entertain my fans worldwide.
