(CNN) -- He may have knocked out eight-division world champion Manny Pacquiao during their recent bout in Las Vegas but if Juan Manuel Marquez wants a fifth fight against the legendary Filipino he'll need to get permission from his wife.

The Mexican stunned the world of boxing by knocking out Pacquiao in the sixth round of their welterweight contest earlier in December.

It was the first time the 39-year-old has claimed victory in four fights against Pacquiao, who many pundits regard to be the finest pound-for-pound fighter the sport has ever seen.

But with fans clamoring for a fifth bout, Marquez says the only way it will become a reality is if his wife allows him to renege on his promise to retire whatever the outcome of the fourth.

"I made a promise and I know that promises are debts," Marquez said in an interview with CNN en Espanol.

"I don't see a case to fight again but logically he wants a chance," he added of talk that he and Pacquiao could square off for a fifth time.

Marquez's emphatic victory offered the Mexican some redemption after he failed to win any of the first three fights against Pacquiao.

Their first encounter in May 2004 ended in a draw, while the Filipino took a points victory at the conclusion of their rematch four years later.

But their third clash in November 2011 ended in controversy when Pacquiao was awarded victory in a marginal points decision.

The crowd booed as the judges' verdict was read out and Marquez claimed he should have been declared the victor.
