If the rugged Mexican overcomes WBO welterweight titleholder Timothy Bradley, there is likely even less of a chance that Manny Pacquiao will fight Juan Manuel Marquez for a fifth time.

Marquez (55-6-1, 40 KOs) is slated to battle the 29-year-old Bradley (30-0-0-1, 12 KOs) on October 12 at the Thomas & Mack Center.

Conversely, the 34-year-old Pacquiao (54-5-2, 38 KOs) will face Brandon Rios on November 23 at the CotaiArena in Macau, China.

During their fourth savage affair in December, Marquez brutally knocked Pacquiao onto Queer Street at 2:59 of the sixth round.

With the Filipino controversially earning a draw and two conquests over the ballooned Mexican in their previous bouts, Marquez was allegedly offered $13 million to again throw fists with Pacquiao.

"If Marquez wins (against Bradley), he will ask for even more money from us," said Pacquiao adviser Mike Koncz.

No matter the outcome of the match against Bradley, Marquez claims to be done with the “Fighter of the Decade” for the 2000s by the BWAA.

"Keeping that feeling would be grandiose, and to have my Mexican supporters and the whole world enjoy that feeling and say, 'Remember the best pound-for-pound fighter that was knocked out by Juan Manuel Marquez?' — to me, that is worth more than all the money in the world," Marquez, who turns 40 in August, told ESPN Deportes over the weekend.

"I don't think about that (fifth fight) anymore. We know that the offer will be tempting, but it isn't worth more than the feeling, what was lived, what was acquired after that knockout. That's worth more than several million dollars. I would rather retire with this feeling than take a risk in whatever happens with Pacquiao."

Questions “about that (fifth fight)” are irrelevant because, in an extremely competitive slugfest, Bradley should outscore Marquez to remain an undefeated titlist this autumn.

In stark contrast to Marquez, Pacquiao will manage to finish the inferior 27-year-old Rios (31-1-1, 23 KOs) within 11 rounds.

Ultimately, Juan Manuel Marquez will “retire with this feeling.”
