Floyd Mayweather Jr. took the boxing world by storm after announcing his reemergence from retirement to fight again next year. And while details of the undefeated boxer’s return to action are not clear yet, multiple sources have already sent signals as to who the 42-year-old will square off against, including the highly-clamored rematch with Manny Pacquiao.

According to TMZ Sports, Mayweather Jr. might finally give in to the Filipino legend’s urge for a rematch after the former is said to be eyeing two fights in 2020, which also include a possible cross over to the UFC.

“Nothing is set in stone yet. It’s all being worked out and the situation is very fluid. But, for now, we're being told one name that's being seriously considered is Manny Pacquiao,” the report by TMZ Sports said. 

The 40-year-old Manny Pacquiao has been more vocal about his intentions to share the ring again with the American superstar and finish off the “unfinished business”. The fighting senator lost to a unanimous decision against Mayweather in May 2015 in what was tagged as the most expensive fight in professional boxing history.

Floyd Mayweather Jr., also a successful fight promoter, had been known to give vague responses whenever asked of the Pacquiao faceoff version two. But reporters believe his comeback next year will be the most ideal set up to redeem the letdown of an overhyped match four years ago.

“Floyd has been interested in a rematch for years and he feels the time is right -- especially with Manny being healthy and coming off a great victory over Keith Thurman,” TMZ sports added. “It's also worth noting that Manny is no longer repped by Bob Arum and is now a part of  Al Haymon 's promotion. Hayman famously works closely with Mayweather.”

A lot of fight fans are intrigued by the possibility of Floyd Mayweather Jr. stepping inside the Octagon. But experts believe that the MMA cross over is less likely to come about than the Pacquiao rematch.

“Don’t get too excited about the possibility of Floyd stepping into the Octagon, though. The 50-0 pugilist is infamous for never taking a fight he couldn’t win, and an MMA fight in the UFC definitely qualifies,” website MMA Mania exclaimed.
