Manny Pacquiao has confirmed there is 'a big possibility' he will fight old adversary Floyd Mayweather again in a bid to finally settle the pair’s old rivalry.

Billed as the ‘Fight of the Century’, the first contest between the two took place in 2015 at the MGM Grand Garden Arena, Las Vegas, with Mayweather winning by unanimous decision.

Although one of the most anticipated fights in boxing history, Pacquiao’s defeat was widely considered a flop by both fans and critics alike.

The two fighters have already hinted at a rematch, with Mayweather suggesting before the end of the year, and the even hungrier Pacquiao wanting it finalised by September.

However, both now have other challenges with Pacquiao fighting Adrien Broner in January, and Mayweather fighting Japanese kickboxer Tenshin Nasukawa on New Year’s Eve.

But Pacquiao has made clear that discussions will then be held for a rematch in which the two can deal with what remains of their unfinished business.

Speaking at the Oxford Union, Pacquiao claimed: “There’s a big possibility because Floyd is coming back into boxing." per Sky Sports. "He is fighting in December and I am fighting in January. So a big possibility after that next year, that we will discuss a re-match.

"My thinking is to have a re-match and to make a clear decision on who will win the fight because in the last fight that we had it wasn’t clear who won the fight because he didn’t throw a lot of punches and he won the fight.

"I had a shoulder injury… but this time, if this rematch happens, there are no excuses, no alibis.”

The fight has been talked up in the wake of Mayweather’s signing to RIZIN Fighting Federation, a mixed martial arts company, and his upcoming fight with Nasukawa.

The former five-weight world champion has already beaten UFC’s Conor McGregor in a boxing match in August 2017, extending his unbeaten record to 50 wins, before more recently considering potential bouts with UFC’s Khabib Nurmagomedov, and, Pacquiao.

Mayweather has not fought since the McGregor bout and on Nasukawa has said: “I wanted to do something different. I wanted to display my skills outside the US and be in a special fight. I want to give people what they want – blood, sweat and tears.”

Perhaps this will be the ‘Fight of the Century’.
