Manny Pacquiao could still land a long-anticipated bout with Floyd Mayweather so long as "both sides cut out the crap", believes the Filipino's promoter Bob Arum.

The 34-year-old was an emphatic winner at the weekend as he got his career back on track with a unanimous decision against Brandon Rios at the Venetian Casino in Macau.

Pacquiao looked back to his best following a contentious loss to Timothy Bradley on points last year and a brutal knockout at the hands of Juan Manuel Marquez.

There has been a suggestion that Pacquiao could face Marquez for a fifth time in April 2014, while a rematch with Bradley is another possibility after the American secured a hugely impressive win over the aforementioned Mexican in his last bout.

Teak tough Russian Ruslan Provodnikov has been mooted as another potential opponent but fans are calling out for Pacquiao to finally share a ring with Mayweather, in order to finally prove just who is the better fighter.

After defeating Rios it was Pacquiao who called out the brash American, saying: "I am willing to fight Floyd, so it's up to him."

And it seems Arum truly believes that there is a possibility that the fight could be made.

"I know it's a fight that should happen and where there is a will there is a way," Arum told ESPN. "If all sides cut out the crap, it can be done."

Mayweather has two fights into a six fight deal with American television network Showtime and is currently seeking a new opponent after dispatching Saul Alvarez in September of this year.

A fight with Pacquiao has come close to being signed on several occasions in recent years but there have been demands from both fighters which have led to a bout never being signed and sealed.

However, there are few fighters out there that could deliver such a substantial audience and should Mayweather decide that he wants to face 'Pacman' then he would be assured of one of the biggest purses in boxing history.

There may well be some problems to overcome though as Pacquiao works with rival US cable company HBO, while the purse split and drug testing will also be vital as these factors have previously scuppered any possibility of a fight.
