Manny Pacquiao-Floyd Mayweather clash is expected to break all box office recordsReuters

Floyd Mayweather or Manny Pacquiao -- take your pick, as the two best pound-for-pound boxers fight it out at MGM Grand on Saturday night with huge pride at stake for both the boxers, apart from the huge money in the offing.

These two boxers were initially expected to fight about five years ago, but the fight did not materialise then. So after some tedious negotiations between Mayweather and Pacquiao's camp, they finally agreed for the 2 May 2015 fight.

Some experts believe that the fight could have been better if it was fought five years ago. Some may agree or disagree, but one should just be happy and excited as the eight-division world champion Pacquiao finally takes on five-division world champion Mayweather.

A classic fight is expected between the two of the greatest boxers of the modern era.

The bout, which has been touted as the fight of the century, has garnered interest from all around the world and everyone is eagerly waiting for the bout that is going to break all box office records that exists in boxing history.

The fight might purse more than the expected $300million.

With less than 24 hours for the fight, former and current boxers, other sportspersons, musicians and actors have already made their predictions for the mega fight.

Bookmakers have already tagged Mayweather as favourite to win the bout, but the American knows the herculean task that is set ahead of him. Though Pacquiao may have an inferior boxing record when compared to Mayweather, who has not lost a single bout in his professional career, the Filipino has it in him to throttle the American's unbeaten streak.
