Hall of Fame Referee, Joe Cortez does not believe Manny Pacquiao will defeat Floyd MayweatherReuters

Though the fight of the century between Floyd Mayweather Jr-Manny Pacquiao might not have been finalised, people associated with the sport have already started to give their predictions for the match.

The match, which has been tentatively scheduled for 2 May 2015, Hall of Fame referee Joe Cortez feels Mayweather will defeat Pacquiao in the mega event.

"Manny Pacquiao looked outstanding in beating Chris Aleigri, but don't forget Aleigri is not the same level as Mayweather," said Joe Cortez, as quoted by BoxingScene.com.

Manny Pacquiao's easily defeated Chris Algieri during a bout in November 2014. Many believe that the American was below par when he fought Pacquiao.

But one has to give credit to Pacquiao, who looked a confident pugilist landing the right blows.

"Mayweather is a superior fighter with many years of experience and has held on to that championship for over 17 years, that tells you something about his calibre of a fighter."

Mayweather was also named the fighter of the year in 1998 and 2007.

Though the 37-year-old boxer might be rich in experience, he is no longer the same as he was a decade ago.

''Chris Aleigri was on another level – I thought he was gonna perform better, but he did not and Pacquiao looked outstanding putting him down on six occasions. ''

"I'd still have to go with Mayweather for this fight because he's undefeated and he's been there for over seventeen years as a world champions, but in boxing, things can go wrong for you over night. In boxing, they say you can get over old night."

The American has a tremendous record, where he is unbeaten in 47 bouts, which includes an impressive 26 knock-outs as well.

"Mayweather knows his body, he knows how to take care of himself and that is why he looks so young when he's fighting, he looks like a twenty year old, he maintains himself in good shape at all time."

If the Mayweather-Pacquiao clash takes place, which is not confirmed yet, would be the highest grossing fight in history. Meanwhile, Pacquiao has agreed to all the demands that have been put forward by Mayweather's camp for the bout.
