Manny Pacquiao turns to Twitter to pile pressure on dilly-dallying Mayweather

HE may be installed as an early underdog against Floyd Mayweather Jr. but deep inside, Manny Pacquiao knows he has what it takes to inflict on the American fighter his first ever career loss.

“I can easily beat @FloydMayweather, I believe that,” Pacquiao said in a series of tweets in his account@MannyPacquiao.

Betting odds around the US already put the undefeated Mayweather (47-0, 26 KOs) a 3-1 favorite to win over Pacquiao since the 1996 Atlanta Olympic bronze medalist first announced he wants to fight the Filipino southpaw on May 2 following an interview with Showtime last month.

Of late, the 36-year-old boxing superstar has been putting the pressure on Mayweather, who remains uncommitted even after the camp of the Filipino fighter agreed to all the terms Floyd Jr. had earlier demanded, from the split in prize purse, fight venue, to the drug testing procedure.

Even the two rival cable network to which Pacquiao and Mayweather belongs --  HBO and Showtime – are already discussing ways of striking a possible joint pay-per-view telecast.

Still, Mayweather’s silence despite what seemed to be a major progress in talks of finally realizing a fight many believe will go down as the richest in boxing history has kept the bout still hanging in the air.

Other than his earlier pronouncement during the Showtime interview, nothing has been heard from the elusive boxer from Grand Rapid, Michigan.

Pacquiao though has been on the offensive ever since admitting he already agreed to the terms of the fight against Mayweather.

“If you really care about the fans, you will fight. If you care about yourself... you won't fight. #MannySmile,” said Pacquiao (57-5-2, 38 KOs).

The Filipino southpaw also said beating Mayweather will easily come down as the biggest upset of his fight career -- and of boxing in general, perhaps bigger than his ninth-round stoppage of the great Oscar De La Hoya.

“Everyone had me as a big underdog to @OscarDeLaHoya too. If @FloydMayweather fights me, boxing will get an even bigger upset victory,” said the Pacman.
