Floyd Mayweather has decided to keep the war of words going with career rival Manny Pacquiao.

The two superstars began trading words on social media on Tuesday - and for the moment there appears to be no end in sight.

After Saturday's fight, Pacquiao called for a rematch with Mayweather - who won a twelve round unanimous decision in their 2015 mega-bout.

Pacquiao has long claimed that a shoulder injury hindered his performance in their showodwn - and he's confident of victory in a rematch.

During their recent online exchange, Pacquiao baited Mayweather to accept a rematch - and Mayweather once again erupted.

"Let's stick to the facts! Bob Arum is no longer your promoter, so when it comes to Mayweather Promotions & PBC events I’m the HNIC! Bottom line, I make more money than you; I beat you, then I signed you! I was only at your fight supervising you, my employee, as any real BOSS would do," Mayweather stated.

"You made $10 million for 12 rounds, when I just made $9 million in under 3 minutes playing around in an exhibition with a pizza delivery guy! I beat you mentally, physically and financially! Remember, you fight cause you have to, I fight when I want to!"
