In his last bout in Macau??in November Pacquiao, an eight-division world champion, defeated Chris Algieri via a unanimous decision to retain his WBO welterweight crown.
After calling out Mayweather in the aftermath and the long-awaited clash between the two finally looking likely, Pacquiao and the undefeated American have been trading blows on social media ever since.
Pacquiao said on Monday: “Floyd brags about his lifestyle and everything! I don’t care. I’m just waiting here for him to sign the contract.”
Mayweather had touted May 2 as a possible date for the fight to take place but also insisted that the bout will only happen on his terms.
The pair had been due to meet in March 2010 before negotiations over drug-testing broke down.
