Mayweather and Pacquiao posted videos on social networks about encounter they had in a club. Looks like Mayweather ran into Pacquiao in a event and they start to call each other. Pacquiao said “.. i have the belt” and Floyd said “I’m going to take it from you like I did before”.
During the video Floyd was mentioned December couple times, and then in the end of the video he said:
I am coming back in December
