WBO welterweight champion Manny Pacquiao has continued to challenge WBC/WBA champion Floyd Mayweather Jr. on the social networks. Earlier today, Amir Khan posted a photo to the social networks, letting Mayweather know that he wants to beat him in 2015.

Now Pacquiao has posted a photo of his own, advising Mayweather that he's waiting on him to sign a bout agreement. There are ongoing negotiations for a Mayweather-Pacquiao fight. Promoters have failed for several years to put it together, but now both fighters are calling for the match.

"Floyd brags about his lifestyle and everything! I don't care! I'm just waiting here for him to sign the contract! #fightpacquiao," Pacquiao wrote.
