Trainer Floyd Mayweather Sr. has advised Manny Pacquiao to avoid resigning with Top Rank, in order to make a mega-fight with WBC welterweight champion Floyd Mayweather Jr.

Mayweather returns on May 3rd at the MGM Grand in Las Vegas, likely against Amir Khan. Pacquiao is back, at the same venue, on April 12th against WBO welterweight champion Timothy Bradley.

Pacquiao's contract expires with Top Rank at the end of the year. Mayweather has stated in several interviews that he refuses to fight Pacquiao as long as he's promoted by Top Rank's CEO Bob Arum.

"Pacquiao, I think he should take that fight with my son and delete Bob Arum out of the situation and go for what he can go for, do the best he can do because right now he ain’t doing very good," Mayweather Sr. told On The Ropes Boxing Radio.

Mayweather Sr. clears up that he doesn't have any problems with Arum or Top Rank, but he wants to see Pacquiao break free so the fight can happen.

"Oscar De La Hoya left Bob Arum, my son left Bob Arum, these were the biggest fighters in the world at the time they left Bob Arum, and they are some of the biggest fighters still today. I think if Pacquiao had any sense, I think he would jump on the same wagon and get rolling. Don’t get me wrong, by no means necessary, I don’t have no problems with Bob Arum," Mayweather Sr. said. "Bob Arum has been good to me at times when my son was working with him, but it is what it is."
