Floyd Mayweather suggests Manny Pacquiao is 'slowly changing' for future 'Money' fight

"I didn't watch the fight, but from what I'm hearing, Marquez got cheated. Win, lose or draw, whoever I fight still has to be tested with random blood and urine tests ... I mean, the fight could've happened the way it happened because, you know, someone is slowly changing so they can prepare to fight me. They know they're going to have to take the random blood and the random urine tests ... I personally think it's Bob Arum having a vendetta. I think he's very very upset with me because, you know, I exposed and I opened the world's eyes up to different things. I never officially came out and said that I believe Manny Pacquiao is on steroids or that I believe he's on enhancement drugs; I never came out and said that he actually is. I only stated my opinion on what I believe in ... I just had an opinion. I didn't say, 'I know you doing this' or 'I know you doing that.' I said some jokes in the past, had fun, doing it smiling, and we talked about it, but if I was or wasn't joking, it's just my opinion. I'm entitled to my own opinion. People have said things about me, and wrote and criticized me about things in the past, but it goes in one ear and out the other. A lot of times, I don't hear about it because, like I said before, I don't read it if it's negative. If it's positive, then they know to bring it to me."
