Hall of Fame trainer Freddie Roach would like to see Manny Pacquiao retire from the sport.

But if the 38-year-old veteran continues to fight, then the only fight Roach would like the boxer to even consider is a rematch with Jeff Horn.

Last weekend, before a crowd of over 51,000 at the Suncorp Stadium in Brisbane, Horn secured a twelve round unanimous decision over Pacquiao in a shocking upset to capture the WBO welterweight championship.

There is a rematch clause in the contract, so Pacquiao has the option of an immediate rematch if he so chooses.

Roach would like Pacquiao to at most, have the rematch with, and then retire, but he's unsure if that's going to go happen because Pacquiao may not want to retire off a victory.

The biggest issue, according to Roach, is the Pacquiao doubling between being a boxer and being a full-time politician.

“Being a congressman, it seemed like Manny really wasn’t pressed or challenged by it,” Roach said to USA Today. “But being a senator, he’s like a whole different person. It takes a lot of his time, and the thing is, the first half of training camp wasn’t the best because he was being a senator, and sometimes they’d let him out at three o’clock and sometimes they let him out at nine o’clock. Sometimes 10 o’clock. And then we have to train after he gets off work. Being a great fighter and being a great person in politics, it’s just very, very difficult to do both, I feel.”

“I told Manny, give it a week, we’ll sit down and talk and see what’s next. I said either we retire or fight a rematch at this point. Which decision? We should take some time and watch the fight on tape, and then I’ll have a long talk with Manny about what’s the best place to go: To fight (Horn) in a rematch, or possibly retire, or go on to bigger and better guys. Those are his options.”

“I think what’s on his mind is what we talked about, having two jobs and you can’t really do both. I hope that sunk in to him so he thinks about it. But right now, more realistically, is either a rematch with (Horn) or nothing. That’s it. That’s pretty much my thoughts, and I don’t think we ought to go after any other world champions right now. I would like a rematch and then if he wins that, it’s over. But is that possible? Can you retire off a win?”
