Glenn Rushton, the trainer of former WBO world champion Jeff Horn, says his boxer would love to do a rematch with eight division world champion Manny Pacquiao.

Last month at the MGM Grand in Las Vegas, the 40-year-old Pacquiao defied the critics by winning a tough twelve round decision over previously undefeated Keith Thurman to win the WBA welterweight title.

Two years back, Pacquiao lost a controversial twelve round decision to Horn in Brisbane. The victory gave Horn the WBO belt. Since then, the Filipino star has defeated Lucas Matthysse, Adrien Broner and now Thurman.

Rushton was impressed by Pacquiao's recent performance.

He believes Pacquiao was a better physical specimen than the boxer who lost a decision to Horn.

“I think he is, I think the fight galvanized him a bit,” Rushton said to Fighthype.com.

Before he can think about Pacquiao, Horn will first collide in the ring with Michael Zerafa in Bendigo on August 31.

Should Pacquiao want revenge, Horn and his handlers are ready and willing to make a second fight - but he warns that Pacquiao would suffer another loss.

“If ever Manny Pacquiao wants that fight with Jeff Horn, I think it’s unfinished business, then we’re up for it, we would certainly do it again,” Rushton said.

“I believe the outcome will be the same but I think it’ll be an even better fight than the first one.”

Before he tasted defeat for the first time, Thurman had actually praised Horn for his performance against Pacquiao.

“Go back and watch the fight (against Horn). That’s the day I gave him the nickname 'T-Rex Arms.' Jeff Horn was a real man. He manhandled Manny Pacquiao," Thurman said.
