The 37 year-old, who held the IBF super-featherweight title from 2000 to 2002, was asked to do some rounds with the former pound for pound king and joined another ex-world title holder in Kendall Holt, amongst others.
Having worked with Pacquiao as he prepares to face dangerous American Timothy Bradley once again on April 12 in Las Vegas, Forbes told WBN that the ‘Pacman’ is almost hitting peak form with the fight just under two weeks away.
“I have been feeling pretty good in there with him myself, but I would say Pacquiao is about a 9 out of 10 at the moment,” Forbes told World Boxing News.
“Being that he was a little sick last week he was still putting the rounds in like a pro. It was nothing hurtful in there as I don’t know what hurtful is, but I know I have definitely been helpful to him as he gets to work for Bradley.
“Pacquiao is a season boxing competitor at championship level and has plenty of experience at the very top.”
When asked about Pacquiao’s chances of redemption against current WBO champion Bradley, Forbes explained that he was already with the majority who say Pacquiao took the first meeting and there is nothing to suggest he can’t repeat that feat next week.
“I thought Pacquiao had won the first fight, but I was also happy that Bradley was in a big fight, which was well deserved,” said Forbes.
“Looking at the first fight, I do believe Pacquiao can take the second because of the way he did it the first time around and I think it should be a good fight.”
Talk of a super-fight between Pacquiao and world number one Floyd Mayweather seems to have calmed down of late as the winner of Amir Khan v Luis Collazo is already lined to face ‘Money’ this September.
Mayweather, 37, tackles Marcos Maidana first off on May 3 at the MGM Grand, and with just two space left for the huge welterweight match to be made in 2015, Forbes says it’s not looking a likely scenario.
“It’s probably been too long in the making for Pacquiao and Mayweather, which makes me doubtful now that it will happen.”
