Philippines boxer-turned-politician Pacquiao, 42, returns to the ring against WBC and IBF welterweight title holder Spence Jr on August 21.
Pacquiao's boxing comeback has been met with an excellent deal of scepticism, chief among them Mikey Garcia, who has questioned whether the Filipino senator still possesses the stamina to stay up with "the youth, the dimensions and skills" of Spence Jr.
But Tyson has refused to write down him off completely. In fact, 'The Baddest Man on the Planet' actually rates Pacquiao very highly and fancies his chances against 'The Truth'.
Asked if the legendary Pacquiao could beat Spence once they clash next month, he replied via ESNews: "It’s getting to be an honest fight.
"You can't rule out Pacquiao because he beat Thurman. i feel Pacquiao, he beat Keith Thurman.
"Pac can move and s—, which can mess you up, that is what f—s everybody up, he's everywhere the place."
Tyson (50-6, 2 NC, 44 KOs), 55, of latest York, USA, is taken into account one among the best heavyweight boxers of all time. The 55-year-old became the youngest heavyweight champion in history when he knocked out Trevor Berbick at the Las Vegas Hilton in November 1986. However, after he lost three of his last four fights, including upset losses to Danny Williams and Kevin McBride, he retired in June 2005.
The former undisputed world heavyweight champion also revealed that he's curious about exhibition bouts against Evander Holyfield and Lennox Lewis following the recent success of his celebrity match with Roy Jones Jr.
