Former world champion Robert "The Ghost" Guerrero could not make a prediction as to who will win the May 2 showdown between Manny Pacquiao and Floyd Mayweather Jr., saying the fight is a toss-up.
"It could go either way, with how fast Manny is," said Guerrero, as quoted by Boxing Scene.
"It all comes down to timing. If his timing is on, he can catch Mayweather," he added.
Guerrero is familiar with both men: he lost to Mayweather in 2013 and sparred with Pacquiao in 2005.
Mayweather is the favorite by oddsmakers, but Guerrero believes Pacquiao cannot be discounted.
"He does different things. You don't have a rhythm, and he's just so fast, in and out," Guerrero said of the Filipino star. "And his reaction time, my God, and those hooks."
"But anything can happen," he quickly added. "And everyone knows in boxing, one punch changes everything."
As for who he picks to win, Guerrero only said: "I think it's a pick 'em fight."
Pacquiao and Mayweather will face off on May 2 at the MGM Grand Garden Arena in Las Vegas.
