Manny Pacquiao has predicted that he and Juan Manuel Marquez are going to clash in the best fight of the year on Saturday night.

The showdown will mark the third meeting between the Mexican and Filipino, after their first fight ended in a draw and the second in a contentious Pacquiao win in 2008.

However, the 32-year-old insists that this time is different.

"The difference of this training camp is I'm very motivated," he told reporters. "I want to do everything in training.

"There's going to be a lot of action, it's going to be a good fight. This is our last fight. I hope people will watch. It's going to be the fight of the year."

Pacquiao is expected to turn his attention to long-time rival Floyd Mayweather Jr. after the trilogy is concluded.
