Juan Manuel Marquez (53-5-1, 39KOs) admits he has a score to settle when he goes toe-to-toe with Manny Pacquiao (53-3-2, 38KOs) at the MGM Grand on Saturday night.
The 38-year-old Mexican veteran will be hoping it will be third time lucky against the Filipino pound-for-pound king after battling to a controversial draw in 2004, and losing a rematch by a single point four years later.
"That's why we are doing this third fight," said Marquez. "The first two were very close and this fight should end all doubt. We are not the only ones saying we won the fights, there are a lot of fans and media out there saying the same thing - that we won those two fights.
"If he is upset about what I said about winning the first two fights...well, I'm upset that I didn't get the decision.
"Without a doubt the fight is personal for me too," he admitted. "I didn't get the two decisions I thought I won.
"I think I will win this fight because I should have won the first two. It is going to be great because we both want this fight and we are going to give it our all.
"The winners are going to be the fans because we are two guys that are going to go in there and give it our all."
