Timothy Bradley has vowed to put in a special performance when he meets Manny Pacquiao in las Vegas on Saturday night.
The undefeated American is expected to provide a stern test for Pacquiao after a string of impressive performances that has seen him earn a reputation as one of the most feared men in the light-welterweight division.
Bradley dominated the 140lb division before deciding to move up in weight in order to challenge Pacquaio for the WBO welterweight title.
The 28-year-old may not be the most flashy performer and his record of just 12 stoppages in his 28 professional fights means that he often outclasses his opponent over the full 12 rounds.
"I don't look pretty, I don't look spectacular, I don't have that spark," said Bradley. "I don't do that one thing where everyone says 'wow'.
"I know I'm going to have to do it in this fight. You could see some greatness on Saturday. It's all or nothing. No rounds off. Round by round, I have to win each one."
It will be some performance from Bradley should he manage to upset Pacquiao who has not lost in seven years, despite moving through the weight classes.
In fact the fighter from California has already highlighted the need to make an early impression and he hopes his natural power will knock Pacquiao from his stride.
"He's going to respect me, believe it. As soon as I tag him he's going to respect me," added Bradley. "I've got to stay behind a good jab and I've got to counterpunch the hell out of this guy. I'm going to put it all on the line."
