Broner will defend his WBC lightweight title in Atlantic City with Welshman Rees being a massive underdog to bring the belt back to the UK.
The brash American has compiled an impressive 25-0 record, with 21 of those wins coming inside the distance.
He has been touted as the next Floyd Mayweather but Rees, who briefly held a world title at light-welterweight five years ago, thinks he has the tools to expose some chinks in the armour.
"He's got all the mouth let's see if he can back it up," said Rees. "It's just a normal fight to me to be honest, it's just a ring.
"I've been over to Paris and won so fighting away from home doesn't bother me in the slightest.
"He's pretty cocky and I think he underestimates me. The game plan we've got is right and I'm confident in my own ability, he expects me to just come running in head first but he'll have a shock on the night, a lot of people will.
"His attitude stinks man. He shows fighters no respect, but he hasn't even earned the right to do that. What has he done? I've been in the States for five weeks now and American boxing fans don't like him.
"They tell me they hope I beat him and shut him up. I think he acts like a fool for no reason and no one really likes that.
"Who has he fought? I've seen his fights and half of those guys just stood in front of him letting him dictate the pace of the fight. I'm not going to let him do that. This is the first fight that I have trained away from home because I'm going to show him I'm no walk in the park.
"I've never been stopped. I can take him out in the first round, but I am ready to go into deep water if I have to. Ether way, I have trained hard and will be ready to dictate the pace of the fight and not let him get away with a lot of what other fighters have let him do.
"I have to watch for his right uppercut which he throws from down low, but he's not the best on his feet either. Work rate is going to be important."
Broner, 23, insists he respects Rees as a fighter but insists the Welshman will be a stepping stone to his goal of being recognised as the best in the world.
"I don't underestimate him [Rees]. If we stood face-to-face, I probably couldn't see him, but I respect him as a fighter.
"I respect every fighter because only a boxer knows what we go through once we get into that ring.
"He [Rees] is a former champion at light welterweight. He's coming down in weight so he is used to getting hit by strong fighters.
"I am not about to miss the boulder on this man's shoulders. He is going to be there all night or until I put him to sleep.
"We are going to be eating ice cream in no time.
"This is going to be a fun year for me. I'm not looking past this fight, but I'm ready to fight whoever. We're going to take care of business Saturday night.
"To this day, right now, I could literally leave boxing and be like, 'I did more than anybody in my family ever did.' I could provide for my kids and my family, but I'm not going to settle for that. I'm trying to be the best boxer to ever lace up a pair of gloves. That's my goal."
