WWE World Heavyweight Champion Brock Lesnar opened up Wednesday about his upcoming match against John Cena at Night of Champions on Sunday live from the Bridgestone Arena in Nashville.

Speculation On John Cena Winning WWE Championship Sunday

Lesnar sat down with WWE announcer Michael Cole and discussed his dominance over Cena at SummerSlam on Aug. 17 at the Staples Center in Los Angeles and The Undertaker at WrestleMania.

"I think we can go back further than [SummerSlam] to my victory over The Undertaker [at WrestleMania XXX]," Lesnar said. "It's plain and simple for this and I can keep saying this and it's like a broken record all the time, but I came back to this company for one reason and one reason only and that was to be at the top...To be the WWE World Heavyweight Champion. Everything that's been put in front of me I think I've accomplished."

Cole then asked Lesnar if his mindset is different now that he is the one being hunted as champion.

"I don't come into any fight with any other mind set than to just kick a--," Lesnar said. "That's all my job is. That's plain and simple; I've got the best job in the world. Eat, sleep, kick a-- repeat. That's what I do. And I happen to enjoy it and I happen to be very good at it. I'm not here to play off of anybody else's emotions. I'm not here to play off of what other people think. Brock Lesnar is the face of this company, I don't know when people are actually going to get that through their head."

Lesnar addressed the fact that Cena has been trying to prove he can beat "The Beast," but the WWE Champion said he doesn't talk and he has Paul Heyman to do his speaking for him.

"I'm not a man of many words all right? That's why I have a guy that does all my talking for me," he said. "Now John Cena on the other hand can talk all he wants to about what he's gonna do. Kudos to John...He's been at the company for a long time. He's talked the talk and he's walked the walk, but he's finally faced a man that neither of them works. I don't care what kind of John Cena shows up on Sunday, I really don't. It's not gonna change my game plan at all. Not one bit."

Lastly, Lesnar promised that Cena would go down again on Sunday night.

"I am a prize fighter," Lesnar said. "I come to Monday Night RAW to promote fights. That's my job. I showed up on Monday night to promote Night of Champions and it just so happens that John Cena is all fired up about this match on Sunday. And so am I, it's plain and simple. On Sunday, John Cena is going to get another a-- beating."
