Luke Rockhold minced no words when giving a prediction for his UFC 199 main event rematch with Michael Bisping. The UFC middleweight champ is notoriously confident, but for this one, he said there’s no doubt.

“I know that I’m going to knock Michael Bisping out in devastating fashion,” Rockhold told MMAjunkie. “I don’t think it, I know it. I know it’s going to happen. I’m going to stay composed, I’m going to find my timing, I’m going to pick my shots and then I’m going to lay the smack down.”

UFC 199 takes place June 4 at The Forum in Inglewood, Calif. Rockhold (15-2 MMA, 5-1 UFC) vs. Bisping (28-7 MMA, 18-7 UFC) headlines the pay-per-view main card following prelims on FOX Sports 1 and UFC Fight Pass.

Rockhold, No. 1 in the latest USA TODAY Sports/MMAjunkie MMA middleweight rankings, has already handily dispatched of No. 6-ranked Bisping once before. He stopped “The Count” by second-round submission at UFC Fight Night 55 in November 2014.

Under normal circumstances, a rematch wouldn’t have come together so soon. But when Rockhold’s original UFC 199 opponent, Chris Weidman, fell off the card due to injury, Bisping and his three consecutive wins since losing to Rockhold were deemed the most appropriate replacement.

Rockhold dropped Bisping with a head kick before finishing him with a one-armed guillotine choke at UFC Fight Night 55 in showing that earned him a $50,000 “Performance of the Night” bonus. It’s hard to win more impressively than Rockhold did in the first fight, but he promises to upstage his previous effort.

“It’s going to be hard to top, but I guarantee I’m going to top the last performance,” Rockhold said. “It’s going to be that much more precise, that much more devastating. I feel great about this fight. I felt the same about (original opponent) Chris Weidman and it doesn’t matter who I’m going to be in there with, I just know my level has changed from any of these guys and no one’s catching me anytime soon.”

Rockhold, 31, said Bisping, 37, is going to have a difficult time thwarting what he brings to the table. The 185-pound champion, who is out to make his first title defense at UFC 199, owns a five-fight UFC stoppage streak, the longest active streak in the company. That includes wins over the likes of Weidman, Lyoto Machida, and of course Bisping.

The American Kickboxing Academy product has been close to unstoppable since suffering a highlight-reel knockout loss to Vitor Belfort in his octagon debut at UFC on FX 8 in May 2013. However, the setting of a rematch is a first in Rockhold’s career and while that could hinder some fighters, he said it would make him thrive.

“I already have an understanding of what he can bring to the table,” Rockhold said. “If you’re smart you study up and you have an understanding of what you’re in for going into these fights. But there are always a couple variables where you don’t know exactly how you’re going to feel. I know what Bisping does through and through. I haven’t seen too much change. I don’t think he’s declined, but I haven’t seen much get better, and he’s about to find out that I’ve taken my game to another dimension.”

Although Rockhold and Bisping share mostly negative feelings toward one another, as displayed on UFC 199’s pre-fight media conference call, the champion said he appreciates his challenger. Just not for the reason one might think.

“Bisping can definitely sell a fight,” Rockhold said. “(Ronaldo) ‘Jacare’ (Souza) can’t speak English, he can’t even pronounce his name right. Weidman, I don’t know what the hell he’s doing. Going into the last fight, I don’t even know if he believes in himself. It’s refreshing to have some guy at least talk like he believes in himself. These guys – they’re all in for something special.”
