Chael Sonnen spent the better part of four rounds beating up Anderson Silva.

In the fifth, “The Spider” caught Sonnen and scored a submission victory. A few years later, he defeated Sonnen a second time, ending their bitter rivalry.

Now, Silva is no longer the UFC middleweight champion, and Sonnen believes he has no chance at reclaiming that title when he faces Chris Weidman in December at UFC 168.

“He got knocked out cold,” said Sonnen, in a recent interview with MMAFighting.com. “Silva had two choices in that fight (vs. Weidman): he’d have fought serious and got beaten up, or he’d clown around and get beaten up.

“That’s not me speaking out against Anderson; he’s excellent. But, Anderson’s not Chris Weidman and he never’s going to be.”

The knockout loss was the first in Silva’s 38-fight career, and his first loss in the UFC.

“He’s just not Chris Weidman,” Sonnen continued. “He just stuck around too long and the next generation is here. There are guys who can beat him, but only a couple of guys.”
