Sonnen named the biggest fee in his career

“The biggest fee in my career is $8.8 million in one night. I took 8.8 million for the second fight with Anderson Silva. This was in 2012, and let me tell you, the numbers are higher than many believe. I've always wondered how much Anderson got. He should have gotten more,” Sonnen said in an interview with YouTube channel Flagrant.

Recall that Sonnen and Anderson Silva met twice in the octagon. In 2010, the Brazilian won by submission, and two years later - by technical knockout.
