UFC 91 - Brock Lesnar highlights
Watch Lesnar charging opponents like an angry rhino and talking about facing Couture on 15th November
Lesnar is a fighter with a lot to prove. His former career as a WWE wrestler has lots of people believing he hasn't got what it takes to handle the real tough nuts of the UFC.
So far his two UFC fights have only partially proved them wrong – while he smashed Heath Herring, he was submitted by an over-the-hill Frank Mir. Fighting the legendary Couture will give him a chance to silence his doubters.
