It is always great to see to great fighters square off in a cage, but true MMA fans also love to see these fighters spar. After all, it is the training, day in and day out that help these guys get to the level they are at. Good training and sparing partners can help a fighter get the best out of their practice sessions. The best train with the best. Here is a cool clip that shows Wanderlei Silva sparing with Antonio Nogueria. Props to The GARV for finding this.
