1. Chuck Liddell vs. Wanderlei Silva

UFC 79

Both of these fighters came into this match after long careers and with heavy chips on their shoulders, and it was clear once they got down to business that there was no love lost between the two. After a slow feeling out process, this turned into one of those bloody, brutal affairs between two of the best known fighters in the entire sport. Liddell won by decision, proving the "Iceman" still had the goods.
