The UFC Heavyweight Champion's return to action is now fast approaching in his eagerly anticipated unification fight with Interim Champion Shane Carwin at UFC 116.
This is being billed as (and could very well be) one of the biggest fights ever inside the octagon, both physically and in PPV terms.
But for many people the Champion's return is just the resumption of Brock Lesnar's rise to the top as the greatest Heavyweight ever.
So, with that in mind, what does Brock Lesnar have to do to become the greatest Heavyweight of all time?
I know No.1 is to defeat Shane Carwin at UFC 116, but what are the rest?
