As the UFC’s reigning welterweight champion, Montreal’s Georges St-Pierre has everything a professional fighter could dream of. He’s only 31, but has long been considered an all-time UFC great, and is one victory away from overtaking the division record of seven successful title defences he currently shares with Hall of Famer Matt Hughes.

The "King of Pay-Per-View," as UFC president Dana White has referred to St-Pierre, is one of the most popular and wealthy MMA athletes ever.

But suggest that he’s become "pampered" and has people "powdering his nose," like his UFC 158 opponent Nick Diaz did recently during a media session with St-Pierre, and the normally reserved champion shows a rare glimpse of his temper.

"Let me tell you something, uneducated fool, listen to me … I've not always been like this," St-Pierre shot back at the Stockton, Calif.-based fighter. "I've not always been rich. I started from the bottom. I made myself, I worked very hard to be where I am now."

The cutting remarks were the latest in the war of words between St-Pierrre and the mercurial Diaz, a feud that will finally be settled in the cage Saturday night at Montreal’s Bell Centre.

The fighters’ approaches to combat couldn’t be more different. In St-Pierre, you have what many consider to be the most efficient machines in the mixed martial arts game — an explosive athlete with excellent striking, unparalleled wrestling, and a sharp mind for strategy. Diaz, on the other hand, is a relentless, Terminator-style slugger — he stalks his prey, never shies away from contact, and looks to chisel away at his challengers with vicious boxing.
