Anderson Silva likes a challenge. Right now, his only challenge may be Georges St. Pierre.

The pound-for-pound king and reigning middleweight champion spoke to Mike Straka on his show “Fighting Words with Mike Straka” and had this to say about a potential superfight with GSP (courtesy of MMAJunkie.com):

“Georges St-Pierre is one of the best,” Silva said through an interpreter. “He’s shown that he’s a great athlete, and I really train hard everyday to fight the best. I do believe it’s a superfight, and it’s a fight that must happen someday.”

Both men still have one test in front of them for this fight to happen as GSP must get past Jake Shields next Saturday and Silva will now face Yushin Okami at UFC 134 in late August.

Both champions seem to be heavy favorites to win their fights but both of their opponents have the skills to pull off the upset.

Shields has the best submission grappling that St. Pierre has ever faced and Okami has the strength and wrestling background to get Silva to the ground.

If both champions win, it likely sets up the long-awaited GSP-Silva showdown around the end of 2011. It would be the biggest fight in UFC history and truly be the showcase of the top two fighters in all of MMA, in my opinion.
