Georges St-Pierre has told Nick Diaz he is wasting his time with any trash talk, because he cannot understand what the granite-chinned brawler is saying.

St-Pierre will fight Diaz at UFC 143, with the UFC welterweight title on the line once again for the impenetrable champion.

Diaz got his shot after calling out St-Pierre at UFC 137, accusing GSP of faking injury in order to get out of a fight with Carlos Condit. St-Pierre, though, insists no words can bother him.

"I've seen it all from everyone before," St. Pierre said to QMI Agency. "If they're trying to get into my head and make me fight a bad fight, it's just mind games and it doesn't work.

"I don't even understand [or] speak English very well. I don't understand most of the things that [Diaz] says when he trash talks. I don't really care. I'm just going to focus on hurting him."

St-Pierre was also asked if he agreed that Dan Henderson's recent win over Mauricio Shogun Rua was the best fight in UFC history. GSP's answer was a simple 'no'.

"I didn't see the fight [live]; I saw it after," the Canadian said. "No, for me, it was not the greatest fight. It was a fight that displayed a lot of determination and heart, but I believe on the technical points, especially at the end of the fight, the guys were too tired to be able to make a display of technique.

"But it was an interesting fight for a lot of the fans because it showed a lot of heart and courage.

"Clay Guida's fight with Benson Henderson was pretty good. That was a good fight. It was a display of courage, determination and technique, as well. So they had everything in one. At the end of the fight, they were still able to deliver and the pace was high."
