The rivalry between UFC welterweights Nick Diaz and Georges St-Pierre appears to still have life after a period of relative silence between the two. Diaz has been lobbying for a shot at St-Pierre since joining the UFC’s roster last year, irking GSP so much with his disrespectful antics the typically reserved champion made it a point to ask UFC President Dana White to make the match. However, St-Pierre suffered a serious knee injury, leaving Diaz to fight Carlos Condit who ultimately outpointed him and earned a shot at the French-Canadian’s belt last night as a result.

As might be expected, Diaz made sure to tune in to watch the tilt and didn’t waste any time before commenting on what he witnessed.

“I am not impressed by your performance,” cracked Diaz to St-Pierre on Twitter, echoing an infamous line delivered by “Rush” to Matt Hughes in 2006 after beating B.J. Penn.

St-Pierre caught wind of Diaz’s remark and addressed it during the UFC 154 post-event press conference, pointing to the fact he beat Condit whereas Diaz didn’t.

The remaining heat between St-Pierre and Diaz could be a factor in GSP’s decision to accept a super-fight with middleweight king Anderson Silva or stay at 170 pounds and continue defending the belt he’s worn for seven straight scraps.
