O'Sullivan faces grudge match

Best of enemies Ronnie O'Sullivan and Mark Williams will meet tomorrow for a place in the Failte Irish Masters final.

"I can't think of anyone in the game who likes Williams, he just rubs you up the wrong way," O'Sullivan said in his autobiography, Ronnie.

Williams was not slow in delivering his response: "If you are stupid, you say stupid things. I always want to stick it up Ronnie every time we play."
