"I can't really complain about the penalty. He got there just before me and the way players do, he went over me. There was a bit of contact. It was more a case of he ran into me more than I went into him but the referee gave it and that's the way it goes sometimes."

"I thought Neil Sullivan was a bit slow coming off his line and I think he just misread the pass from Jobi McAnuff. I saw the 'keeper coming out and he didn't stop as I was about to knock the ball around him - he took me out."
