He said:
"I've been confident all season and now we're in a good position with a good points total and we want to do it again. There's still a long way to go - nine games, including some difficult games - so we wanted to extend our lead today and we did that.
"We feel it's down to Highbury as we still have four games at home, including Manchester United. We went into today's game with the sense that Highbury will be important, but I wouldn't rule Newcastle out as our main opponents because don't forget Manchester United have to go there."
He also commented on Thierry Henry's yellow card:
"Thierry felt a sense of injustice because he thought he had been fouled. The referee gave him a yellow card which was just enough. Then he had a few minutes on a high afterwards and I was scared he would react after the second free-kick.
"I didn't really consider taking him off - it was just that I didn't want him to get another yellow card. I told him to calm down during the game."
