Arsene said: "It was not a corner, never, but what can you do about decisions like that? It didn't help us, but in the end we had the chance to defend the corner but we didn't. And then we didn't defend the cross for Heskey to score.
"It has made it difficult for Liverpool to contest the title. It is between ourselves, Manchester United and Newcastle are now in it. I was happy with the way we played, the style. Ask the fans what they felt, it was a great game.
"We did 90% of the job but didn't finish the way we should have. But a point here is still good, it was frustrating for us but not too bad with a draw in the end."
