To quote Kevin Keegan: "I'd love it if we beat them.
Love it!"
But I must add, a draw must be considered a highly acceptable result. We are without Marchisio and San Paolo is a fortress. Not many teams pick up points there.
That said, the actual proceedings of the game might change my view. If we, for example, strike the post 2-3 times and get valid penalty claims ignored, Napoli scores with their only chance of the game etc. I will undoubtedly be very displeased with a draw.
