Its something Ive never seen live, something Ive never experienced before. Its exciting.

I scored and it was an all round great day. If we could experience those sort of emotions again, this weekend it would be great.Its useful that you have experienced these kind of big games before, those pressurised games. This one will be slightly different but again the stadium will be full.
