0 Kick-off: Newcastle get us under way for this mammoth clash.
I am in a state of shock as a 5-minute rendition by a Toon fan with "Top Chanter" on the back of his Newcastle shirt rings out moments before the game. I was wondering if the game would be delayed for a moment, but he has reached his final chord so the match is next.
My better half Fiona has written to my utter surprise.within seconds of wondering what she is going to say on tonight's game I read that she has a soft spot for Michael Owen. I'm sure the whole of Newcastle will if he scores this evening! Keep your views coming into me at firstname.lastname@example.org
Ralph who's a Notts County supporter emails in: "Really could be the (lesser-known) Magpies last chance. Shearer really gone for it with 3 unfit/out of form strikers upfront. No idea how it will turn out but I fancy Crouchy scoring at some point.
Ahead of the match, Pat from Leeds writes in saying: "If Newcastle don't win tonight they are in deep trouble, they will beat Boro, but get at most a point of Fulham and nothing out their last 2 away games. If they don't win tonight they might only be saved by the fact Hull wont pick up any more points."
Fancy a bet on tonight's game? I'm hoping Michael Owen can add to my fantasy football tally and get on the scoresheet and you can gets odds of him scoring first in a 2-0 win at 22/1 with SKYBET. A Newcastle outright win is priced at 4/5, a draw is 5/2 and a Pompey away win is 7/2.
So can Alan Shearer secure his first win as Newcastle boss or will Portsmouth crash the party to boost their survival hopes? Let me know your views by emailing me at email@example.com.
