My pick:
1. 2-0 vs Lincoln, Play-off Final, Millennium Stadium
Probably no.1 as it's freshest in memory, but if you go up what a place and game in which to do it
2. 1-0 vs Bury 90/91 Gigg Lane
Promotion to the Promised Land
3. 3-1 vs Birmingham 93/94 Roots Hall
Fat Judas thrashed on his return
4. 0-3 vs Liverpool 78/79 Anfield
The Kop singing "Southend" made me cry, and they were not being patronising
5. 1-0 vs Wolves 86/87 Roots Hall
Crucial win against promotion rivals at an electric Roots Hall with "loads" of Wolves all over the place
6. 1-0 vs. West Ham 92/93 Roots Hall
Fat Judas leads us to victory (oh so sweet victory). Roycie makes crucial save from David Speedie just before the end
7. 5-1 vs. Port Vale 80/81 Roots Hall
Scintillating first 30 minutes of the game sees us 5-0 up
8. 2-1 vs. C********r 86/87 Layer Road
Fantastic long and mazy dribble by Peter Johnson before he unleashed a 30 yarder to beat Col U in a promotion season
9. 3-2 vs Wigan 87/88 Roots Hall
Superb 2nd Half comeback with two subs (McDonough and Ling) scoring before memorable David Crown run and scorching shot to give us victory from the jaws of defeat
10. 1-0 vs Watford 78/79 Roots Hall (FA Cup)
The replay victory that gave us the tie against Liverpool. All the nations press were ther to see Watford beat us to set up a clash with Liverpool, because the press loved them due to Elton John etc. Andy Polycarpou cracker gave us victory.
Worse game: Tuesday night away to Sunderland 0-7 in 87/88 (the only number we didn't concede that year between 0-8 was 5). To this day I still swear that there 5th was handball by Eric Gates!
