The one that comes to mind is the 4-4 but it loses points because it was just a random league game in February.
5-1 v Spurs meant nothing to me because we'd just been relegated but the 3-0 and 1-0 (Ritchie) wins over Man Utd felt great. So did this year's 2-1 over Man City.
A lot of the decade was just a blur of Pardew, Carver, protests and Championship nonsense, so I guess my #1 was the 5-1 against the mackems.
