1992 FA Cup quarter final replay at Roker Park vs Chelsea.
We were 1-0 up but under a constant barrage of Chelsea attacks. Inevitably with seconds to go, they equalised and extra time beckoned. Whilst the Chelsea fans were still celebrating, we won a corner and from nowhere, Gordon Armstrong powered a header into the bottom corner from what seemed like the edge of the area.
Unforgettable and back when The FA Cup meant something.
