Heaney came on as a substitute with Saints 1–0 down, and with four minutes left he prodded home a loose ball after a save by Pavel Srníček from Gordon Watson's header.
"[6] Heaney made 61 league appearances for Southampton in two and a half seasons, scoring five goals,[3] before being sold for £500,000 to First Division (second-tier) club Manchester City in November 1996.
He was part of the Charlton side that faced Sunderland in the dramatic 1998 First Division play-off final, a match they won 7–6 on penalties after a 4–4 draw to gain promotion to the Premier League,[7] while Manchester City were relegated to the third tier.
After two and a half seasons during which he started just 16 matches in all competitions, Heaney spent the last few weeks of 1998–99 on loan at First Division Bristol City before signing for Darlington in August 1999 on a free transfer.
[12] He returned to English football with Plymouth Argyle, managed by Paul Sturrock who had signed him for Dundee United, but lasted less than a year of his 18-month contract before recurrent knee problems forced his retirement.
