John Frederick Byrne (born 1 February 1961) is a former professional footballer who played for the Republic of Ireland and various clubs in England and France in the 1980s and 1990s.
Born in Manchester, Lancashire, Byrne began his career with York City and came to the attention of Queens Park Rangers during the League Cup match between the sides in 1984.
With Sunderland, he had the distinction of scoring in every round of the 1992 FA Cup except the final, which Liverpool won 2–0 with goals from Michael Thomas and Ian Rush, although he revealed in a pitch-side interview following the game that he was mistakenly handed a winner's medal.
Byrne played Sussex County League football for Shoreham[2] before spending two seasons as joint manager with Russell Bromage.
His best day in a green shirt came when he scored two fine goals in the 3–1 win over Turkey played in the BJK İnönü Stadium in Istanbul as part of the qualification for Euro 92.
