Although he has no formal involvement in football any more, he still turns out for the Posh Legends, the veteran side of Peterborough United.

[2] Gallagher, a forward, began his career in the youth team at Guyhirn where an impressive appearance in a youth cup final against Wisbech Town in 1973 saw him switch clubs to the Fenmen, making his first-team debut at the end of the 1973–74 season in the first leg of the county cup final against Willingham.

Despite a successful season, he left at the end of it, returning to Wisbech Town debuting in the 1–0 Eastern Counties League victory at Tiptree United on 20 August 1983.

[4] He moved on to join Irish side Drogheda United, helping them defeat Athlone Town 3–1 at Tolka Park on 5 January 1984 to lift the League of Ireland Cup.

He found opportunities limited at Molineux due to the prolific partnership of Steve Bull and Andy Mutch, but did play at Wembley in their victory in the Associate Members' Cup Final in May 1988.
