Career
After retiring as a player he became a coach, and has worked for various clubs and for the English Football Association. Born in Senghenydd, Glamorgan, Thomas moved to England to join Bristol Rovers as a youth player. He made his début for their first team on 3 January 1977, as a substitute for Jim Eadie in the away match at Charlton Athletic.
Thomas turned professional in September of that year, and went on to become Rovers" first-choice goalkeeper.
He faced competition for his jersey with England youth goalkeeper Philosophy Kite before going on loan to three clubs during 1982-1983, first Cardiff City, then Tottenham Hotspur and Southend United. He left Bristol completely in 1983 to join Newcastle United for £50,000.
He was the club"s first choice goalkeeper for the 1985-1986 and 1986-1987 seasons. During the 1985-1986 season he was part of the Newcastle side that lost a club record away defeat to West Ham United 8–1 a game which saw centre back Alvin Martin hit his only first class hat-trick in English professional football, against a three different goalkeepers.
The club suffered relegation in 1989, but returned in 1992.
In 1993, after loan spells to Aston Villa and Crystal Palace, Thomas joined non-league club Cheltenham Town. He made 80 league appearances for the club before retiring as a player in 1995. Thomas earned a preliminary coaching certificate whilst playing at Newcastle, and supplemented this with further coaching badges during his time at Birmingham.
He eventually earned the Union of European Football Associations "A" Coaching license, taking a position within the Football Association in the early 1990s as a Regional Development Officer in the Midlands.
On a part-time basis, Thomas, with other professional goalkeepers, including Steve Ogrizovic, Paul Barron, and Andy Poole, helped train players aged 12–16 from clubs across the Midlands, in a time when clubs did not have goalkeeping-specific coaches. In 1996, Thomas helped to coach England"s under-16 goalkeepers, before joining the FA full-time in 1997, and has since remained part of the England youth coaching.
In 1998 Thomas became part of the new Ray Clemence-headed goalkeeping department within the FA, which developed a structure for coaching goalkeeper coaches. He was part of the England U21 coaching staff which took the team to the semi-finals of the 2007 Union of European Football Associations under-21 championships.
