Provided by Wikipedia David Hay (born 29 January 1948) is a Scottish former football player and manager. He broke into the Celtic team in the late 1960s, as one of a generation of players who continued a highly successful era for the club. A contract dispute between Hay and Celtic led to him being transferred to Chelsea in 1974. He played in over 100 league games for Chelsea, but was forced to retire in 1979 due to a detached retina. Hay appeared in 27 international matches for Scotland, and was selected for their 1974 FIFA World Cup squad.
After retiring as a player, Hay entered football management with Motherwell in 1981. He led them to a promotion in 1981–82, but left the club at the end of the season. He was then appointed Celtic manager in 1983, and enjoyed some success as they won the 1984–85 Scottish Cup and the Scottish league championship in 1985–86. In the 1990s he returned to Celtic as Chief Scout and later assistant general manager.
