Forsyth played 22 times for Scotland, including at the 1978 World Cup.[6] He captained Scotland once, against Switzerland in 1976.[8]
Managerial career
After his playing retirement, Forsyth was appointed manager of Dunfermline Athletic in 1982, although he relinquished the position within a year.[6] According to his assistant and successor Jim Leishman, Forsyth left his role as Dunfermline manager due to frustration with the club's part-time status: "I think the problem when Tam came to Dunfermline was that he was geared for full-time football at the time, and Dunfermline were part-time. The players would come in and Tam wanted that much on the Tuesday and the Thursday I think he forgot that these guys were part-time."[9] He then accepted a position as assistant-manager to former Rangers team-mate Tommy McLean at Morton in 1983.[6] Forsyth was appointed McLean's assistant at Motherwell then Hearts when McLean moved to these clubs in 1984 and 1994 respectively.[6]
On 14 August 2020, Forsyth died peacefully at home with his family by his side, at the age of 71.[10]
