Derby County, promoted to the First Division in 1969 after a lengthy absence, emerged as a force during the 1970s, winning the league title in 1972 under the controversial but effective management of Brian Clough, and again in 1975 under Clough's successor Dave Mackay. Clough, after a disastrous 44-day spell as Don Revie's successor at Leeds United, enjoyed even greater success at Nottingham Forest, taking the East Midlands club to promotion in 1977, the league title and League Cup in 1978 and to a further League Cup and the European Cup in 1979, before retaining their European crown in 1980. During this run of outstanding success, Clough also shelled out British football's first £1million transfer fee for the Birmingham City forward Trevor Francis, who signed for Forest in February 1979. Also among his acquisitions was the goalkeeper Peter Shilton, who went on to win a record of 125 full caps for England.
