Brian Clough

Brian Clough won the First Division title with Nottingham Forest in 1978 — their first ever — and then won the European Cup in 1979 and 1980, making Forest one of only three clubs to win the European Cup in consecutive seasons. He had previously won the First Division with Derby County in 1972. Forest were the first team promoted from the second division to win the European Cup the following season. Clough achieved all of this without a significant transfer budget and through sheer psychological authority over players — a management style that has never been replicated.
