The 1990/91 season was the 94th season of Scottish league football.
Ally McLeod left the club and Davy Wells took over as interim manager until George Burley, a native of Cumnock, was appointed as permanent manager in January 1991.
The club reintroduced full time football but results didn’t deliver the expected success finishing a poor 12th in the league survival focusing on two wins out of their last four, including a 1-0 over Kilmarnock, to see off relegation.
Off it, the club slipped into another financial crisis. Nevertheless Ayr did manage a Cup Final appearance - their first ever - in the Centenary Cup, a one-off competition for clubs outwith the Premier League to celebrate the centenary of the Scottish Football League.
The result was an agonising defeat for Ayr on penalties after extra time.
Ayr United legend Ally McLeod finally bowed out of football management and was succeeded by George Burley in his first job in management.
