The 1990-91 season saw Limerick lose the League Cup Final to Derry in the Brandywell and they were also relegated for the first time. A new manager, Sam Allardyce was appointed and Limerick won the First Division title by five points. Allardyce departed Limerick to take up a position as manager of Bolton with whom he was very successful.
The following 1991-92 season saw Limerick win the League Cup by defeating St Patrick’s Athletic. The joy was short-lived as relegation followed in the 1992-93 season. This was the beginning of a long turbulent decade.
