The competition began on 20 November 1990 and ended with the final on 7 April 1991 at Wembley Stadium.
In the first round, there were two sections: North and South. In the following rounds each section gradually eliminates teams in knock-out fashion until each has a winning finalist. At this point, the two winning finalists face each other in the combined final for the honour of the trophy.
Arsenal, Liverpool. Tottenham, Manchester United and Aston Villa opted out of this competition.
