From Match Weekly, December 13-19, 1979:
Not sure it would happen these days, but on 28th November 1979, Brighton & Hove Albion sent their first team to take part in a Daily Express national five-a-side tournament at Wembley Arena. The side defeated Rangers 1-0 in the first round, and then sweetly, ended the hopes of arch rivals Crystal Palace, winning 2-1. (It was the first win over Palace in ten attempts under Alan Mullery and provided the impetus for Brighton’s magnificent 3-0 win over the Eagles in the Division One game in December 1979).
In the Semi-Final, Brighton beat Mullery’s old club Tottenham Hotspur 2-1. Sadly, in the final, Sunderland proved too strong, triumphing 2-0 over the Seagulls.
