Ranking The teams were ranked according to their 1992 UEFA seeding coefficients, which took into account performances in European competitions from 1987–88 to 1991–92. Each club and national association had a seeding coefficient calculated (total points divided by total matches), with both values added together to determine the club's final coefficient. This ranking then determined the round each team would enter.
