Editing UEFA Cup Winners' Cup (section)

==Format==
Throughout its 39-year history, the Cup Winners' Cup was always a straight knock-out tournament with two-legged home and away ties until the single match final staged at a neutral venue, the only exception to this being the two-legged final in the competition's first year. In common with other UEFA club tournaments, the [[away goals rule]] was applied when [[aggregate score]]s were tied. The format was identical to the original European Champions' Cup with 32 teams contesting four knock-out rounds prior to the showpiece final, with the tournament usually running from September to May each year. Following the influx of new UEFA member nations during the 1990s, a regular August preliminary round was added to reduce the number of entrants to 32.

Entry was restricted to one club from each UEFA member association, the only exception being to allow the current Cup Winners' Cup holders to enter alongside their nation's new domestic cup winners in order to allow them a chance to defend their Cup Winners' Cup title (although no club ever managed to do this). However, if this team also qualified for the European Champions' Cup, then they would default on their place in the Cup Winners' Cup and no other team would replace them. If a domestic cup holder also wins the Cup Winners' Cup in the same season, the domestic cup runner-up will take that association's berth.

On occasions when a club completed a domestic league and cup 'double' that club would enter the European Cup/UEFA Champions League and their place in the Cup Winners' Cup would be taken by the domestic cup runners-up. In 1998–99, the competition's final year, [[SC Heerenveen|Heerenveen]] of the Netherlands entered the Cup Winners' Cup despite only reaching the semi-final of the previous season's KNVB Cup. This was due to both KNVB Cup finalists [[AFC Ajax|Ajax]] and [[PSV Eindhoven]] qualifying for the recently expanded Champions League.
