Distribution Redistribution rules A UEFA Cup place is vacated when a team qualify for both the Champions League and the UEFA Cup, or qualify for the UEFA Cup by more than one method. When a place is vacated, it is redistributed within the national association by the following rules: • When the domestic cup winners (considered as the "highest-placed" qualifier within the national association) also qualify for the Champions League, their UEFA Cup place is vacated, and the remaining UEFA Cup qualifiers are moved up one place, with the final place (with the earliest starting round) taken by the domestic cup runners-up, provided they do not already qualify for the Champions League or the UEFA Cup. Otherwise, UEFA forgot to establish a rule, so each association decided how to assign this place. • When the domestic cup winners also qualify for the UEFA Cup through league position, their place through the league position is vacated, and the UEFA Cup qualifiers which finish lower in the league are moved up one place, with the final place taken by the highest-placed league finisher which do not qualify for the UEFA Cup yet. • A place vacated by the League Cup winners is taken by the highest-placed league finisher which do not qualify for the UEFA Cup yet. • A Fair Play place is taken by the highest-ranked team in the domestic Fair Play table which do not qualify for the Champions League or UEFA Cup yet.
