The UEFA Cup, also known as the Europa League, is Europe's second-tier competition. Clubs which finish below the Champions League positions in Europe's leading nations are admitted, as too are cup-winners. Teams which finish top of the league in smaller European nations are given the chance to qualify for the Champions League, but are admitted to the Europa League / UEFA Cup if unsuccessful. Although the tournament has been mocked by English football fans, it remains an important tournament, giving the middle-ranking teams from top nations and top-ranking teams from other nations the opportunity to play each other. The most successful team in UEFA Cup history is the Spanish side Sevilla, which won its fourth final with victory over Dnipro in May 2015. The most recent English winner of the trophy is Chelsea under Rafa Benitez in 2013.
