 The city's top sports club, Trabzonspor, was until 2010 the only Turkish football club outside İstanbul to win the Süper Lig (seven times), which was previously (until Trabzonspor's first championship title in the 1975–76 season) won only by the "Big Three" clubs of Istanbul, namely Galatasaray, Fenerbahçe and Beşiktaş.Due to Trabzonspor's success, the decades-old term "Big Three" which defined the most successful football clubs in Turkey had to be modified into the "Big Four".Trabzonspor is also one of the most successful Turkish clubs in the European Cups, managing to beat numerous prominent teams such as Barcelona, Inter, Liverpool, Aston Villa and Olympique Lyonnais.
