Football Club Koper, commonly referred to as FC Koper or simply Koper, is a Slovenian football club based in Koper that competes in the Slovenian PrvaLiga, the top flight of Slovenian football. The club was founded in 1920. Koper is one of five Slovenian clubs that managed to win all three domestic trophies (league, cup and supercup). The club's home ground is Bonifika Stadium, which has a capacity of 4,047 seats. History The club was formed as Circolo sportivo Capodistria in 1920. The team was made up of students, workers and fishermen. Its colours were black and white. In 1928, the club was renamed as Unione sportiva Capodistriana. Six years later, the club was renamed as Libertas. After World War II, the club became part of a larger sports association and renamed as Aurora. By 1948, there were five clubs operating in the Koper area: Aurora, Meduza, Partizan, Edilit, and Adria. In 1955, Aurora and Meduza merged, creating NK Koper. The club played under this name in different Yugoslav leagues until 1991 and was one of the most successful Slovenian clubs. After Slovenia's independence, the club played in the Slovenian PrvaLiga. At the beginning of the 1990s, the club was achieving mid-table success. By the end of the 1990s, the club had been relegated to the second division twice, had serious financial problems, and renamed as FC Koper. With the advent of the new millennium, Koper consistently achieved positions in the upper half of the table. In 2002, they competed in the 2002 UEFA Intertoto Cup, their first international competition. Two years of mid-table anonymity and significant financial difficulties followed, in part because the former owner, Georg Suban, left substantial debts to the club and took half of the team with him when he moved to the other Slovenian PrvaLiga team, Mura. The fans took control of the club and tried to improve its finances to save it from going bankrupt like three other major Slovenian clubs (Olimpija, Mura and Ljubljana), with reasonable success. In the 2005–06 season, Mladen Rudonja returned to the club and brought with him the Serbian-American businessman Milan Mandarić, who paid off all the remaining debts. After the first half of the season, before the arrival of the new patron, Koper was battling against relegation, but in the second part of the season, with a new coach, Milivoj Bračun, the club started an unbeaten run that
