The Sarajevo derby (Bosnian: Vječiti derbi, Sarajevski derbi) is a match between rivals from Bosnia and Herzegovina's capital city FK Željezničar Sarajevo and FK Sarajevo, the two biggest and most popular clubs in the country, during which fans usually create a competitive atmosphere with big flags, paper rolls, scarfs and loud chanting. It is not uncommon to see members of the same family on opposite sides, not speaking to each other on the day of the derby, with opposing fans engaging in mutual provocations at the end of the match, eagerly awaiting the next confrontation although, in recent years, this has led to clashes between some younger fans.
