Trouble has arisen during matches between Istanbul rivals Galatasaray and Fenerbahçe. However, the Turkish Football Federation has tightened security to try to contain the hooliganism. During the 2005 Turkish cup final between Galatasaray and Fenerbahçe, 8,000 police, stewards and officials were employed to prevent violence. In 2006, the Turkish Football Federation introduced new measures to combat the threat of hooliganism and have made new regulations that allow the Professional Football Disciplinary Board to fine clubs up to YTL 250,000 for their fans' behavior. Repeat offenders could be fined up to YTL 500,000. Despite reports from the Turkish Football Federation, the Turkish police believe that football hooliganism is not a major threat and is "isolated incidents".
