a 6–0 victory at Windsor Park in the 2006 Setanta Sports Cup group stage. Since 2009, the rivalry has not been as intense as it once was, with the Big Two's domination of the domestic game decreasing as competitiveness across the league has improved. This is partly due to the resurgence of North Belfast derby rivals Cliftonville and Crusaders, and to a lesser extent Coleraine and Glenavon. In 2013, Cliftonville became the first club other than Linfield or Glentoran to win the league title since Portadown in 2002. In 2014, Cliftonville went on to retain the title for the first time in their history, with Crusaders then winning the 2014–15 title in convincing fashion, finishing 10 points ahead of runners-up Linfield. During this time, Glentoran lifted the Irish Cup in 2013, 2015 and 2020, however the club has gone 13 years without a league title, winning only three titles since the turn of the 21st century; in 2002–03, 2004–05 and 2008–09. Since then, they have finished as low as ninth place in the 2016–17 season. The last season in which the two clubs finished as champions and runners-up in either order was 2008–09, and they have not met in a major domestic cup final since 2006, when they contested both the Irish Cup and the League Cup finals. Sectarianism and violence Linfield are regarded as a 'Protestant club' and draw the vast majority of their support from that side of the community. The club has also been regarded as sectarian in the past, both in respect of its alleged employment policy and of the repeated behaviour of its fans. This sectarian reputation is partly the result of the actions of fans who have a history of anti-Catholic behaviour ranging from sectarian chanting on the terraces to outright physical violence. Part of the problem has been attributed to Windsor Park's location in a part of Belfast that was once predominantly Protestant. A relatively small number of local Catholics played for the club during the Troubles, which led to a widespread accusation that the club held a historical policy of not signing Catholic players. However, the existence of such a policy has been continually refuted: Sectarian tensions have long been a cause of conflict at football matches in Northern Ireland since the 1920s, and crowd trouble occasionally marred games involving Linfield throughout the twentieth century. One of the most notable such instances
