Football Association of Norway and Vital Eiendom. From the 1960s till the 1980s and a short period in the end of the 1990s Bislett Stadium was Vålerenga's home ground. Bislett Stadium also hosted speed skating and track and field events in addition to football, and hosted the 1952 Winter Olympics. Poor conditions and maintenance of Bislett forced Vålerenga to move to Ullevaal and a groundshare with FK Lyn. After Vålerenga moved from Bislett Stadium plans for building their own ground were conceived, but poor results on the field combined with financial problems kept those plans at bay for a few years. After the second place in 2004 and the league title in 2005 as well as business man John Fredriksen's deletion of the club's debt in 2003, the talks of building a ground for Vålerenga resurfaced. Supporters Vålerenga has traditionally drawn support from the area around Vålerenga, Oslo and various other places on the east end of Oslo, although today these lines are largely blurred and the club has supporters all over Oslo and the surrounding areas. Up until the early 90s, Vålerenga's supporters were loosely organised. The supporters were sometimes referred to as Apeberget, but this is actually a misnomer from a journalist. An independent supporter club called Klanen ("The Clan") was founded in 1991. It has around 10,000 members today. The senior team of Vålerenga has reserved shirt number 12 for their supporters. Vålerenga's supporters, and specifically Klanen, are widely considered to be the best football supporters in Norway. Rivalries Vålerenga's main rivals include Lillestrøm, Ham Kam, Kongsvinger, Brann and Lyn. Since the 90s, the main supporter club has actively worked hard for social issues and against hooliganism. Despite this, as recently as 2019, isolated individuals within the club's support have engaged in disruptive and dangerous activities during live matches. In the 2014 season, Vålerenga gathered an average attendance of 9,756 at their home matches, ranking them fourth in Norway with regard to attendance.
