The club has delivered more players to professional hockey leagues around the world than any other hockey team in Norway. For the 2004/2005 season, Manglerud Star played in the first division after financial problems, being relegated from Eliteserien, but after the qualification league at the end of the season, they were back at the top level for the 2005/2006 season. After competing against the 05/06-finalist Trondheim in the Eliteserien qualification, which was surprisingly low-levelled at that season, they were relegated to the level 2-league first division for 2006/07. Many people claim Mats Trygg to be the best M/S player ever, he was playing for Färjestads BK in Sweden during the 2004/2005 season, but plays the 2005/2006 season for Iserlohn Roosters in Germany, together with his best friend and partner in the national team of Norway Martin Knold. In 2004, the city of Oslo provided funding for a new sports hall, which also includes a football arena beside the hockey rink.
