Fredrikstad's comeback from obscurity is largely attributed to manager Knut Torbjørn Eggen, who introduced a degree of professionalism the club had previously lacked. During his tenure, from 2001 until the end of 2006, the son of Rosenborg's successful former coach led the team to their first title in more than two decades. In 2002, they were promoted from the 2. divisjon to the 1. divisjon, and in 2003, their centenary year, Fredrikstad finished second, earning promotion to the top division. Although struggling to maintain their form through an entire season, Fredrikstad have managed to retain their spot three times, and in 2006 they won the Norwegian Cup for the eleventh time in their history. They came 2nd and won silver in the 2008 season, but relegated after a poor season in 2009 to 1. divisjon. They eventually got promoted back to Tippeligaen through playoffs in November 2010 by first beating Løv-Ham 2–0, then Hønefoss BK with a stunning 8–1 goal difference over two matches.
