Christensen started his senior career with Herfølge Boldklub. He signed for English club Charlton Athletic from in June 2007 for an initial £250,000, which could potentially rise to £350,000.[1] He made his first Charlton appearance in a friendly match against Welling United. He joined Dutch team Heracles Almelo on a loan deal in January 2008.[2] In January 2009, he was loaned out to Danish club Lyngby BK until the end of the season. On 20 August 2009, he joined Italian Prima Divisione club Rimini Calcio on a permanent deal, without making a single first team appearance for Charlton. He signed a 1+1 contract.[3] In February 2010, Christensen signed a three-year contract with Haugesund FK in the Norwegian Premier League.[4]
He had a brief spell at SønderjyskE in spring 2011, but moved to HB Køge in April 2011.[5]
Christensen returned to HB Køge in the summer 2018.[6] At the end of the season, he retired and continued at Køge as a youth coach.[7]
