Markus Halsti (born 19 March 1984) is a Finnish football defender and midfielder who plays for D.C. United in Major League Soccer and the Finland national team.
Starting his career in FC Viikingit before moving to HJK in the Finnish top league in 2003, he debuted in 2003. His 2005 season ended badly with a serious injury in the middle of the season. Same injury came later in the beginning of 2007 when he again missed half of the season due to this fracture in his right leg. This was also his last year in HJK as he signed to a Swedish club GAIS after a tip off from former Finnish national team coach Roy Hodgson as a bosman. However, before he ever had a chance to make a debut for GAIS he moved to the Allsvenskan rivals Malmö FF. Before signing with GAIS, he was on trial with Italian Atalanta and Leeds United. The Norwegian clubs Start and Molde IF, as well as a few unknown Danish clubs were also interested to sign him, but found him too expensive.
