Lokomotiv Sofia signed Martin Kamburov on 9 January 2009 to a three-year deal. He was given the number 19 shirt. Kamburov had an excellent start to the season, netting 10 goals in just 6 games, including a spectacular hat-trick in Loko Sofia's away game against Levski Sofia on 11 April 2009 to help the team from the Nadezhda district secure a historic 3:0 win. Kamburov became the top scorer in the 2008/2009 season in the Bulgarian A Professional Football Group, managing 17 goals in total, a remarkable achievement given that he only played in half of the season's games.
