In the 2006–07 season, Matmour continued to feature in the first team at the start of the season with SC Freiburg. He then set up for the first two goals in the match, in a 3–3 draw against Greuther Fürth on 22 September 2006.

But he made his return to the starting line–up against Hansa Rostock on 22 January 2007 and helped the club win 1–0. It wasn't until on 15 April 2007 when Matmour scored his first goal of the season, in a 3–0 win over 1. FC Köln. He later scored two more goals, coming against Karlsruher SC and TuS Koblenz, as SC Freiburg finished fourth place in the league. At the end of the 2006–07 season, Matmour finished the season, making 33 appearances and scoring 3 times in all competitions.
