Marin's only goal of the Bundesliga campaign came on 18 February 2012, when he opened the scoring in the ninth minute of a 3–1 derby victory over Hamburger SV at the Imtech Arena. In Marin's final game for Bremen, he provided the telling ball for Markus Rosenberg's goal, but this was not enough as his side succumbed to a 4–1 away defeat to VfB Stuttgart on 13 April. Marin ended his time with the Bremen club after scoring eight goals in 87 Bundesliga appearances.
