 He was an important key-player in Hammarby, especially the season 2009–10 with his feeling for finding the net, he was one of the greatest players in Sweden and very powerful.Gustav really was what you can call; a True Hero, not only because he took Hammarby to the final in 2007 with his 3 goals against Västerås, but also with his style of playing; He always plays his best for his team, he works hard, and he really is full of energy, as Stefan "Lillis" Jonsson once said.He is also a great skater, which he used well to get, as fast as he could, from the penalty booth to the bench on the other side.
