After returning from his loan spell at PSV, Berg only made 13 appearances the 2011–12 Bundesliga due to injuries and continued lack of form, scoring once. On 9 November 2012, Hamburger SV athletic supervisor Frank Arnesen stated that the club had to sell five players to raise funds after having invested heavily in new players in the previous summer, including Dutch star Rafael van der Vaart; one of these five players was said to be Berg. After these news, Berg was linked with a return to his former club IFK Göteborg.
