AFP, Berlin :
International striker Nicolai Mueller has left Mainz to join Hamburg on a four-year contract worth an estimated 4.5 million euros.
The 26-year-old, capped twice by Germany, had been with Mainz since 2011, scoring nine goals last season.
Mueller becomes Hamburg’s fourth close-season recruit after Swiss midfielder Valon Behrami (Napoli), Hungarian Zoltan Stieber (Greuther Fuerth), and German striker Pierre-Michel Lasogga, on loan last season from Hertha Berlin.
