The 20-year-old striker agreed to the move after struggling to break into Christian Gross's squad this season. Streller is currently behind Christian Giménez, Julio Hernán Rossi, Hervé Tum and George Koumantarakis in the pecking order at the Saint Jakob stadium.
Streller, who scored 16 goals for Basel's reserves last term, is expected to make his debut against FC St. Gallen this weekend.
