The club’s official website unveiled the new signings and confirmed that they will be tied to HSV until 2013.

The statement also said that the Brazilian defender, 23, has been hired worth €6.2m while Jansen, 22, has been brought worth €8m.

Hamburg made a lot of investments in the transfer market as they offloaded Mohamed Zidan and Vincent Kompany and bought Silva, Jansen and Ivan Petric.
