Chelsea starlet Slobodan Rajkovic has joined Hamburg on a four-year deal.
The Serbian international centre back has been on the books at Stamford Bridge since 2007, when he moved for a then world-record fee paid by a club for a player under the age of 18 (€5.2 million).
After successful loan spells with PSV, FC Twente and Vitesse in Holland, Chelsea boss Andre Villas-Boas was hoping to include the 22-year-old in first team activities at Stamford Bridge after a successful pre-season with the club.
However, continuous difficulties with securing a work permit for the player have seen Chelsea finally give-up on the player, who moves to the Bundesliga having failed to make a competitive appearance for the Blues during his time in west London.
Rajkovic becomes the fifth Chelsea youngster to join the German side following former sporting director Frank Arnesen's appointment with HSV, and manager Michael Oenning now boasts another player alongside Michael Mancienne, Gokhan Tore, Jacopo Sala, Jeffrey Bruma.
"He is tall and an uncomfortable opponent who can scare other players," said Oenning.
"He is bringing a quality we do not have and we need right now. On top of that he is left footed."
Chelsea wished the player all the best in a statement released on their website earlier today.
