Hamburger SV has taken on another young player from Chelsea, signing 19-year-old Dutch defender Jeffrey Bruma on a two-year loan deal.
Since Frank Arnesen arrived in Hamburg to become director of sports, the Bundesliga club has signed four young players from his former club.
The other three are Michael Mancienne, Gokhan Tore and Jacopo Sala.
Bruma is expected to step in for Joris Mathijsen, who has moved to Malaga. Arnesen says Bruma is "super talented."
