Chelsea sporting director Frank Arnesen will join Hamburg at the end of the season, the Bundesliga club have confirmed.
Arnesen, 54, will be appointed Hamburg's sporting director on a three-year contract and will be joined in Germany by Chelsea's chief scout Lee Congerton.
Chelsea announced in November that Arnesen would be leaving the club when his contract expires and Sunday's news marks the end of Hamburg's search for a sporting director, having recently been turned down by Matthias Sammer.
"Hamburg is a special club with a long tradition and fantastic infrastructure," Arnesen said. "I am convinced that with the strength we have and the right decisions we can develop something big."
He joined Tottenham in 2004 but was prised away by Chelsea after only 12 months in North London. Arnesen was asked to increase the flow of academy graduates into the Blues first team.
"I am delighted that we have found this fantastic solution," Hamburg chairman Ernst-Otto Rieckhoff said. "Frank Arnesen has not only the aptitude that is very meaningful to us for our future thanks to his experience as a manager at top clubs in Europe, but in particular due to his focus on youth development."
Hamburg are currently in seventh place in the Bundesliga.
