Bayer 04 Leverkusen have confirmed the signing of Turkish international Hakan Çalhanoğlu from Hamburger SV in a reported €14m deal.
The attacking midfielder has agreed a five-year contract with the Werkself, who finished fourth in the Bundesliga last term. Hakan, 20, enjoyed a strong debut season in the German top flight, scoring 11 goals in 32 games as HSV avoided relegation via a play-off against SpVgg Greuther Fürth.
"I had a great time at Hamburg, but I am looking to make the next step at Bayer," said the former Karlsruher SC player, capped five times by Turkey. "Leverkusen have a great team and are regularly involved in European competition. To play in the UEFA Champions League and compete for a top spot in the Bundesliga is a great challenge for me."
Leverkusen sporting director Rudi Völler said: "His qualities as a playmaker and goalscorer make him a huge asset for Leverkusen. We have gained a creative element and are much harder to predict with him in our team."
Hamburg have immediately reinvested by making permanent the loan transfer of Pierre-Michel Lasogga from Hertha BSC Berlin. The 22-year-old registered 13 goals in 20 Bundesliga outings for HSV in 2013/14 and was poised to become part of Germany's FIFA World Cup squad before struggling with injury problems towards the end of the campaign.
Leverkusen enter the UEFA Champions League at the play-off stage on 19/20 August.
