Gelsenkirchen, Germany (SportsNetwork.com) - Schalke have completed the permanent signing of defender Dennis Aogo from Hamburg for an undisclosed transfer fee, the club announced on Wednesday.

Aogo has been on loan at the club since the beginning of the campaign, but will remain with the Royals Blues until 2017 after putting pen to paper on a three-year contract.

Aogo made 16 appearances in all competitions for Schalke before tearing his anterior cruciate ligament in training in November.

Despite the injury, Schalke general manager Horst Heldt was impressed with Aogo's performances before his injury.

"Up to his severe injury we were more than satisfied with Dennis' performance," he said. "His versatility helped to bridge personnel shortages."

"I felt from the beginning great confidence from the entire club," Aogo added. "Therefore, I am happy and grateful to sign this contract with Schalke 04. That motivates me even more to do everything to be fit again soon."
