from Hamburger SV on a three-year contract.
Schalke sporting director Horst Heldt at the weekend said that "all parties have reached agreement on the details" and all that was missing were the signatures. Those arrived on Wednesday with the official confirmation duly dispatched.
"Up until his serious injury, Dennis' performances were more than satisfactory," said Heldt. "His versatility helped us overcome personnel shortages during the first half of the season. He identified with the club and the region from the moment he got here."
Aogo, currently sidelined due to injury, swapped Hamburg for the Veltins Arena on an initial loan deal at the end of August. The 27-year-old defensive all-rounder made twelve league appearances, ten from the start, before tearing a cruciate ligament in his right knee in training at the end of November.
Feeling the faith
"I felt a great deal of faith placed in me from this club the very minute I arrived here," said Aogo, who is at home across the back line and in midfield, and is naturally left-footed. "That is why I'm happy and grateful that Schalke are sending me such a signal with this contract. It motivates me even more to get fit again soon."
