Sunderland signed defender Sotirios Kyrgiakos from Wolfsburg on Tuesday on loan for the rest of the season.

Kyrgiakos, 32, previously played with Liverpool and made 30 appearances in the Premier League. He left Liverpool last summer to join the German club.

"I am very happy to be here at Sunderland, which I know is a very good club with a very good coach," Kyrgiakos said. "I am very excited; very happy."

Capped 61 times for Greece from 2002-10, Kyrgiakos has also played for Rangers during his career, among other clubs.
