Norwich City defender Michael Turner is determined to show Sunderland what they've lost.
Turner plays his first game at the Stadium of Light since he was sold to the Canaries for £2million last summer.
Turner, 29, said: "I had a great first season but in my second year I picked up a bad injury.
"It was a massive setback and after that my time there was disrupted by one injury after another.
"I played a few good games for them and we had some big wins, but their fans never saw the best of me.
"I don't feel I have anything to prove - I just want to show them that I'm a pretty good player."
