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.”
