"I spoke to a number of clubs but once I spoke to manager Mark Hughes my mind was made up," he told the clubs official website.
"These are exciting times for me. I've had a couple of difficult years but I've no doubt that I can still do it.
"Given a fair crack of the whip here I'm sure I can get back to my best and take this club forward.
"It has been a busy couple of days but what a fantastic move for me, I can't wait."
