Sunderland have turned to Manchester City's former director of football as they attempt to bring an end to their on-field struggles.
Wilson, who spent 10 years at City after a four-year stint at Southampton, will work alongside Moyes and chief executive Martin Bain as the club's new chief football officer, with the Black Cats looking to improve performance across the board.
Wilson said:"I am excited by the opportunity to join a club that is embarking on a journey of development and improvement.
"My role will be to ensure that we have the best practices, systems and people in place in order to give the club the best platform to achieve its goals.
"There is a great team of people at the club and I want to galvanise the good work that I know is already being done in order to ensure that we are doing everything we can to support the manager and chief executive in their aim of building a better football club."
