Niall Quinn has decided to leave Sunderland to return to Ireland to concentrate on his family and business interests outside football. Quinn, who played for Arsenal and Manchester City before settling in Sunderland, quit his role as chairman in October 2011 to concentrate on developing the club internationally.

The former Ireland international said on the club’s official website: “I’ve had the most amazing six years and it gives me a huge sense of pride to see where Sunderland is today. “Sunderland is in an incredibly fortunate position to have a hugely talented team of people leading the football club right now.

“There is a tremendous amount of energy about the place and the Board and the executive management team are a dynamic and committed group, who hold the best interests of the club at the core of all they do. “Everything is in place for Sunderland to really make a statement, which was always my aim. “From a football perspective, securing the services of Martin O’Neill has been an absolute highlight. In Martin we have a man that understands the region, the club and the unique place it holds in the lives of its supporters and I am confident that he will harness the immense passion that exists here and take us to new heights. “As for the great Sunderland fans, I would like to thank them for the trust they placed in me. Back in 2006 I had no business experience and little formal education and yet the fans backed me and believed in what I was trying to do.”

Quinn was responsible for bringing the current owner Ellis Short and manager Martin O’Neill to the club. The Black Cats are currently 9th in the Premier League and are in the quarter final of the FA Cup.
