He told the Sunderland Echo: "Managing Newcastle has never been my dream as a boss.
"I'm in football management now and I look for the right job more than anything else.
"And this opportunity at Sunderland has got everything I want - the infrastructure, the fan-base, an ambitious chairman and an ambitious new owner.
"I don't need anything else - I've got everything here. Everything you look for as an ambitious manager is here at Sunderland.
"It's a big club with a big history, a long tradition, and the potential to really go places.
"All the off-field components are there, and we need to build a team now to really take things forward."
