Paul Cook - who had been an early favourite to replace Chris Coleman at Sunderland - has signed a new four-year deal with Wigan Athletic.
Wigan have moved quickly to secure the future of the in-demand manager on improved terms.
Cook led Wigan to the League One title with 98 points and his work there has led to him being linked with a host of top jobs.
His name was high in the betting for the vacant manager’s job at the Stadium of Light but his future remains at Wigan.
Latics chairman David Sharpe said: “I’m absolutely delighted to see Paul commit his long-term future to Wigan Athletic.
“He has been the main reason behind our success this year.
“I can speak on behalf of everyone associated with Wigan Athletic in saying this is fantastic news.
“Paul is a serial winner - to win the League One title with 98 points, and beat Bournemouth, West Ham and Manchester City to reach the FA Cup quarter-finals in his first season in charge is unbelievable.”
Cook added: “I have loved every minute of my time here.
“I sit here very proud of the success we have enjoyed this season, but in equal measure aware of the challenges we face moving forwards into the Championship – an exciting challenge.”
Sunderland will swap divisions with Wigan after finishing bottom of the Championship under Coleman.
