Sunderland have completed the signing of Blackpool midfielder David Vaughan on a free transfer.
Vaughan, 28, had been offered a new contract by the Tangerines but turned them down in order to remain in the Premier League on a three-year deal at the Stadium of Light.
The Wales international was one of the stars of Blackpool's rollercoaster season in the top flight, starting 35 games. Vaughan, who began his career at Crewe Alexandra before spending a season at Real Sociedad under Chris Coleman, joined Blackpool in 2008 and spent three seasons with the club.
He is Steve Bruce's ninth summer signing, following Wes Brown and John O'Shea in a busy 24 hours. He joins fellow midfielders Ahmed Elmohamady, Craig Gardner and Sebastian Larsson among the newcomers in a department which this summer has lost Jordan Henderson to Liverpool, Bolo Zenden at the end of his contract and Sulley Muntari following a disappointing loan spell.
Bruce has also landed goalkeeper Keiren Westwood and O'Shea and Brown at the back and strikers Connor Wickham and Ji Dong-won.
Sunderland manager Steve Bruce told the club's official website: "David was excellent throughout last season, including both games against us, so it's only natural that he caught the attention of a number of top clubs.
"We're delighted that he sees his future at Sunderland. His experience, grit and energy in midfield will be valuable assets to us and we're now looking forward to him joining up with the squad for pre-season training."
Vaughan added: ''I had a good season last year with Blackpool and there's no reason why I can't do that here. Obviously, there is a bit more expectation on Sunderland and the players, but hopefully I can prove to the fans that I'm good enough to play for the club.
''I could have possibly gone to a different club with less expectation, but I wanted to try to push myself and prove that I am good enough to be here.
''It took me a long time to get to the Premier League and I didn't want to drop out after one season, so it was one of the main factors of coming to Sunderland, and the size of the club was also a big factor.
''The club is really well supported and the structure and the training facilities are top drawer, so from a football point of view, it was my best option.''
