Sunderland have completed the signing of striker Steven Fletcher from Wolves for an undisclosed fee.
The 25-year-old has signed a four-year contract at the Stadium of Light and will be available for the Black Cats' Premier League game against Reading on Saturday.
Manager Martin O'Neill told safc.com: "It has been no secret that we needed to strengthen our attacking options and Steven has a proven track record of scoring goals."
Fletcher has been O'Neill's top target in his bid to bolster his attack following the departures of Nicklas Bendtner and Asamoah Gyan, with Louis Saha already signed up earlier this month.
O'Neill added: "I'm delighted. I've just come from the training ground and I'm delighted it's all gone through.
"I think Steven will be terrific for us. He's underrated, but not by me.
"I think he's capable of scoring goals and linking play which is very important to us and I think now at 25 years of age he's got room to improve and really get better.
"Wolves lost their Premier League status last season but I think he's very good and I think he's improving.
"He hasn't played that much. He had a setback a few weeks ago so in terms of fitness he didn't train with us today but I'll assess him anyway.
"I'm delighted to have him for the next few seasons."
