Manchester City have completed the signing of Nigel de Jong on a four-and-a-half year contract.
The Dutch international had been in talks with City recently after they agreed a fee with Hamburg on Monday for his services.
De Jong becomes City's third signing of the winter transfer window following the arrivals of Wayne Bridge and Craig Bellamy.
The fee for the 24-year-old former Ajax midfielder, who has won 29 caps for his county, remains undisclosed.
De Jong links up with former Hamburg team-mate Vincent Kompany at Eastlands after City swooped for his signature last summer.
De Jong has spent the past three years with Hamburg and feels that joining Mark Hughes' ambitious side is the next step in his career.
"I feel very good and for me it is the next step in my own career after three years in Germany," he told the club's official website. "I hope to be successful here.
"The ideas and the planning behind this club are very hopeful and it's a new adventure so I'm delighted to be here right now.
"The stadium looks great and I think it can only be better when it's full of people.
"I'm looking forward to playing here and everybody knows that the Premier League is maybe the biggest competition in the world."
