Manchester City have announced the signing of Ilkay Gundogan from Borussia Dortmund on a four-year deal for an undisclosed fee.

The 25-year-old midfielder has made 157 appearances over the past five seasons for the German giants, helping them to a Bundesliga title and a DFB-Pokal.

"I'm thrilled to have signed for Manchester City," Gundogan told Man City's official website. "When I learned of City's interest my heart was set on coming here and things have moved very quickly.

"Now I have a new challenge and that is to achieve great things with City. The opportunity to work with a coach like Pep Guardiola is something I am really looking forward to and I am flattered to be the first signing the club has made this summer."

Gundogan is also a Germany international and has won 16 caps for the Nationalelf, though a knee injury has ruled him out of Euro 2016.
