Manchester City have completed the acquisition of Dortmund midfielder, Ilkay Gundogan on a four-year contract.
The EPL club paid a sum of £20 million plus add-ons for the 25-year-old midfielder.
And despite dislocating his kneecap in May, the deal has gone through, with the Germany international the first signing under Guardiola at City.
“I’m thrilled to have signed for Manchester City,” he told City’s official website. “When I learned of City’s interest my heart was set on coming here and things have moved very quickly.
“I have loved my time with Borussia Dortmund and I would like to thank the club and the supporters for the five very happy years I spent there.
“They gave me a platform to play on and I became a better player because of the belief, patience and trust they showed in me.
“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.
“I can promise the City fans I will give everything to help us win titles both in England and the Champions League. These are exciting times.
“I have my best years ahead of me and I think we can achieve great things together. I can’t wait to begin this new chapter in my career.”
