Manchester City have kicked off their summer spending spree with the signing of Ilkay Gundogan from Borussia Dortmund.

Gundogan had been linked with a transfer for some time but doubts were raised over the likelihood of a move this summer after he dislocated a knee cap in May.

The injury meant the playmaker missed out on a place in the Germany squad for Euro 2016, having also failed to earn selection for the 2014 World Cup due to a back problem.

Despite his fitness issues, Gundogan is regarded as one of Europe’s best midfielders and scored in Dortmund’s Champions League final defeat to Bayern Munich in 2013.

The 25-year-old becomes the first signing of the Pep Guardiola-era after agreeing a four-year deal at the Etihad for a fee of around £20m.

Gundogan admits he is excited about starting the next chapter of his career and says he could not turn down the chance of working with Guardiola.

“I’m thrilled to have signed for Manchester City,” Gundogan told the club’s official website.

“When I learned of City’s interest my heart was set on coming here and things have moved very quickly.

“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.”

City are currently the 2.88 favourites to win the 2016-17 Premier League title and 13.00 to secure a maiden Champions League crown.
