Nathan Ake has signed a five-year-deal for Manchester City from Bournemouth for £41m.
The 25-year-old underwent his medical in Manchester on Wednesday, after City agreed a deal with relegated Bournemouth for the Ake.
The Dutch defender has become Pep Guardiola's second signing of the delayed summer transfer window, after the Cityzens secured the signature of Valencia winger Ferran Torres.
"City have been the best side in England over the course of the last decade," Ake told Man City's website.
"Coming here is a dream for me. This is a top side full of world-class players. Everywhere you look in this squad there are big names with international pedigree.
"Pep (Guardiola) is a manager admired across the world - what he's done in the game speaks for itself.
"The success he's had is unbelievable and the style of football he plays really appeals to me. I know I'm going to have to work hard to get into the side, but that's what I'm here to do."
In a post on his Instagram account on Wednesday night, Ake bid farewell to Bournemouth.
He wrote: "I want to say goodbye after a fantastic time at Bournemouth.
"I want to thank everybody involved with the club for everything over the past years! I've had a fantastic few years playing at Dean Court learning so much and creating some amazing memories!
"Thank you to all the staff and players who made me feel welcome from the first minute. Because of you I am now able to make this next step.
"Lastly I would like to thank all the fans who've been amazing to me from the minute I arrived. Unfortunately we couldn't bring this to a good end but I am sure we will see each other again in the future!"
