The Belgian international playmaker will wear the no.17 shirt and follows in the footsteps of Raheem Sterling, Fabian Delph and Nicolas Otamendi in transferring to the Etihad Stadium this summer.
De Bruyne said: "I want to reach the highest level possible as a player and I think the most important thing is that at the end of the season we can be happy and maybe have some titles.
"I think this is the most important for the Club, the players and for the fans of course."
Manager Manuel Pellegrini said: “We are very happy to have added Kevin to our team and I have no doubt that he will be a big success on his return to the Premier League.
“It takes a special footballer to improve our squad and I have no doubt that Kevin is certainly one of those – he has all of the mental, physical, tactical and technical attributes required to fit straight in.
“We like to play attractive, attacking football and bringing in a player like De Bruyne will only aid us as we fight on four fronts.”
Kevin's first interview as a City player
Starting out on his professional career at Genk in his native Belgium, Kevin made his first-team debut in May 2009 and established himself in the first-team at the Pro League outfit.
In his second full season as a regular, De Bruyne was an integral member of Genk’s title-winning side, making 17 assists in all competitions and scoring six goals.
His reputation as the league’s “assist king” was further enhanced in the following season where he made another 15 and bettered his goal tally, prompting interest from Chelsea who took him to Stamford Bridge in 2012.
Kevin spent his first season as a Chelsea player on loan at Werder Bremen where he got his first taste of Bundesliga football, making 34 appearances, scoring 10 goals and laying on 10 goals for teammates.
That would prove to be a mouthwatering preview of what was to come in Germany as, in January 2014, he signed for Wolfsburg on a permanent basis.
Kevin hasn’t looked back since – he’s made 33 assists in 72 appearances for Wolfsburg in all competitions and he helped his nation to the World Cup quarter-finals in Brazil in 2014 where he netted one of the crucial goals to help the Red Devils past USA in the Second Round.
In all, De Bruyne has appeared for his country on 33 occasions, scoring eight goals.
He joins City with a reputation as one of the continent’s best playmakers, equally adept at playing on the wing or in behind the striker.
