The reigning Professional Footballers Association (PFA) Player of the year joined Manchester City from German Bundesliga side Wolfsburg in the summer of 2015 for a then club-record fee of £55m and has enjoyed enormous success at the Etihad Stadium.
De Bruyne has won two league titles, four League Cups and one FA Cup with the Citizens, and with Pep Guardiola’s men still in the hunt for a famous quadruple this season, he could add to his trophy collection by the end of the campaign.
"I could not be happier, since joining City in 2015, I have felt at home," De Bruyne said after his contract was confirmed. "I love the fans, my family are settled here in Manchester and my own game has developed really well.
"This football club is geared for success. It offers me everything I need to maximise my performance, so signing this contract was a straightforward decision. I am playing the best football of my career and I honestly feel there is more to come.
"Pep and I see football in the same way. Having that relationship with a manager is so important to me because our objectives are totally aligned, and we want the same things.
"My focus now is on ensuring we have a successful end to the current campaign. Our results and performances so far have been excellent, but we need to make sure we end the season with the silverware we deserve."
The Belgium international has made 33 appearances, contributed 16 assists and scored eight goals in all competitions for Manchester City this season.
