De Bruyne has had a glittering spell since joining the club from Wolfsburg in 2015, winning seven major trophies, which could become 11 by the end of the season if City are successful in their hunt for a quadruple.
However, ominously for the rest of Europe, he reckons the best is yet to come for himself and Pep Guardiola's team.
"I could not be happier. Since joining City in 2015, I have felt at home," he said. "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."
