De Bruyne has scored three goals and laid another six on for his teammates this season.
And his performances have not gone unnoticed on the continent.
Don Balon says Real Madrid are interested in his services and are prepared to make a huge bid in January.
A bid of £88.6m (€100m) is being readied by the Spanish club, and they remain confident as long as the ex-Wolfsburg midfielder has not put pen to paper on a new deal at the Etihad.
The 26-year-old signed a six-year deal when he joined in 2015 and recently hinted he is ready to extend his stay at City.
