The Belgium international, who signed for the Blues in 2012, is currently on a season-long loan at Werder Bremen.
The 21-year-old is in fine form at the Bundesliga side and rumours have suggested that a permanent move could be a possibility. De Bruyne has also revealed that he does not know whether Chelsea want him at the club next season.
When asked if he will be with the Premier League side next season, De Bruyne told Belgian daily Derniere Heure: "I'll make a confession: I do not think so.
"In Bremen, I do not even talk of Chelsea. What I am interested in at the moment is picking up more points with Werder.
"Recently, a Chelsea scout came to see me play against Hamburg, talked to me for five minutes after the game, with the message 'well, your progress continues.'"
De Bruyne's current deal with Chelsea runs until 2017.
