The highly-rated youngster signed at Stamford Bridge on a five-and-a-half year deal from Genk in January before spending the remainder of last season on loan at the Belgian club.
De Bruyne, who is yet to make his competitive debut for Chelsea, then joined Werder Bremen on a season-long loan in August after partaking in the Blues' pre-season tour.
The 21-year-old has established himself as a first-team regular at the Bundesliga club and his agent, Patrick de Koster, claims general manager Klaus Allofs is a big admirer of the winger.
But De Koster says De Bruyne, who has scored four goals in 17 appearances for Bremen, sees his long-term future at Chelsea and there have been no talks over him making his stay in Germany permanent.
The agent told Wolfsburger Nachrichten: "Kevin de Bruyne is on loan at Werder Bremen. The fact is that he will return to Chelsea at the end of the campaign.
"He has a contract going on at Stamford Bridge."
De Koster added: "It's great to know that Kevin de Bruyne is of interest to many clubs in the top leagues and I know that Klaus Allofs is a fan of him. We are definitely aware of that. But up to now we have not been discussing a transfer."
