The Belgium midfielder has long been linked with a £40million move to Manchester City.
Hecking has revealed that City face competition from Barcelona, Real Madrid and Bayern Munich in their move to sign the 24-year-old midfielder.
Hecking told Spox.com: “Despite my esteem for Manchester City, I have to say that Real Madrid, Bayern Munich and Barcelona have all expressed an interest in Kevin de Bruyne and there have been approaches for him.
“He will only leave if there is an extraordinary offer for him. I am not ruling anything out and we will listen to offers, but in reality we could allow him to leave for a huge offer.”
