Clubs are queuing to take Kevin De Bruyne on-loan from Chelsea next season.
De Bruyne, currently on-loan at RacingGenk, will do preseason with Chelsea before a decision is made over whether he stays or spends the season away.
Lille, FC Twente, Hoffenheim and VfL Wolfsburg are all being linked with the winger.
Patrick De Koster said: "There's been lately a lot of things in the newspapers, but these are just rumours. Currently there is no contact."
