The Blues star man has been linked with a summer move to the Bernabeu with the Los Blancos said to be willing to pay as much as £100million to get him.
But the Belgian is continuing to keep his cards close to his chest and insists he remains happy in London.
“There is nothing to say,” he said when asked for an update on his future. “I take it game by game. I try to play as much as possible. That's it.”
Pressed further, he added: “Why do you want to put me in s***? No, I'm very well here. I have stuff to finish this year.
“I have a contract until 2020. Voila, for now I'm here.”
