The Dutchman feels he is in the best form of his career.
He said: "I am not the king. Let's not exaggerate. But I am in great form thanks also to Inter, a club in which I find myself very well."
Asked if he feels this is the best moment of his career, the 25-year-old replied: "Certainly I feel very good. I am going through a wonderful period and I want to enjoy myself until the end. I too would like to win the Champions League as soon as possible. Even this year."
