The Dutchman has been in exciting form in preseason and declared: "I hope this is my year, but when you think about it, it becomes more difficult. Now I feel good and I am very keen.
"This season I want to enjoy playing soccer and not worry about injuries. My first objective is to be important for this team.
"It hurts a little when people say I'm injury-prone. I am not made of glass, it is only a consequence of a back problem. When people see me train they do not say these things because I show that I can be very strong."
