"Cardiff City have incredible fans," said the Dutchman.
"I watched them at Ninian Park a couple of times when I went to visit my old mate Glenn Loovens last season.
"He would always tell me tales about their fans - and then I witnessed it for myself. They are passionate, they are outstanding in their support.
"The atmosphere will be similar to that at Stoke City's Britannia Stadium - and we lost [2-1 in the Premier League] there.
"It is going to be tough. I would be far happier if we had been at home, but if we match their work-rate I am positive we can come out on top."
