Speaking to reporters, Priske said: "Yes I'm sure he is proud as an ex-Feyenoord manager, I know he is following us. We definitely did everything we could to help him as well.
"He had a massive impact on our club in the last three years and definitely gave me a good start with a good team and the Champions League competition. I'm happy we could maybe help him but he needs to do the dirty job at the weekend."
