Willems said he was not impressed by the slap. “I am fortunately from Rotterdam-Zuid, so I did experience something. I didn’t feel threatened,” he told NOS Sport.
Managing director Wouter Gudde condemned the out-of-control situation. “A brainless imbecile” he called the person who had attacked Willems. “We will sit down with Jetro on Monday morning regarding a possible report. I have a clear opinion on that myself.”
