He told Voetbalzone, "I came into contact with Chelsea through my agent. Then the ball started to roll: having conversations, making analysis, talking to people and persuading them. It is a huge step.
"From Go Ahead to Twente was a step. But from Twente to Chelsea and the requirements that this function entails is a much larger step. The way in which Chelsea organised the scouting is of course a lot more professional than with FC Twente. That makes sense, because you can not compare those clubs at all.
"This job at Chelsea is a confirmation that you have done things right. There are more clubs that approached me and also came up with more attractive conditions."
