Few people have a better view on Dutch top talents than he has, and I imagine he personally knows most youth coaches at the bigger clubs. Also worked at Feyenoord for more than 10 years, so that also helps in this case. Feyenoord has had the best academy in Holland for a couple of years now, and Tahith Chong was the only talent of his team that was fasttracked this summer from the under 15 team to the under 17 team, skipping the under 16 team.
Have to say as a Dutchie I don't like our players leaving as such a young age, don't think it's good for Dutch youth development. But what can you do.
