Willem van Hanegem, a well-known figure in Dutch football, has noticed a change in the way young players are developing at AZ. In the past, the best young talent often made the move to Ajax, but it seems that AZ is now a more attractive destination for many of these players. Van Hanegem attributes this to the club's ability to retain its young talent, suggesting that AZ is now a preferred choice for many young players. This is a significant development in the Dutch football landscape, and one that is worth keeping an eye on.
