The 18-year-old has appeared in every Eredivisie game so far this campaign after making his debut last season, and is now a key player for the club featuring in either a central or attacking midfield role.
His importance to AZ is reflected in his contract which runs until June 2015, and as the club do not need to sell players going into the transfer window, he will not be allowed to leave cheaply.
The report claims he has already turned down an offer from Manchester City, and in any case the youngster would struggle for game time at either Premier League side. He may, therefore, be set to stay with his first club for a while as he hopes to continue his progress.
Alkmaar appear to have much to offer him in the near future, sitting top of the Eredivisie halfway through the season and still in the Europa League.
