The Toffees’ director of football Marcel Brands is said to be a big fan of Koopmeiners, who has been an important part of the team who were giving Ajax a run for their money in the Dutch league this season.
AZ Alkmaar were level on points with Ajax at the top before the Eredivisie was scrapped, only behind on goal difference.

The 22-year-old has also been a permanent fixture in the Netherlands Under-21 team.
He played 42 games for AZ Alkmaar this season, scoring 16 goals and providing three assists.
Everton midfielders Morgan Schneiderlin and Gylfi Sigurdsson are now both 30-years-old, and the club will be looking for long-term replacements.
Everton aren’t the only team interested in his signature, with AC Milan also thought to be in the hunt.

The move could be funded by the departure of Moise Kean, with Inter Milan preparing a £25million bid for the striker who has not had an enjoyable time in the Premier League since his arrival.
The Dutch league was ended prematurely due to the coronavirus, and teams have qualified for European competitions based on their standings, which has caused fury among certain clubs.
AZ Alkmaar will be entering the Champions League at a different stage than Ajax despite being level on points, and FC Utrecht have missed out on a Europa League spot despite having a game in hand over the team three points above them.
