The KNVB has appointed arbitrator Serdar Gözübüyük on Tuesday for the Eredivisie top match between league-leader Ajax and number two AZ on Sunday. PSV-Feyenoord in Eindhoven is led earlier in the day by Dennis Higler.

For 34-year-old Gözübüyük, who receives assistance from VAR Clay Ruperti, it will be his second topper of the season. At the end of October he was already in charge of the Classic between Ajax and Feyenoord in the Johan Cruijff ArenA.

The 34-year old Higler was not yet active in a topper this season. The referee from Amersfoort receives help from Rob Dieperink in the Philips Stadium, who acts as a VAR.

The difference on the ranking between Ajax and AZ is three points. Four points behind the Alkmaarders is Feyenoord, which has a point margin compared to PSV. Ajax-AZ starts on Sunday at 8 p.m. and the kick-off of PSV-Feyenoord is at 2.30 p.m.

Higler has been designated as a VAR for the competition in Utrecht's Galgenwaard. Pol van Boekel provides assistance from Zeist in the second semifinal.
