Sander van der Eijk, a 35-year-old referee, will lead Ajax-PSV on Saturday. This is his first top match in the Eredivisie. Van der Eijk has been active at the highest level since 2019. He has already refereed several matches this season, including Sparta Rotterdam – Feyenoord and Go Ahead Eagles – ADO Den Haag. The video arbitration for Ajax-PSV is in the hands of Pol van Boekel (VAR) and Dyon Fikkert (AVAR). AZ remains the only team faultless in the Eredivisie after four rounds, with Jeroen Manschot set to referee their match against SC Heerenveen on Sunday.
