Shadrach Eghan scored twice as the Enschede club took full advantage of PSV Eindhoven's first defeat of the season at AZ Alkmaar on Saturday.

Feyenoord's rise up the table continued with a 4-2 win over ADO Den Haag in Rotterdam.

Higdon's goal came five minutes from the end but Piazon had the last word.
