Dutch Eredivisie (the top tier of Dutch football) side PEC Zwolle claimed a surprise 2–0 victory at sc Heerenveen on Friday, with goals from Nick Viergever and Koen Kostons securing the club's first points of the season. Belgian winger Dylan Mbayo was the standout performer, providing the key assists for both goals after Zwolle weathered a dominant Heerenveen first half that included a Dylan Vente free kick rattling the crossbar. The defeat is Heerenveen's first of the season and denies them the chance to leapfrog rivals FC Groningen and close to within two points of league leaders AZ.
