AZ Alkmaar leads the implied probabilities for most clean sheets in the 2026-27 Eredivisie due to its early defensive metrics, including the fewest goals conceded and lowest shots faced per game after nine matches. Feyenoord’s recent streak of shutouts, driven by goalkeeper Tjark Ernst’s four clean sheets, keeps it competitive alongside Ajax despite the latter’s noted vulnerabilities to high-quality chances. PSV and Fortuna Sittard sit just behind in market pricing, reflecting solid but less dominant backlines. With the top contenders separated by narrow margins and roughly 25 rounds remaining, minor shifts in form, injuries, or schedule difficulty could readily alter the order.
