**Early 2026-27 Eredivisie form highlights the vulnerability of several newly promoted sides and a couple of established clubs.** Cambuur, ADO Den Haag, Willem II, and Telstar occupy the bottom positions after the opening matchweeks, with Cambuur winless and conceding heavily while ADO and Utrecht sit on single points amid poor goal differences. These teams entered the season following promotion from the Eerste Divisie, bringing limited top-flight experience against a league dominated early by AZ, PSV, and Feyenoord. Recent results underscore defensive frailties and adaptation challenges for the promoted group, while mid-table sides like PEC Zwolle and Heerenveen have shown mixed starts. Schedule congestion, squad depth, and the typical relegation playoff battle (involving 16th place) will shape outcomes, with historical patterns favoring survival for clubs that stabilize quickly in the first 10-15 rounds.
