European football leagues begin new seasons with format and roster changes

Major European football leagues, including the Dutch Eredivisie and the Belgian Jupiler Pro League, are beginning their new seasons, bringing various developments across the clubs.

In the Netherlands, Ajax is preparing for their Eredivisie debut with a squad undergoing adjustments, while PEC Zwolle's goalkeeper trainer Diederik Boer anticipates a challenge against his former club. Other Dutch updates include ADO Den Haag's return to the top flight and the competitive landscape of the Keuken Kampioen Divisie.

In Belgium, the Jupiler Pro League has implemented a significant format change, moving from 16 to 18 teams and eliminating playoffs. This expansion has led to an increase in season subscription costs, which have risen by more than 25% over the last decade. Analysts have named Club Brugge and Union as title favorites, though concerns remain regarding player fatigue due to short off-seasons.
