AZ Alkmaar has secured contract extensions for two key players. Defender Wouter Goes signed a new deal extending his stay at the club until mid-2030. The 22-year-old, a product of the club’s youth academy, previously had a deal running until 2028. Despite expressing interest in a career step forward earlier this summer, Goes accepted the club’s decision to retain him, noting a preference for eventually moving to a club abroad rather than joining the top three teams in the Netherlands.

Following this, midfielder Peer Koopmeiners reached a verbal agreement for a one-year extension that will keep him at the club until mid-2029. This move follows AZ Alkmaar's refusal to sell the 26-year-old to Club Brugge despite high transfer bids, the highest of which reportedly reached approximately 13 million euros. Koopmeiners expressed satisfaction with the outcome, stating, “We are for both parties to something beautiful came,” even though he noted the disappointment of missing a potential opportunity to play in the Champions League with the Belgian champions. The extension for Koopmeiners will also include an improved salary.
