Van Duijn returned to AZ this summer after spending the second half of the previous season on loan at Telstar, where he impressed under Correia and played a key role in the team's fight for league survival. During his time at Telstar, Van Duijn scored five goals in the Eredivisie. He signed a new contract with AZ until mid-2031, but now stands on the verge of another temporary departure from Alkmaar. Van Duijn had the chance to prove himself in the first team during the pre-season, but is now set to join FC Utrecht, a known entity in the Eredivisie. Correia, who worked with Van Duijn at Telstar, will be a familiar face for the attacker in Utrecht.
