Voetbalprimeur.nl reported that Matej Sin will leave AZ for ADO Den Haag on loan for the coming season. AZ announced the move through its official channels. The loan does not include a purchase option, and Sin will return to AZ after the loan period. According to the club, the loan will give Sin more chances for playing minutes in the Eredivisie.

ADO Den Haag will loan 22-year-old midfielder Matej Sin from AZ for one year, pending a medical examination to finalize the agreement. AZ acquired Sin from Banik Ostrava in the middle of the previous year for a fee reported to be four million euros, but he did not become a key player. The midfielder, who can also play on the wing, has a contract with AZ that is valid until the summer of 2030.
