Dies Janse, a 20-year-old Dutch Centre-Back, is among 21 players that Ajax has placed on the online transfer platform TransferRoom. Being placed on the list does not necessarily mean all 21 players must leave the club. For some, departure is desirable, while for others it is a way to attract additional attention on the market. Janse spent the 2025/2026 season on loan at FC Groningen, making 31 appearances in the Eredivisie, scoring 2 goals and providing 2 assists. The defender, who has two caps for the Netherlands U21 team, has a contract with Ajax until June 30, 2029. His current Transfermarkt market value is €6.50m and he has been linked with Club Brugge.
