Sydney Osazuwa has completed a loan move from Real Sociedad B to AZ Alkmaar U21, leaving Spain to join the Dutch club’s second team in the Keuken Kampioen Divisie. The 18‑year‑old centre‑forward joins AZ’s U21 setup on a temporary deal, officially moving on 2026-02-02, with his contract at the Dutch side running until 2026-06-30, when he is scheduled to return to Real Sociedad B at the end of the loan.
The transfer is registered as a loan transfer, with no permanent fee involved, and comes at a time when Osazuwa’s market value is listed at €1.00m. The switch takes him from LaLiga2, where Real Sociedad B compete, to the Netherlands’ second tier, offering the tall forward a first confirmed spell abroad after spending his entire development in Spanish football.
Osazuwa arrives at AZ Alkmaar U21 as a right‑footed centre-forward, standing 1.93m, and is expected to add physical presence and depth to the Dutch club’s attacking options. Born in Fuenlabrada and holding both Spanish and Nigerian nationality, he will now continue his progression in a new footballing culture, while remaining tied contractually to the Basque club, who retain his rights beyond the end of the loan.
Before this move, Osazuwa’s career path had kept him firmly within Spain’s youth and reserve structures. He came through Atlético Madrid’s youth ranks before spells with CD Móstoles URJC U19, Getafe CF Youth and Granada CF Youth. From Granada he moved to CD Leganés U19, and then stepped into the professional reserve game with Real Sociedad B. That trajectory has now taken another step with his confirmed move to AZ’s U21 side in the Dutch system.
The loan also has implications for his medium‑term status. With the deal explicitly set to end on 2026-06-30, there is a clear decision point ahead: Real Sociedad B will need to determine whether to reintegrate him, extend his deal, arrange another move or risk him moving closer to free‑agent territory in future if no new agreement is reached beyond his parent‑club contract horizon, which is not specified in the current data.
Osazuwa’s previous market value history shows that he was valued as high as €2.00m during his time at Real Sociedad B before that figure settled at €1.00m by the time of this transfer. That fluctuation underscores both his perceived potential and the importance of regular competitive minutes in a demanding league such as the Keuken Kampioen Divisie, where he is likely to face a different style of football to LaLiga2.
The move also highlights his status with AZ Alkmaar’s structure, as he is listed with AZ Alkmaar U21 as his current club and national team designation, underlining how central this developmental phase is to his career. With his size, dual nationality and experience across several respected Spanish academies, his performance in the Netherlands will be closely monitored by both Spanish and Nigerian observers who see him as a prospect for the future.
As Osazuwa settles in at AZ Alkmaar U21 under this confirmed loan, the coming months in Dutch football will be crucial in determining whether he returns to San Sebastián as a more complete forward, earns a longer‑term future in the Netherlands, or moves along a different path altogether once his loan contract ends on 2026-06-30.
