Among the reinforcements who joined Barça Athletic in the winter transfer window, 18-year-old Dutch centre-back Jewensley Onssein stands out as the only signing for whom the club made a direct financial investment. That decision reflects the sporting management, led by Deco, valuing his profile as a strong fit for Barcelona’s defensive needs.
Standing at almost 1.90 metres, he is a left-footed defender known for his pace, physical power and one-on-one strength. However, he arrives after a lengthy spell without match action, having not played since October, so the club has put in place a structured roadmap to rebuild his competitive rhythm gradually.
He started with individual training sessions and then joined reserve-team practices under Juliano Belletti. The next step in his development has been confirmed: he has been included in Pol Planas’ Juvenil A squad for the game against Sant Cugat at the Ciutat Esportiva Joan Gamper, where he is expected to see his first minutes.
The technical staff will make the final call on his participation depending on how the match unfolds, and Flick will be closely monitoring his progress. The club also notes that his background at Ajax should help him adapt quickly to Barcelona’s distinctive playing philosophy.
Before moving to Barcelona he had been with Genk, and the club views him as a long-term prospect who could be ready for Barça Athletic within a couple of weeks. For now, today's youth fixture represents the essential first step in integrating his powerful defensive profile into the Blaugrana ecosystem.
