Output in context · Castellón finished 6th of 22 · an upper-table side
3.79 tackles, blocks & interceptions per 90 — solid defensive volume, with 5 clean sheets across 26 appearances. Behind an upper-table side (6th of 22) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 2 goals and 0 assists — a useful bonus from the back.
Strengths
- Defensive volume. 3.79 tackles, blocks & interceptions per 90 — does the unseen work.
Watch points
- Game time. Only 44.9% of available minutes — needs a settled run to prove the level.
Outlook
Rated 49.2 overall — a solid contributor and squad regular. Defensively he reads as solid defensive volume (3.79 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
