Output in context · Castellón finished 2nd of 22 · a title-challenging side
3.44 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 9 appearances. Behind a title-challenging side (2nd 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
- Attacking threat. Chips in from deep: 0.22 goal involvements per 90, useful for a central defender.
Watch points
- Game time. Only 42.9% of available minutes — needs a settled run to prove the level.
Outlook
With a Rating of 53, Sienra carries the 22nd-highest potential of the centre-backs in the Segunda División of 47 — though on just 9 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (3.44 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.
