Clean sheets

3.04 tackles, blocks & interceptions per 90 — moderate defensive volume, with 18 clean sheets across 40 appearances. Behind an upper-table side (7th 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 1 assist — a useful bonus from the back.

Strengths

  • Availability. On the pitch for 94.8% of available minutes — a dependable presence in the XI.

Watch points

  • Age curve. At 33, both level and resale value are on the downslope.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 29.6, Grego carries the 59th-highest potential of the centre-backs in the Segunda División of 79. Defensively he reads as moderate defensive volume (3.04 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).
