Judged on this season alone, Grego graded 20 — a workmanlike campaign that ranks 30th of 47 of the 47 centre-backs in the Segunda División, on 3 clean sheets and 2.584 defensive actions per 90.

Year-on-year, that's a drop on last season (Season 62 → 20). Over the 7 seasons on record his form has drifted down, peaking in 2025/26.

On long-term talent our Rating reads 19, 33rd of 47 of the 47 centre-backs in the Segunda División. At 33 Grego is into the veteran stage, where the age curve weighs on the projection, and a market index of 4.8 reflects that trajectory.

2.58 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 9 appearances.

Watch points

  • Game time. Only 42.4% of available minutes — needs a settled run to prove the level.
  • 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 19.3, Grego carries the 33rd-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 (2.58 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).
