Clean sheets

5.24 tackles, blocks & interceptions per 90 — high defensive volume, with 7 clean sheets across 28 appearances. Doing that for a relegation-threatened side (14th of 15) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight.

Strengths

  • Availability. On the pitch for 93.4% of available minutes — a dependable presence in the XI.
  • Defensive volume. 5.24 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 39.3, Montero carries the 36th-highest potential of the defensive midfielders in the Liga Profesional Argentina of 64, and he is posting that for a relegation-threatened side (Newells Old Boys finished 14th of 15) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as high defensive volume (5.24 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).
