Clean sheets

2.44 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 20 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. Going forward he chipped in 2 goals and 1 assist — a useful bonus from the back.

Strengths

Availability. On the pitch for 82% of available minutes — a dependable presence in the XI.
Attacking threat. Chips in from deep: 0.26 goal involvements per 90, useful for a central midfielder.

Watch points

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

Outlook

With a Rating of 35, Mazzantti carries the 59th-highest potential of the central midfielders in the Liga Profesional Argentina of 96, 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 moderate defensive volume (2.44 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~16), then tapers with age. At 29, Mazzantti sits on 8.5, past its peak and easing. The blue line is Mazzantti's projected Rating — 35 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
