Output in context · Newells Old Boys finished 14th of 15 · a relegation-threatened side
3.54 tackles, blocks & interceptions per 90 — solid defensive volume, with 3 clean sheets across 24 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 1 goal and 1 assist — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.16 goal involvements per 90, useful for a defensive midfielder.
- Defensive volume. 3.54 tackles, blocks & interceptions per 90 — does the unseen work.
Watch points
- Game time. Only 42.8% of available minutes — needs a settled run to prove the level.
Outlook
With a Rating of 48.3, Mattar carries the 18th-highest potential of the defensive midfielders in the Liga Profesional Argentina (top 25%), 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 solid defensive volume (3.54 tackles, blocks & interceptions per 90). At 18 the trajectory points up — potential sits near its ceiling (100/100) and market value should climb as minutes and output follow. With this floor already at 18, the ceiling gets tested by a step up in level — one to track.
