Output in context · Newells Old Boys finished 14th of 15 · a relegation-threatened side
3.32 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 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 0 goals and 1 assist — a useful bonus from the back.
Watch points
- Game time. Only 43.3% of available minutes — needs a settled run to prove the level.
Outlook
With a Rating of 47.8, Mattar carries the 25th-highest potential of the central midfielders in the Liga Profesional Argentina (top 27%), 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 (3.32 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.
