On long-term talent our Rating reads 58. At 24 Sarmiento is in his prime years, and a market index of 73.6 reflects that trajectory.
Read the appearance count in context: Sarmiento missed 4 games through injury (inactive, lacking match fitness, thigh) out of roughly 49 this season. The 20 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
Past his 2024/25 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
1.85 tackles, blocks & interceptions per 90 — light defensive volume, with 2 clean sheets across 20 appearances. Behind an upper-table side (5th of 24) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume.
Rated 57.5 overall — a solid contributor and squad regular. Defensively he reads as light defensive volume (1.85 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

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 (~74), then tapers with age. At 24, Sarmiento sits on 73.6, at or near its peak. The blue line is Sarmiento's projected Rating — 57.5 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.
