Clean sheets

3.13 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 26 appearances. Doing that for a lower-table side (13th of 18) 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 65.8% of available minutes — a dependable presence in the XI.

Outlook

Rated 29.9 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.13 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).

Solid = now · dashed = projected

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 (~19), then tapers with age. At 30, Sierro sits on 4.4, past its peak and easing. The blue line is Sierro's projected Rating — 29.9 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.
