Clean sheets

3.1 tackles, blocks & interceptions per 90 — moderate defensive volume, with 1 clean sheet across 7 appearances. Doing that for a relegation-threatened side (13th of 14) 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.

Outlook

Rated 21.6 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.1 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× 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 (~3), then tapers with age. At 28, Guillaumier sits on 2.1, past its peak and easing. The blue line is Guillaumier's projected Rating — 21.6 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.
