Clean sheets

3.42 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 19 appearances. Doing that for a lower-table side (15th 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. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.

Outlook

Rated 13.2 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.42 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× and falling).

Market valueRating

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 (~8), then tapers with age. At 36, Martin sits on 2.5, past its peak and easing. The blue line is Martin's projected Rating — 13.2 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.
