Clean sheets

3.37 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 19 appearances. Doing that for a lower-table side (18th of 24) 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 2 goals and 0 assists — a useful bonus from the back.

Strengths

Attacking threat. Chips in from deep: 0.16 goal involvements per 90, useful for a central defender.

Watch points

Game time. Only 27.7% of available minutes — needs a settled run to prove the level.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 31 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.37 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).

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 (~14), then tapers with age. At 30, Shaughnessy sits on 7.1, past its peak and easing. The blue line is Shaughnessy's projected Rating — 31 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.
