Clean sheets

4.92 tackles, blocks & interceptions per 90 — solid defensive volume, with 2 clean sheets across 17 appearances. Doing that for a relegation-threatened side (10th of 12) 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 1 goal and 0 assists — a useful bonus from the back.

Outlook

With a Rating of 20.5, Donnelly carries the 35th-highest potential of the full-backs in the Premiership of 41 — though on just 17 appearances this season, so the standing rests on a small sample. Defensively he reads as solid defensive volume (4.92 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 (~5), then tapers with age. At 30, Donnelly sits on 2.3, past its peak and easing. The blue line is Donnelly's projected Rating — 20.5 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.
