L. Donnelly is a 30-year-old full-back at ST Mirren, rated 20.5 overall by Field Insider's model, ranking 195th of 226 in the Premiership. An experienced operator, he has been a fringe squad member this season (24.5% of available minutes). His defensive output reads 4.92 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Donnelly.
Judged on this season alone, Donnelly graded 11 — a workmanlike campaign that ranks 35th of 41 of the 41 full-backs in the Premiership, on 2 clean sheets and 4.924 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 22 → 11). Over the 6 seasons on record his form has trended upward, peaking in 2022/23.
On long-term talent our Rating reads 21, 35th of 41 of the 41 full-backs in the Premiership. At 30 Donnelly is into the veteran stage, where the age curve weighs on the projection, and a market index of 2.3 reflects that trajectory.
Below his 2022/23 peak but holding a solid level — the platform for a return is there.
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.
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).
Generated from Field Insider's rating model · AI-written analysis to follow.
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.
