James Dornelly is a 21-year-old full-back at Peterborough, rated 45.4 overall by Field Insider's model, ranking 102nd of 482 in the League One and 1401st of 2918 U-23 players tracked. A young player, he has been a rotation option this season (52.1% of available minutes). His defensive output reads 2.84 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Dornelly.
Judged on this season alone, Dornelly graded 16 — a workmanlike campaign that ranks 56th of 79 of the 79 full-backs in the League One, on 5 clean sheets and 2.835 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 7 → 16). Across the 3 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 45, top 17% of the 79 full-backs in the League One. At 21 Dornelly is still climbing toward his ceiling, and a market index of 9.1 reflects that trajectory.
A career still climbing — Dornelly is at his peak right now, and the curve hasn't flattened.
2.84 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 30 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 1 assist — a useful bonus from the back.
With a Rating of 45.4, Dornelly carries the 13th-highest potential of the full-backs in the League One (top 17%), and he is posting that for a lower-table side (Peterborough finished 18th of 24) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (2.84 tackles, blocks & interceptions per 90). At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output 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 (~10), then tapers with age. At 21, Dornelly sits on 9.1, still climbing toward its peak. The blue line is Dornelly's projected Rating — 45.4 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.
