Scout report
J. Cooper is a 31-year-old full-back at Millwall, rated 30.2 overall by Field Insider's model, ranking 192nd of 272 on scout potential in the Championship. A seasoned veteran, he has been a rotation option this season (47.4% of available minutes). His defensive output reads 3.48 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Cooper.
Judged on this season alone, Cooper graded 29 — a strong campaign that ranks top 28% of the 37 full-backs in the Championship, on 4 clean sheets and 3.483 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 53 → 29). Over the 7 seasons on record his form has drifted down, peaking in 2020/21.
On long-term talent our Rating reads 30, 31st of 37 of the 37 full-backs in the Championship. At 31 Cooper is into the veteran stage, where the age curve weighs on the projection, and a market index of 10 reflects that trajectory.
Past his 2020/21 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
Output in context · Millwall finished 12th of 24 · a mid-table side
3.48 tackles, blocks & interceptions per 90 — moderate defensive volume, with 4 clean sheets across 11 appearances. Going forward he chipped in 1 goal and 1 assist — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.18 goal involvements per 90, useful for a full-back.
Watch points
- Game time. Only 47.4% of available minutes — needs a settled run to prove the level.
- Age curve. At 31, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 30.2, Cooper carries the 31st-highest potential of the full-backs in the Championship of 37 — though on just 11 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (3.48 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
