Scout report

Squad depthFull-back

Dion-Johan Cools is a 30-year-old full-back at Cerezo Osaka, rated 24.2 overall by Field Insider's model, ranking 268th of 377 on scout potential in the J1 League. An experienced operator, he has been a fringe squad member this season (27% of available minutes). His defensive output reads 4 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Cools.

Judged on this season alone, Cools graded 8 — a workmanlike campaign that ranks 51st of 54 of the 54 full-backs in the J1 League, on 1 clean sheet and 3.998 defensive actions per 90.

Year-on-year, that's broadly in line with last season (Season 10 → 8). Over the 3 seasons on record his form has drifted down, peaking in 2020/21.

On long-term talent our Rating reads 24, 38th of 54 of the 54 full-backs in the J1 League. At 30 Cools is into the veteran stage, where the age curve weighs on the projection, and a market index of 3.3 reflects that trajectory.

Clean sheets

4 tackles, blocks & interceptions per 90 — solid defensive volume, with 1 clean sheet across 14 appearances. Going forward he chipped in 2 goals and 1 assist — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.29 goal involvements per 90, useful for a full-back.
  • Defensive volume. 4 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Game time. Only 27% of available minutes — needs a settled run to prove the level.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 24.2, Cools carries the 38th-highest potential of the full-backs in the J1 League of 54 — though on just 14 appearances this season, so the standing rests on a small sample. Defensively he reads as solid defensive volume (4 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).
