Below: strengths, watch-points, market-value outlook and the latest transfer news on Ishii.
Judged on this season alone, Ishii graded 5 — a workmanlike campaign that ranks 51st of 61 of the 61 centre-backs in the J3 League, on 2 clean sheets and 1.921 defensive actions per 90.
We hold a single season for Ishii, so there's no year-on-year comparison to draw yet — the read above is this campaign only.
On long-term talent our Rating reads 10, 53rd of 61 of the 61 centre-backs in the J3 League. At 31 Ishii is into the veteran stage, where the age curve weighs on the projection, and a market index of 0.4 reflects that trajectory.
Output in context · Parceiro Nagano finished 19th of 20 · a relegation-threatened side
1.92 tackles, blocks & interceptions per 90 — light defensive volume, with 2 clean sheets across 8 appearances. Doing that for a relegation-threatened side (19th of 20) 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.
Watch points
- Game time. Only 19.2% 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 10.2, Ishii carries the 53rd-highest potential of the centre-backs in the J3 League of 61 — though on just 8 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (1.92 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
