Judged on this season alone, Ienaga graded 14 — a workmanlike campaign that ranks 10th of 24 of the 24 central midfielders in the J1 League, on 1 goal, 1 assist and 1.815 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 35 → 14). Over the 6 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 8, 23rd of 24 of the 24 central midfielders in the J1 League. At 40 Ienaga is into the veteran stage, where the age curve weighs on the projection, and a market index of 0.9 reflects that trajectory.
Past his 2022/23 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
