19 clean sheets in 38 appearances (50% of games). Playing behind a title-challenging side (2nd of 20) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.

Strengths

Availability. On the pitch for 100% of available minutes — a dependable presence in the XI.

Watch points

Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 41.5 overall — developing / rotation level. A near ever-present keeper carrying the gloves this season. Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).

Market valueRating

Solid = now · dashed = projected

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 (~19), then tapers with age. At 29, Kojima sits on 10.4, past its peak and easing. The blue line is Kojima's projected Rating — 41.5 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.
