Clean sheets

2.63 tackles, blocks & interceptions per 90 — moderate defensive volume, with 13 clean sheets across 32 appearances. Behind a title-challenging side (2nd of 17) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 1 goal and 4 assists — a useful bonus from the back.

Strengths

Availability. On the pitch for 90.6% of available minutes — a dependable presence in the XI.
Attacking threat. Chips in from deep: 0.16 goal involvements per 90, useful for a defensive midfielder.

Watch points

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

Outlook

Rated 44 overall — developing / rotation level. Defensively he reads as moderate defensive volume (2.63 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around age 27 (~13), then tapers with age. At 27, Kairinen sits on 13.1, at or near its peak. The blue line is Kairinen's projected Rating — 44 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.
