Clean sheets

3.65 tackles, blocks & interceptions per 90 — solid defensive volume, with 7 clean sheets across 24 appearances. Behind an upper-table side (6th of 18) 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 0 goals and 1 assist — a useful bonus from the back.

Strengths

Defensive volume. 3.65 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Game time. Only 45.9% of available minutes — needs a settled run to prove the level.

Outlook

Rated 57.1 overall — a solid contributor and squad regular. Defensively he reads as solid defensive volume (3.65 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

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 (~22), then tapers with age. At 24, Sekine sits on 21.4, at or near its peak. The blue line is Sekine's projected Rating — 57.1 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.
