Clean sheets

3.47 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 15 appearances. Doing that for a relegation-threatened side (11th of 12) 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. Going forward he chipped in 1 goal and 1 assist — a useful bonus from the back.

Outlook

With a Rating of 36.6, Olesen carries the 30th-highest potential of the defensive midfielders in the Bundesliga of 47, and he is posting that for a relegation-threatened side (Grazer AK finished 11th of 12) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (3.47 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

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 (~7), then tapers with age. At 25, Olesen sits on 7.1, at or near its peak. The blue line is Olesen's projected Rating — 36.6 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.
