Clean sheets

1.46 tackles, blocks & interceptions per 90 — light defensive volume, with 4 clean sheets across 32 appearances. Doing that for a lower-table side (15th of 18) 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 6 goals and 5 assists — a useful bonus from the back.

Strengths

Availability. On the pitch for 66.5% of available minutes — a dependable presence in the XI.
Attacking threat. Chips in from deep: 0.49 goal involvements per 90, useful for a central midfielder.

Watch points

Defensive numbers. Modest 1.46 defensive actions per 90 for the position.

Outlook

Rated 66.7 overall — a strong, regular top-tier starter. Defensively he reads as light defensive volume (1.46 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. Doing it for a lesser side, he profiles as a value buy for a club higher up the table.

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 age 25 (~35), then tapers with age. At 25, Rooij sits on 34.9, at or near its peak. The blue line is Rooij's projected Rating — 66.7 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.
