Clean sheets

2.95 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 23 appearances. Doing that for a lower-table side (17th of 20) 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 4 goals and 8 assists — a useful bonus from the back.

Strengths

Attacking threat. Chips in from deep: 0.58 goal involvements per 90, useful for a defensive midfielder.
Creativity. 0.39 assists per 90 — a genuine creative outlet.
Ceiling. High potential at just 20 — room to grow into a bigger role.

Watch points

Game time. Only 54.4% of available minutes — needs a settled run to prove the level.

Outlook

Rated 55.3 overall — a solid contributor and squad regular. Defensively he reads as moderate defensive volume (2.95 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output follow. With this floor already at 20, the ceiling gets tested by a step up in level — one to track.

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 (~32), then tapers with age. At 20, Boogaard sits on 17.2, still climbing toward its peak. The blue line is Boogaard's projected Rating — 55.3 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.
