B. Nieuwkoop is a 30-year-old central defender at Feyenoord, rated 32.9 overall by Field Insider's model.

Below: strengths, watch-points, market-value outlook and the latest transfer news on Nieuwkoop.
On the season, Nieuwkoop graded 17 for current form (age-blind), on 2 clean sheets and 4.856 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 11 → 17). Over the 6 seasons on record his form has drifted down, peaking in 2021/22.
On long-term talent our Rating reads 33. At 30 Nieuwkoop is into the veteran stage, where the age curve weighs on the projection, and a market index of 21.1 reflects that trajectory.
Read the appearance count in context: Nieuwkoop missed 10 games through injury (injury, leg, groin) out of roughly 34 this season. The 17 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
Past his 2021/22 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
4.86 tackles, blocks & interceptions per 90 — solid defensive volume, with 2 clean sheets across 17 appearances. Behind a title-challenging side (2nd 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 1 goal and 0 assists — a useful bonus from the back.
Rated 32.9 overall — below regular-starter level. Defensively he reads as solid defensive volume (4.86 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).

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 (~42), then tapers with age. At 30, Nieuwkoop sits on 21.1, past its peak and easing. The blue line is Nieuwkoop's projected Rating — 32.9 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.
