N. Martens is a 22-year-old full-back at De Graafschap, rated 52 overall by Field Insider's model, ranking 167th of 376 in the Eerste Divisie and 1016th of 2819 U-23 players tracked. An emerging talent, he has been a fringe squad member this season (29.1% of available minutes). His defensive output reads 2.66 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Martens.
Judged on this season alone, Martens graded 8 — a workmanlike campaign that ranks 75th of 81 of the 81 full-backs in the Eerste Divisie, on 2 clean sheets and 2.66 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 5 → 8). Over the 4 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 52, 36th of 81 of the 81 full-backs in the Eerste Divisie. At 22 Martens is still climbing toward his ceiling, and a market index of 40.5 reflects that trajectory.
Below his 2022/23 peak but holding a solid level — the platform for a return is there.
2.66 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 14 appearances. Behind an upper-table side (4th of 20) 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 2 assists — a useful bonus from the back.
With a Rating of 52, Martens carries the 36th-highest potential of the full-backs in the Eerste Divisie of 81 — though on just 14 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.66 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 1.9×) with the best seasons likely ahead. With this floor already at 22, the ceiling gets tested by a step up in level — one to track.
Generated from Field Insider's rating model · AI-written analysis to follow.
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 (~43), then tapers with age. At 22, Martens sits on 40.5, still climbing toward its peak. The blue line is Martens's projected Rating — 52 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.
