N. Koulis is a 27-year-old central defender at Preußen Münster, rated 39.9 overall by Field Insider's model, ranking 236th of 320 in the 2. Bundesliga. In his prime years, he has been a fringe squad member this season (30.3% of available minutes). His defensive output reads 3.01 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Koulis.
Judged on this season alone, Koulis graded 7 — a workmanlike campaign that ranks 56th of 57 of the 57 centre-backs in the 2. Bundesliga, on 1 clean sheet and 3.01 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 33 → 7). Over the 4 seasons on record his form has trended upward, peaking in 2024/25.
On long-term talent our Rating reads 40, 39th of 57 of the 57 centre-backs in the 2. Bundesliga. At 27 Koulis is in his prime years, and a market index of 42.3 reflects that trajectory.
Past his 2024/25 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
3.01 tackles, blocks & interceptions per 90 — moderate defensive volume, with 1 clean sheet across 16 appearances. Doing that for a relegation-threatened side (18th 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.
With a Rating of 39.9, Koulis carries the 39th-highest potential of the centre-backs in the 2. Bundesliga of 57, and he is posting that for a relegation-threatened side (Preußen Münster finished 18th of 18) — 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 (3.01 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
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 (~42), then tapers with age. At 27, Koulis sits on 42.3, at or near its peak. The blue line is Koulis's projected Rating — 39.9 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.
