On long-term talent our Rating reads 30. At 27 Duin is in his prime years, and a market index of 5.6 reflects that trajectory.
Read the appearance count in context: Duin missed 17 games through injury (injury, jumpers knee, knee) out of roughly 32 this season. The 6 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 2020/21 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
1 goal in 6 appearances (0.17 per game) — light end product the role wants to see climb.
Rated 29.8 overall — below regular-starter level. In the final third he profiles as a productive contributor (0.43 goal contributions 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 (~6), then tapers with age. At 27, Duin sits on 5.6, at or near its peak. The blue line is Duin's projected Rating — 29.8 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.
