On long-term talent our Rating reads 37, 6th of 10 of the 10 attacking midfielders in the Segunda Liga. At 27 Gaag is in his prime years, and a market index of 25 reflects that trajectory.
A career still climbing — Gaag is at his peak right now, and the curve hasn't flattened.
2 goals in 22 appearances (0.09 per game) — light end product the role wants to see climb. Add 1 assist for 3 goal contributions in all.
With a Rating of 36.8, Gaag carries the 6th-highest potential of the attacking midfielders in the Segunda Liga of 10 — though on just 22 appearances this season, so the standing rests on a small sample. In the final third he profiles as a productive contributor (0.37 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 (~25), then tapers with age. At 27, Gaag sits on 25, at or near its peak. The blue line is Gaag's projected Rating — 36.8 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.
