On long-term talent our Rating reads 33. At 27 Mattsson is in his prime years, and a market index of 17.3 reflects that trajectory.
Read the appearance count in context: Mattsson missed 27 games through injury (knee) out of roughly 33 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 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
2 goals in 6 appearances (0.33 per game) — light end product the role wants to see climb. Add 1 assist for 3 goal contributions in all.
Rated 33.2 overall — below regular-starter level. In the final third he profiles as a genuine goal threat (0.59 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.

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 (~17), then tapers with age. At 27, Mattsson sits on 17.3, at or near its peak. The blue line is Mattsson's projected Rating — 33.2 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.
