In the final third he profiles as a work-in-progress on end product (0 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 (~15), then tapers with age. At 27, Þorsteinsson sits on 15.3, at or near its peak. The blue line is Þorsteinsson's projected Rating — 40.1 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines.
