Watch points

Game time. Only 23% of available minutes — needs a settled run to prove the level.
Output. 0.13 contributions per 90 is light for an attacking role — end product needs to climb.

Outlook

Rated 68.5 overall — a strong, regular top-tier starter. In the final third he profiles as a work-in-progress on end product (0.13 goal contributions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead. With this floor already at 22, the ceiling gets tested by a step up in level — one to track.

Market valueRating

Solid = now · dashed = projected

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around age 22 (~38), then tapers with age. At 22, Sauer sits on 38, still climbing toward its peak. The blue line is Sauer's projected Rating — 68.5 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.
