A career still climbing — Krollis is at his peak right now, and the curve hasn't flattened.
8 goals in 28 appearances (0.29 per game), a meaningful share of the load for a relegation-threatened side. Add 1 assist for 9 goal contributions in all.
With a Rating of 1.6, Krollis carries the 4th-highest potential of the centre-forwards in the Czech Liga (top 10%), and he is posting that for a relegation-threatened side (Slovan Liberec finished 6th of 6) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. In the final third he profiles as a productive contributor (0.45 goal contributions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 17–37 (~0), then tapers with age. At 24, Krollis sits on 0, at or near its peak. The blue line is Krollis's projected Rating — 1.6 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.
