Clean sheets

5.97 tackles, blocks & interceptions per 90 — high defensive volume, with 1 clean sheet across 4 appearances. Behind an upper-table side (6th of 18) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume.

Defensive volume. 5.97 tackles, blocks & interceptions per 90 — does the unseen work.

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 (~20), then tapers with age. At 19, Leszczyński sits on 3.9, still climbing toward its peak. The blue line is Leszczyński's projected Rating — 33.9 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.
