We hold a single season for Martinec, so there's no year-on-year comparison to draw yet — the read above is this campaign only.
On long-term talent our Rating reads 1, 31st of 45 of the 45 centre-backs in the Czech Liga. At 28 Martinec is in his prime years, and a market index of 0 reflects that trajectory.
1.98 tackles, blocks & interceptions per 90 — light defensive volume, with 4 clean sheets across 16 appearances. Behind a title-challenging side (2nd of 6) 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. Going forward he chipped in 1 goal and 1 assist — a useful bonus from the back.
With a Rating of 1.1, Martinec carries the 31st-highest potential of the centre-backs in the Czech Liga of 45 — though on just 16 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (1.98 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

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 28, Martinec sits on 0, at or near its peak. The blue line is Martinec's projected Rating — 1.1 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.
