Below: strengths, watch-points, market-value outlook and the latest transfer news on Ronstadt.
Judged on this season alone, Ronstadt graded 8 — a workmanlike campaign that ranks 30th of 48 of the 48 full-backs in the 3. Liga, on 3 clean sheets and 1.487 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 8 → 8). Over the 6 seasons on record his form has trended upward, peaking in 2022/23.
On long-term talent our Rating reads 27, 37th of 48 of the 48 full-backs in the 3. Liga. At 28 Ronstadt is in his prime years, and a market index of 8.3 reflects that trajectory.
Past his 2022/23 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
1.49 tackles, blocks & interceptions per 90 — light defensive volume, with 3 clean sheets across 29 appearances. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
With a Rating of 26.6, Ronstadt carries the 37th-highest potential of the full-backs in the 3. Liga of 48 — though on just 29 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (1.49 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 23–27 (~14), then tapers with age. At 28, Ronstadt sits on 8.3, past its peak and easing. The blue line is Ronstadt's projected Rating — 26.6 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.
