O. Sonne is a 25-year-old full-back at Sparta Praha, rated 1.6 overall by Field Insider's model, ranking 58th of 321 in the Czech Liga. In his prime years, he has been a rotation option this season (35.9% of available minutes). His defensive output reads 1.97 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Sonne.
Judged on this season alone, Sonne graded 12 — a workmanlike campaign that ranks 30th of 50 of the 50 full-backs in the Czech Liga, on 5 clean sheets and 1.965 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 11 → 12). Over the 5 seasons on record his form has held fairly steady, peaking in 2023/24.
On long-term talent our Rating reads 2, top 18% of the 50 full-backs in the Czech Liga. At 25 Sonne is in his prime years, and a market index of 0 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
1.97 tackles, blocks & interceptions per 90 — light defensive volume, with 5 clean sheets across 15 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 2 goals and 3 assists — a useful bonus from the back.
With a Rating of 1.6, Sonne carries the 9th-highest potential of the full-backs in the Czech Liga (top 18%). Defensively he reads as light defensive volume (1.97 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
Generated from Field Insider's rating model · AI-written analysis to follow.
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 25, Sonne sits on 0, at or near its peak. The blue line is Sonne'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.
