S. Sonnenberg is a 27-year-old central defender at FC Saarbrücken, rated 27.2 overall by Field Insider's model. In his prime years, he has been a fringe squad member this season (13.6% of available minutes). His defensive output reads 5.81 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Sonnenberg.
On the season, Sonnenberg graded 7 for current form (age-blind), on 1 clean sheet and 5.806 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 18 → 7). Over the 6 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 27. At 27 Sonnenberg is in his prime years, and a market index of 14.1 reflects that trajectory.
Below his 2022/23 peak but holding a solid level — the platform for a return is there.
5.81 tackles, blocks & interceptions per 90 — high defensive volume, with 1 clean sheet across 19 appearances. Doing that for a lower-table side (15th of 20) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight.
Rated 27.2 overall — below regular-starter level. Defensively he reads as high defensive volume (5.81 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

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 27, Sonnenberg sits on 14.1, at or near its peak. The blue line is Sonnenberg's projected Rating — 27.2 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.
