Clean sheets

1.97 tackles, blocks & interceptions per 90 — light defensive volume, with 5 clean sheets across 15 appearances. Behind a title-challenging side (2nd of 17) 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.

Strengths

Attacking threat. Chips in from deep: 0.41 goal involvements per 90, useful for a central defender.

Watch points

Game time. Only 35.9% of available minutes — needs a settled run to prove the level.
Defensive numbers. Modest 1.97 defensive actions per 90 for the position.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 44.1 overall — developing / rotation level. 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.

Market valueRating

Solid = now · dashed = projected

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 25, Sonne sits on 9.5, at or near its peak. The blue line is Sonne's projected Rating — 44.1 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.
