On long-term talent our Rating reads 20. At 28 Tønnessen is in his prime years, and a market index of 3.9 reflects that trajectory.
Below his 2020/21 peak but holding a solid level — the platform for a return is there.
3.16 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 9 appearances. Behind a title-challenging side (1st of 16) 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.
Rated 20.3 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.16 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 (~7), then tapers with age. At 28, Tønnessen sits on 3.9, past its peak and easing. The blue line is Tønnessen's projected Rating — 20.3 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.
