Below his 2024/25 peak but holding a solid level — the platform for a return is there.
4.77 tackles, blocks & interceptions per 90 — solid defensive volume across 7 appearances. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.
Rated 14.2 overall — below regular-starter level. Defensively he reads as solid defensive volume (4.77 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).

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 31, Trondsen sits on 3.2, past its peak and easing. The blue line is Trondsen's projected Rating — 14.2 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.
