On long-term talent our Rating reads 15, 54th of 65 of the 65 central midfielders in the Superettan. At 30 Hallberg is into the veteran stage, where the age curve weighs on the projection, and a market index of 1 reflects that trajectory.
Below his 2024/25 peak but holding a solid level — the platform for a return is there.
1.14 tackles, blocks & interceptions per 90 — light defensive volume, with 7 clean sheets across 28 appearances. Behind a title-challenging side (2nd 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. Going forward he chipped in 1 goal and 3 assists — a useful bonus from the back.
With a Rating of 15.3, Hallberg carries the 54th-highest potential of the central midfielders in the Superettan of 65. Defensively he reads as light defensive volume (1.14 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).
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 23–27 (~2), then tapers with age. At 30, Hallberg sits on 1, past its peak and easing. The blue line is Hallberg's projected Rating — 15.3 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.
