Tackles

Interceptions

Clean sheets

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.

Strengths

Attacking threat. Chips in from deep: 0.33 goal involvements per 90, useful for a central midfielder.

Watch points

Game time. Only 40.8% of available minutes — needs a settled run to prove the level.
Defensive numbers. Modest 1.14 defensive actions per 90 for the position.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 15.3, Hallberg carries the 53rd-highest potential of the central midfielders in the Superettan of 64. 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).

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 (~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.
