Clean sheets

1.76 tackles, blocks & interceptions per 90 — light defensive volume, with 6 clean sheets across 20 appearances. Behind an upper-table side (6th of 18) 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.

Strengths

Ceiling. High potential at just 22 — room to grow into a bigger role.

Watch points

Game time. Only 48.2% of available minutes — needs a settled run to prove the level.
Defensive numbers. Modest 1.76 defensive actions per 90 for the position.

Outlook

Rated 54.3 overall — a solid contributor and squad regular. Defensively he reads as light defensive volume (1.76 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead. With this floor already at 22, the ceiling gets tested by a step up in level — one to track.

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 (~17), then tapers with age. At 22, Mortensen sits on 16.3, still climbing toward its peak. The blue line is Mortensen's projected Rating — 54.3 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.
