Scout report
A. Sieb is a 23-year-old winger at Los Angeles FC, rated 70.7 overall by Field Insider's model, ranking 1st of 436 on scout potential in the Major League Soccer. An emerging talent, he has been a fringe squad member this season (29.5% of available minutes). He brings 0.39 goal contributions per 90 (0.39 goals, 0 assists). Below: strengths, watch-points, market-value outlook and the latest transfer news on Sieb.
Judged on this season alone, Sieb graded 17 — a workmanlike campaign that ranks 41st of 46 of the 46 wingers in the Major League Soccer, on 3 goals and 0 assists in 26 appearances (0.391 involvements per 90).
Year-on-year, that's broadly in line with last season (Season 15 → 13). Over the 5 seasons on record his form has trended upward, peaking in 2023/24.
On long-term talent our Rating reads 71, top 3% of the 46 wingers in the Major League Soccer. At 23 Sieb is still climbing toward his ceiling, and a market index of 13.2 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
Output in context · Los Angeles FC finished 3rd of 15 · an upper-table side
3 goals in 26 appearances (0.12 per game) — light end product the role wants to see climb.
Strengths
- Final-third output. 0.39 goal contributions per 90 (0.39 goals, 0 assists) — productive for the role.
Watch points
- Game time. Only 29.5% of available minutes — needs a settled run to prove the level.
Outlook
With a Rating of 70.7, Sieb carries the 1st-highest potential of the wingers in the Major League Soccer of 46 — though on just 26 appearances this season, so the standing rests on a small sample. In the final third he profiles as a productive contributor (0.39 goal contributions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. With this floor already at 23, the ceiling gets tested by a step up in level — one to track.
