Scout report
A. Sieb is a 23-year-old winger at FSV Mainz 05, rated 69.3 overall by Field Insider's model, ranking 134th of 325 on scout potential in the Bundesliga. An emerging talent, he has been a fringe squad member this season (23.2% 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 13 — a workmanlike campaign that ranks 10th of 11 of the 11 wingers in the Bundesliga, 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 69, 9th of 11 of the 11 wingers in the Bundesliga. At 23 Sieb is still climbing toward his ceiling, and a market index of 41.4 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 · FSV Mainz 05 finished 10th of 18 · a mid-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 23.2% of available minutes — needs a settled run to prove the level.
Outlook
With a Rating of 69.3, Sieb carries the 9th-highest potential of the wingers in the Bundesliga of 11 — 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.
