Scout report
F. Sierralta is a 29-year-old central defender at Auxerre, rated 39.3 overall by Field Insider's model, ranking 100th of 123 on scout potential in the Ligue 1. An experienced operator, he has been a fringe squad member this season (28.2% of available minutes). His defensive output reads 2.82 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Sierralta.
Judged on this season alone, Sierralta graded 14 — a workmanlike campaign that ranks 20th of 25 of the 25 centre-backs in the Ligue 1, on 3 clean sheets and 2.819 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 25 → 14). Over the 6 seasons on record his form has drifted down, peaking in 2020/21.
On long-term talent our Rating reads 39, 22nd of 25 of the 25 centre-backs in the Ligue 1. At 29 Sierralta is in his prime years, and a market index of 12.6 reflects that trajectory.
Below his 2020/21 peak but holding a solid level — the platform for a return is there.
Output in context · Auxerre finished 15th of 18 · a lower-table side
2.82 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 10 appearances. Doing that for a lower-table side (15th of 18) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
Watch points
- Game time. Only 28.2% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 39.3, Sierralta carries the 22nd-highest potential of the centre-backs in the Ligue 1 of 25 — though on just 10 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.82 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).
