Scout report
S. Duflos is a 31-year-old full-back at Boulogne, rated 27.8 overall by Field Insider's model, ranking 45th of 55 on scout potential in the Ligue 2. A seasoned veteran, he has been a rotation option this season (50.7% of available minutes). His defensive output reads 2.73 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Duflos.
Judged on this season alone, Duflos graded 21 — a workmanlike campaign that ranks 4th of 8 of the 8 full-backs in the Ligue 2, on 5 clean sheets and 2.726 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 3 → 21).
On long-term talent our Rating reads 28, 7th of 8 of the 8 full-backs in the Ligue 2. At 31 Duflos is into the veteran stage, where the age curve weighs on the projection, and a market index of 6 reflects that trajectory.
Output in context · Boulogne finished 15th of 18 · a lower-table side
2.73 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 30 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 0 goals and 3 assists — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.17 goal involvements per 90, useful for a full-back.
Watch points
- Game time. Only 50.7% of available minutes — needs a settled run to prove the level.
- Age curve. At 31, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 27.8, Duflos carries the 7th-highest potential of the full-backs in the Ligue 2 of 8, and he is posting that for a lower-table side (Boulogne finished 15th of 18) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (2.73 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
