All Eredivisie standouts →One of the biggest game-time risers in the Eredivisie: on the pitch for 77% of Excelsior's available minutes this season, up from 17% last year — a bench-to-starter jump the ratings will catch up with at the next checkpoint.
S. Janssen is a 26-year-old full-back at Excelsior, rated 50.2 overall by Field Insider's model, ranking 93rd of 159 on scout potential in the Eredivisie. In his prime years, he has been a fringe squad member this season (16.9% of available minutes). His defensive output reads 2.79 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Janssen.
Judged on this season alone, Janssen graded 5 — a workmanlike campaign that ranks 29th of 29 of the 29 full-backs in the Eredivisie, on 1 clean sheet and 2.785 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 5 → 5). Over the 7 seasons on record his form has held fairly steady, peaking in 2021/22.
On long-term talent our Rating reads 50, 17th of 29 of the 29 full-backs in the Eredivisie. At 26 Janssen is in his prime years, and a market index of 23.1 reflects that trajectory.
Past his 2021/22 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
Output in context · Excelsior finished 13th of 18 · a lower-table side
2.79 tackles, blocks & interceptions per 90 — moderate defensive volume, with 1 clean sheet across 13 appearances. Doing that for a lower-table side (13th 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 1 assist — 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 16.9% of available minutes — needs a settled run to prove the level.
Outlook
With a Rating of 50.2, Janssen carries the 17th-highest potential of the full-backs in the Eredivisie of 29 — though on just 13 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.79 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around. Doing it for a lesser side, he profiles as a value buy for a club higher up the table.
