Caps & goals this season.
S. Sebulonsen is a 26-year-old full-back at 1. FC Köln, rated 69.3 overall by Field Insider's model, ranking 134th of 325 in the Bundesliga. In his prime years, he has been an ever-present this season (89.8% of available minutes). His defensive output reads 2.26 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Sebulonsen.
Judged on this season alone, Sebulonsen graded 15 — a workmanlike campaign that ranks 44th of 55 of the 55 full-backs in the Bundesliga, on 2 clean sheets and 2.263 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 30 → 15). Over the 6 seasons on record his form has trended upward, peaking in 2024/25.
On long-term talent our Rating reads 69, 26th of 55 of the 55 full-backs in the Bundesliga. At 26 Sebulonsen is in his prime years, and a market index of 115 reflects that trajectory.
Read the appearance count in context: Sebulonsen missed 3 games through injury (muscle, yellow cards) out of roughly 34 this season. The 31 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
Below his 2024/25 peak but holding a solid level — the platform for a return is there.
2.26 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 31 appearances. Doing that for a lower-table side (14th 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.
With a Rating of 69.3, Sebulonsen carries the 26th-highest potential of the full-backs in the Bundesliga of 55, and he is posting that for a lower-table side (1. FC Köln finished 14th 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 (2.26 tackles, blocks & interceptions per 90). 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.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~115), then tapers with age. At 26, Sebulonsen sits on 115, at or near its peak. The blue line is Sebulonsen's projected Rating — 69.3 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
