Kaj Sierhuis
Center Forward · NEC Nijmegen · season-by-season, by competition, and every match.
Below his 2023/24 peak but holding a solid level — the platform for a return is there.
The record covers 7 seasons (2020/21–2025/26) across 4 clubs, including a move abroad — 132 appearances, 31 goals and 9 assists.
His best campaign on record is 2023/24 at Fortuna Sittard — Season rating 51, 12 goals and 3 assists in 31 games. 2023/24 was the leap — Season rating up 51 points at Fortuna Sittard. Output has held steady across his last 3 full seasons (51 → 46). The gap to his peak is 5 Season points.
A streaky profile — form has swung hard between campaigns (spread of ±20 points), so the peak and the trough are far apart.
