Career report
Past his 2021/22 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
Peak: 2021/22Trending downStreaky
The record covers 6 seasons (2020/21–2025/26) across 3 clubs, including a move abroad — 142 appearances, 44 goals and 25 assists.

A streaky profile — form has swung hard between campaigns (spread of ±24 points), so the peak and the trough are far apart.
