Attacking · Brighton · season-by-season, by competition, and every match.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
The record covers 6 seasons (2020/21–2025/26) across 4 clubs, including a move abroad — 160 appearances, 34 goals and 34 assists.
His best campaign on record is 2023/24 at Celtic — Season rating 65, 18 goals and 11 assists in 37 games. 2023/24 was the leap — Season rating up 29 points at Celtic. Form has slipped 54 Season points across his last 3 full seasons. The gap to his peak is 54 Season points.
A streaky profile — form has swung hard between campaigns (spread of ±18 points), so the peak and the trough are far apart. Made the jump to a higher division in 2022/23 (Premiership) and kept playing — 38 games that season.
