Vincent Olivier Sierro
Defensive · Parma · 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 5 seasons (2022/23–2025/26) across 3 clubs, including a move abroad — 102 appearances, 11 goals and 3 assists.
His best campaign on record is 2023/24 at Toulouse — Season rating 53, 6 goals and 2 assists in 30 games. 2023/24 was the leap — Season rating up 47 points at Toulouse. Form has slipped 37 Season points across his last 3 full seasons. The gap to his peak is 37 Season points.
A streaky profile — form has swung hard between campaigns (spread of ±20 points), so the peak and the trough are far apart.
