Fábio Vieira
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Fábio Vieira's performance-implied value at EUR 5.2M-27.4M, above the estimated acquisition range of EUR 6.8M-15.0M. Its 24-month market value projection is EUR 7.8M-20.6M. Context-adjusted goal contributions are 2.05x the positional average in the league (2217 minutes, league coefficient 0.94). Confidence is medium: no event-level data (xG, progressive actions) is available from the current free source, and injury history is unavailable.
Acquisition note: Final year of contract: selling club's leverage is reduced.
