Billy Gilmour
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Billy Gilmour's performance-implied value at EUR 12.4M-30.0M, above the estimated acquisition range of EUR 14.0M-25.8M. Its 24-month market value projection is EUR 8.9M-25.2M. Context-adjusted goal contributions are 0.73x the positional average in the league (802 minutes, league coefficient 0.93). Confidence is low: no event-level data (xG, progressive actions) is available from the current free source, and injury history is unavailable.
