Leon Bailey
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Leon Bailey's performance-implied value at EUR 15.7M-21.6M, above the estimated acquisition range of EUR 5.0M-13.1M. Its 24-month market value projection is EUR 3.7M-9.6M. Context-adjusted goal contributions are 0.71x the positional average in the league (634 minutes, league coefficient 1.30). Confidence is low: 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.
Bargain Index: not assigned
