Projected value (24 months)€317k – €716k
Dashed line: current market value (€800k). Bars are 20–80% model ranges; tick = median.

The model rates Joan Sastre's performance-implied value at EUR 0.6M-1.4M, above the estimated acquisition range of EUR 0.1M-0.9M. Its 24-month market value projection is EUR 0.3M-0.7M. Confidence is low: no event-level data (xG, progressive actions) is available from the current free source, and injury history is unavailable.

Acquisition note: Contract end date unavailable: range widened by 15% each side.

MoneyballAI identifies statistical opportunities from available data. A player flagged as a potential bargain is not guaranteed to succeed, to transfer, to rise in value, or to generate resale profit.
