Projected value (24 months)€268k – €503k
Dashed line: current market value (€500k). Bars are 20–80% model ranges; tick = median.

The model rates Idrissa Gueye's performance-implied value at EUR 1.2M-4.2M, above the estimated acquisition range of EUR 0.2M-0.9M. Its 24-month market value projection is EUR 0.3M-0.5M. Context-adjusted goal contributions are 1.27x the positional average in the league (2102 minutes, league coefficient 1.30). Confidence is medium: 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. Market values, fees and contracts come from third-party sources; ranges are model estimates with stated confidence.
