Dashed line: current market value (€8.0M). Bars are 20–80% model ranges; tick = median.

The model rates Arthur's performance-implied value at EUR 6.9M-15.2M, above the estimated acquisition range of EUR 5.9M-12.2M. Its 24-month market value projection is EUR 5.0M-15.3M. Context-adjusted goal contributions are 0.85x the positional average in the league (1132 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.

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.
