The model rates Jonathan Clauss's performance-implied value at EUR 0.9M-2.1M, below the estimated acquisition range of EUR 1.3M-4.0M. Its 24-month market value projection is EUR 0.8M-2.1M. Context-adjusted goal contributions are 1.09x the positional average in the league (2531 minutes, league coefficient 0.88). 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. Market values, fees and contracts come from third-party sources; ranges are model estimates with stated confidence.
