Model value (performance-implied)€110k – €319k
Projected value (24 months)€133k – €259k
Dashed line: current market value (€250k). Bars are 20–80% model ranges; tick = median.

The model rates Nikolaos Karelis's performance-implied value at EUR 0.1M-0.3M, above the estimated acquisition range of EUR 0.1M-0.4M. Its 24-month market value projection is EUR 0.1M-0.3M. Context-adjusted goal contributions are 1.20x the positional average in the league (544 minutes, league coefficient 0.43). 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.
