Dashed line: current market value (€3.0M). Bars are 20–80% model ranges; tick = median.

The model rates Jesper Karlsson's performance-implied value at EUR 1.5M-3.2M, above the estimated acquisition range of EUR 0.9M-2.6M. Its 24-month market value projection is EUR 1.0M-3.0M. Context-adjusted goal contributions are 1.16x the positional average in the league (1823 minutes, league coefficient 0.31). Confidence is medium: no event-level data (xG, progressive actions) is available from the current free source, and injury history is unavailable.
