Projected value (24 months)€384k – €1.3M
Dashed line: current market value (€2.0M). Bars are 20–80% model ranges; tick = median.

The model rates Callum McGregor's performance-implied value at EUR 0.9M-2.1M, above the estimated acquisition range of EUR 0.6M-2.1M. Its 24-month market value projection is EUR 0.4M-1.3M. Context-adjusted goal contributions are 0.62x the positional average in the league (2759 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.
