Model value (performance-implied)€3.5M – €10.6M
Projected value (24 months)€1.3M – €3.9M
Dashed line: current market value (€5.0M). Bars are 20–80% model ranges; tick = median.

The model rates Boulaye Dia's performance-implied value at EUR 3.5M-10.6M, above the estimated acquisition range of EUR 2.6M-6.1M. Its 24-month market value projection is EUR 1.3M-3.9M. Context-adjusted goal contributions are 0.63x the positional average in the league (1250 minutes, league coefficient 0.93). Confidence is medium: no event-level data (xG, progressive actions) is available from the current free source, and injury history is unavailable.
