Projected value (24 months)€1.5M – €3.8M
Dashed line: current market value (€5.0M). Bars are 20–80% model ranges; tick = median.

The model rates Aarón Martín's performance-implied value at EUR 4.2M-9.6M, above the estimated acquisition range of EUR 1.4M-3.9M. Its 24-month market value projection is EUR 1.5M-3.8M. Context-adjusted goal contributions are 1.50x the positional average in the league (2161 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.

Acquisition note: Final year of contract: selling club's leverage is reduced.
