Projected value (24 months)€6.6M – €17.4M
Dashed line: current market value (€12.0M). Bars are 20–80% model ranges; tick = median.

The model rates Ilia Gruev's performance-implied value at EUR 4.9M-16.8M, above the estimated acquisition range of EUR 5.5M-11.8M. Its 24-month market value projection is EUR 6.6M-17.4M. Context-adjusted goal contributions are 1.73x the positional average in the league (1324 minutes, league coefficient 1.30). 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.

MoneyballAI identifies statistical opportunities from available data. A player flagged as a potential bargain is not guaranteed to succeed, to transfer, to rise in value, or to generate resale profit.
