Petros Mantalos
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Petros Mantalos's performance-implied value at EUR 0.4M-1.7M, above the estimated acquisition range of EUR 0.2M-0.6M. Its 24-month market value projection is EUR 0.2M-0.5M. Context-adjusted goal contributions are 0.78x the positional average in the league (1175 minutes, league coefficient 0.43).
