Callum Slattery
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Callum Slattery's performance-implied value at EUR 0.6M-1.1M, above the estimated acquisition range of EUR 0.3M-0.7M. Its 24-month market value projection is EUR 0.3M-0.9M. Context-adjusted goal contributions are 1.22x the positional average in the league (1927 minutes, league coefficient 0.31).
