Sem Steijn
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Sem Steijn's performance-implied value at EUR 1.3M-7.7M, below the estimated acquisition range of EUR 5.5M-12.2M. Its 24-month market value projection is EUR 5.0M-14.6M. Context-adjusted goal contributions are 0.79x the positional average in the league (1108 minutes, league coefficient 0.43). Confidence is medium: no event-level data (xG, progressive actions) is available from the current free source, and injury history is unavailable.
