Peer Koopmeiners
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Peer Koopmeiners's performance-implied value at EUR 1.1M-4.6M, below the estimated acquisition range of EUR 6.9M-13.6M. Its 24-month market value projection is EUR 5.1M-13.9M. Context-adjusted goal contributions are 0.44x the positional average in the league (2134 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.
