Robert Mühren
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Robert Mühren's performance-implied value at EUR 0.1M-0.3M, above the estimated acquisition range of EUR 0.0M-0.3M. Its 24-month market value projection is EUR 0.1M-0.1M. Context-adjusted goal contributions are 1.69x the positional average in the league (835 minutes, league coefficient 0.43). Confidence is low: no event-level data (xG, progressive actions) is available from the current free source, and injury history is unavailable.
Acquisition note: Contract end date unavailable: range widened by 15% each side.
Bargain Index: not assigned
