The model rates Jerolldino Bergraaf's performance-implied value at EUR 0.2M-0.4M, above the estimated acquisition range of EUR 0.2M-0.6M. Its 24-month market value projection is EUR 0.2M-0.8M. Context-adjusted goal contributions are 0.67x the positional average in the league (1046 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.

Acquisition note: Final year of contract: selling club's leverage is reduced.

Risk profile

Overall: High

  • ⚠Limited sample: 1046 league minutes last season.
  • ⚠League level coefficient 0.43 (1.00 = big-five average): output may not translate.
  • ⚠No continental-competition minutes last season.
  • ⚠Contract ends in 12 months: cheaper, but competition and wage demands likely.
  • ⚠Played under 40% of available league minutes (injury data unavailable, cause unknown).
  • ⓘInjury history unavailable from current data source.
