Bart Nieuwkoop
Value picture
Where the market, the likely price and the model estimates sit.
The model rates Bart Nieuwkoop's performance-implied value at EUR 0.5M-1.3M, above the estimated acquisition range of EUR 0.3M-1.1M. Its 24-month market value projection is EUR 0.5M-1.3M. Confidence is low: 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.
Bargain Index: not assigned

Overall: Very High
- ▲Small sample: 541 league minutes last season.
- ⚠League level coefficient 0.43 (1.00 = big-five average): output may not translate.
- ⚠Contract ends in 12 months: cheaper, but competition and wage demands likely.
- ⚠Age 30: resale value typically declines.
- ⚠Played under 40% of available league minutes (injury data unavailable, cause unknown).
- ⓘInjury history unavailable from current data source.
