The model rates Sam Kersten's performance-implied value at EUR 0.6M-1.2M, above the estimated acquisition range of EUR 0.6M-1.5M. Its 24-month market value projection is EUR 0.9M-2.3M.

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

Risk profile

Overall: High

  • ⚠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.
  • ⚠Declining trajectory versus previous season.
  • ⓘInjury history unavailable from current data source.
