Dashed line: current market value (€500k). Bars are 20–80% model ranges; tick = median.

The model rates Stephen Kingsley's performance-implied value at EUR 0.3M-0.8M, above the estimated acquisition range of EUR 0.1M-0.4M. Its 24-month market value projection is EUR 0.1M-0.5M. 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: Very High

  • ▲League level coefficient 0.31 (1.00 = big-five average): output may not translate.
  • ⚠Limited sample: 995 league minutes last season.
  • ⚠No continental-competition minutes last season.
  • ⚠Contract ends in 11 months: cheaper, but competition and wage demands likely.
  • ⚠Age 32: resale value typically declines.
  • ⚠Projection range wider than for most evaluated players.
  • ⚠Played under 40% of available league minutes (injury data unavailable, cause unknown).
  • ⓘInjury history unavailable from current data source.
