Dashed line: current market value (€200k). Bars are 20–80% model ranges; tick = median.

The model rates Stuart Armstrong's performance-implied value at EUR 0.2M-0.6M, above the estimated acquisition range of EUR 0.1M-0.2M. Its 24-month market value projection is EUR 0.1M-0.2M. Context-adjusted goal contributions are 1.48x the positional average in the league (1843 minutes, league coefficient 0.31). 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.
  • ▲Age 34: resale value typically declines.
  • ⚠No continental-competition minutes last season.
  • ⚠Contract ends in 11 months: cheaper, but competition and wage demands likely.
  • ⓘInjury history unavailable from current data source.
