Stuart Armstrong
Value picture
Where the market, the likely price and the model estimates sit.
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.
Bargain Index: not assigned

- ⚠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.
