Where the market, the likely price and the model estimates sit.

Model value (performance-implied)€158k – €327k
Projected value (24 months)€80k – €216k
Dashed line: current market value (€200k). Bars are 20–80% model ranges; tick = median.

The model rates Liam Donnelly's performance-implied value at EUR 0.2M-0.3M, above the estimated acquisition range of EUR 0.0M-0.2M. Its 24-month market value projection is EUR 0.1M-0.2M. Context-adjusted goal contributions are 1.27x the positional average in the league (674 minutes, league coefficient 0.31). 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.

Risk profile

Overall: Very High

  • ▲Small sample: 674 league minutes last season.
  • ▲League level coefficient 0.31 (1.00 = big-five average): output may not translate.
  • ⚠No continental-competition minutes last season.
  • ⚠Contract ends in 11 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.

MoneyballAI identifies statistical opportunities from available data. A player flagged as a potential bargain is not guaranteed to succeed, to transfer, to rise in value, or to generate resale profit.
