Value picture

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

Estimated acquisition€370k – €1.1M
Model value (performance-implied)€717k – €2.1M
Projected value (24 months)€366k – €1.1M
Dashed line: current market value (€1.5M). Bars are 20–80% model ranges; tick = median.

The model rates João Mário's performance-implied value at EUR 0.7M-2.1M, above the estimated acquisition range of EUR 0.4M-1.1M. Its 24-month market value projection is EUR 0.4M-1.1M. Context-adjusted goal contributions are 0.52x the positional average in the league (1133 minutes, league coefficient 0.43). 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

  • ▲Age 33: resale value typically declines.
  • ⚠Limited sample: 1133 league minutes last season.
  • ⚠League level coefficient 0.43 (1.00 = big-five average): output may not translate.
  • ⚠Contract ends in 12 months: cheaper, but competition and wage demands likely.
  • ⚠Played under 40% of available league minutes (injury data unavailable, cause unknown).
  • ⚠Declining trajectory versus previous season.
  • ⓘInjury history unavailable from current data source.
