Value picture

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

Model value (performance-implied)€889k – €1.1M
Projected value (24 months)€375k – €973k
Dashed line: current market value (€700k). Bars are 20–80% model ranges; tick = median.

The model rates Halil Dervişoğlu's performance-implied value at EUR 0.9M-1.1M, above the estimated acquisition range of EUR 0.2M-0.6M. Its 24-month market value projection is EUR 0.4M-1.0M. Context-adjusted goal contributions are 0.62x the positional average in the league (855 minutes, league coefficient 0.40). 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: 855 league minutes last season.
  • ⚠League level coefficient 0.40 (1.00 = big-five average): output may not translate.
  • ⚠No continental-competition minutes last season.
  • ⚠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.
