Projected value (24 months)€1.8M – €3.6M
Dashed line: current market value (€6.0M). Bars are 20–80% model ranges; tick = median.

The model rates Alessio Romagnoli's performance-implied value at EUR 3.2M-10.4M, above the estimated acquisition range of EUR 1.9M-4.9M. Its 24-month market value projection is EUR 1.8M-3.6M.
