For a young player with only few data points, the Goalimpact estimates are subject to greater statistical uncertainty. Yet, the increase from 104.0 to 109.8 in just one month is superb. Segunda Liga was already finished in June, so the increase stems from his line-ups in the qualification to the U19 European Championships. In just five days, Portugal beat Bulgaria 7:0, Czech Republic 4:1 on foreign ground, and Denmark 1:0.
Transfermarkt.de lists him with a value of 400k€. The transfer window is still open. Why wait?
