The incident occurred in the 83rd minute of the match at the Estadio da Luz. Former referee Eduardo Iturralde Gonzalez believes Valverde should have been sent off immediately.
If UEFA finds Valverde guilty of violent conduct, he could face a suspension, potentially missing next week's second leg at the Bernabeu. However, the report suggests the case is unlikely to result in a ban, as UEFA rarely punishes players when referees didn't initially penalize the incident.
