Villarreal midfielder Alex Baena hit out at the "irreparable" and "unjustifiable" threats after he was allegedly assaulted by Real Madrid's Federico Valverde following Saturday's LaLiga match.
Baena played a full part in the contest at the Santiago Bernabeu and assisted Samuel Chukwueze's late goal as Villarreal beat Madrid 3-2.
According to sports newspaper AS and widespread reports, Baena was punched while looking at his phone when making his way to the Villarreal team bus.
It is alleged that Valverde assaulted Baena in retaliation to derogatory remarks the latter made about his unborn child in a previous encounter between the sides, claims the Villarreal man strongly denies.
Valverde was not referenced by name as Villarreal confirmed Baena had filed a police complaint in a statement on Sunday, in which the club expressed their support for the Spain youth international.
Baena took to social media on Monday to confirm he has lodged an official police complaint, while hitting out at the tirade of abuse that has followed towards him and his family.
A statement from Baena read: "Last Saturday I was attacked by a fellow colleague after the match against Real Madrid.
"After the event, various declarations came to light, presumably made by his entourage, in which it was said that I had wished pain for one of his family members.
"Since then, as it cannot be any other way, there has been no evidence that proves the facts that I am accused of.
"A misfortune was used to justify the aggression and there are lies that hurt more than blows.
"The damage that is being done to my family is irreparable and unjustifiable: threats, insults and even private messages wishing my family death.
"Yesterday I reported the case to the police. Let justice do its job. Now my only goal is to focus on my profession and help my club achieve its goals."
Valverde and Los Blancos have yet to comment on Saturday's alleged incident.
