Rui Patricio has said he was threatened with a broken jaw by one of the 50 football hooligans to attack Sporting Lisbon's players during training in 2018.
The Wolves goalkeeper was speaking at a Lisbon court hearing via Skype on Monday to give evidence about the attack on the Portugese clubs's playing squad and staff by football hooligans on May 15 that year.
The thugs attacked several players and staff and also wrecked the locker rooms at the club's training ground, and Patricio admitted that once they had entered the Alcochete academy he hoped that the hooligans 'don't kill us'.
'I was in the dressing room getting ready for practice when I heard noise and I noticed fans shouting in the dressing room, where the squad was mostly,' Patricio described.
'Vasco Fernandes, who was our technical secretary, tried to close the locker rroom door but he couldn't. They came in with their faces covered and started attacking.
'They didn't talk to anyone, they started attacking. They came in very aggressively. They came with everything. They came in, I don't know if they were coming to kill, but they came with everything.'
The Sporting players first told police that Argentines Marcos Acuna and Rodrigo Battaglia received the worst of the attacks.
Dutch international Bas Dost was also pictured with cuts on his head and reports said that assistant coaches Mario Monteiro and Raul Jose also suffered injuries.
They were reportedly kicked, punched and even received death threats as the thugs assaulted them.
'You could tell there was a lot of confusion. We didn't know who had been beaten up,' Patricio continued.
'There was confusion, there was smoke, there were shouts. When they entered the locker room they threw torches.
'We tried to calm them down, but they were very aggressive. They told us to take our shirts off they said 'you are a shame' and we are going to kill you. It was a very stressful moment.'
But Patricio said he was also verbally threatened in the incident.
After trying to separate one perpetrator from William Carvalho, 'three or four' more individuals grabbed the midfielder and began to punch him.
Patricio then said one of the members turned to him and said: 'Are you laughing? You want to leave, I'll break your jaw.'
After the attack, the Portuguese international said he saw Dost 'getting stitches in the head and head coach Jorge Jesus bleeding from his mouth and nose' when the coach went to the players in the dressing room.
Patricio's statement came as part of an ongoing trial of former president of Sporting Lisbon Bruno De Carvalho and 43 other defendants for their alleged roles in the incident.
The attack was allegedly motivated by the team's disappointing year in both the Portuguese League and the Champions League but prosecutors claim former club president De Carvalho 'ordered' the attack.
The decision for a trial came after the investigative judge found that there was sufficient evidence to continue with the case.
