Liverpool have been charged by UEFA for pitch invasions against Red Bull Salzburg.
Three supporters encroached on the Anfield turf at the end of Wednesday’s 4-3 win over the Austria Bundesliga outfit in their Champions League group game.
One person ran onto the field near the end of second-half added time and attempted to approach the dugout where both managers had been positioned.
A further two people approached for Andy Robertson and Trent Alexander-Arnold to ask for their respective match shirts following the final whistle.
European football’s governing body opened disciplinary proceedings against the Reds on Friday for the breach of Article 16 sub-section 2 of its regulations.
Salzburg are also set to face sanctions for objects thrown by their travelling supporters during the seven-goal thriller with Jurgen Klopp’s side.
UEFA’s Control, Ethics and Disciplinary Body will make a final ruling and issue potential financial penalties when it meets on October 17 to discuss the charges.
Klopp previously spoke out on the subject of pitch invaders after it led to Adrian suffering a freak injury during Liverpool’s Super Cup celebrations in Istanbul.
“There’s no doubt about how much we love our fans but if they could stop doing [pitch invasions],” he said at the tim.
“We played against Norwich, someone was running on the pitch. Istanbul as well.
“It’s not funny. I know it has uses like the girl in the Champions League final who made money from it but I don’t know what we can do against it.
“I like the fact that we don’t have fences in the stadium but that means there’s a lot of responsibility for the supporters as well.
“If one person cannot hesitate or stop himself then the people around should do it because it’s not funny.
“In this case now, it’s possible to watch it and it’s crazy to think ‘wow, how can something like this happen?’.”
If found guilty, Liverpool can expect an automatic fine of €5,000 (£4,458) in line with the federation’s process.
