Liverpool have been charged with illicit chants and the setting off of fireworks after their Europa League showdown against Manchester United last night.
Both sides have been charged with crowd disturbances and throwing of objects, but Manchester United have avoided being charged over chants that were reportedly heard inside Old Trafford regarding the Hillsborough disaster.
Both sets of fans were seen fighting in the stands last night after Liverpool supporters unfurled a banner in the Manchester United end. The case will be heard by Uefa's control, ethics and disciplinary body on 19 May, the day after the Europa League final in Basel.
Tensions were high following the first leg last week at Anfield, during which some Manchester United fans were heard chanting about Hillsborough. UEFA subsequently announced they would not be taking any action against the club.
Now though, European football's governing body have come down on both sides, although Liverpool fans were less than impressed that their rivals hadn't been charged over the chanting. You can check out the reaction below.
Before the game, Greater Manchester Police were forced to remove a banner which read 'Murderers' along with the date of the Hillsborough disaster, hung over a motorway leading into Manchester to attract the attention of travelling fans.
Greater Manchester Police superintendent Jim Liggett said the force was investigating a "handful of concerning incidents" after Thursday's game.
Neither Manchester United or Liverpool have officially commented on the charges as yet.
Liverpool ran out 3-1 winners on aggregate after securing a 1-1 draw last night. Anthony Martial opened the scoring from the penalty spot after he was brought down by Nathaniel Clyne with 32 minutes gone.
However, Philippe Coutinho levelled things up on the stroke of half-time with a stunning solo goal that effectively ended the tie as a competition.
"I am not angry, I am not frustrated," under-fire Manchester United boss Louis Van Gaal said. "We have created a lot of chances but they scored the away goal. That was the difference.
"I hope Man City on Sunday will be the catalyst. We shall do everything that we did today."
Liverpool are now in the hat for the Europa League quarter-finals draw, which takes place in Switzerland this afternoon.
