The Anfield club are already facing charges of illicit chanting and other crowd disturbances from their last-16 second leg draw with Manchester United at Old Trafford.

UEFA are still investigating claims Hillsborough and Munich songs were sung by rival fans at both Anfield and Old Trafford during the last-16 tie and further charges could yet follow.
