Liverpool will call on "the full force of the law" to stop "vile chants" about the Hillsborough disaster.
The Premier League club pointed to a recent rise in the singing of songs about the tragedy - where 97 fans lost their lives as a result of a crush at an FA Cup semi-final in 1989.
The club said it was "saddened by the recent rise in vile chants".
On Wednesday, Manchester United condemned fans who chanted about the disaster 24 hours earlier.
Chants could be heard as the Old Trafford club faced Liverpool at Anfield and Manchester United later said the act was "completely unacceptable".
