Liverpool and Manchester United fans warned they will be thrown out of Anfield if they sing about Hillsborough or Munich

Supporters caught singing about the Hillsborough or Munich disasters will be thrown out of Anfield on Monday night. 

An increased police presence is expected around the ground before and after the clash. Police chiefs are mindful of the potential for trouble, particularly given the ugly scenes earlier this year when illicit chanting and fighting marred the two fixtures. 

Problems centred on noises from the crowd, with United making sounds about the 1989 Hillsborough tragedy when 96 Liverpool supporters died at the FA Cup semi-final widely condemned after the first leg. 

Liverpool’s travelling fans at Old Trafford were also criticised after referencing the 1958 Munich air disaster, during which 23 people lost their lives.
