It's one of the biggest rivalries in football, and when Liverpool take on Manchester United at Anfield on Sunday, the hosts will be putting in an extra special effort to put United to the sword, by trouncing them and getting their Norwegian boss, Ole Gunnar Solskjaer, the sack.
Liverpool sit at the top of the Premier League with what some would say is an unassailable 14-point cushion - having played a game less than their closest rivals, Manchester City - whilst all United can do is try to hang on to their shirt tails, as the Merseyside club march towards their first title in 30 years.
United have made Harry Maguire captain, but, said Liverpool boss, Jürgen Klopp:
"We don't care who's captain. They can make Bobby Charlton captain if they want. We'll be going after them tomorrow, and I've told the players to try and score a hatful, and get their manager the boot."
Jordan Henderson said:
"We all hate United, and their fans. Nothing will be sweeter than seeing them sulking back onto their bus after a good, old-fashioned pasting!"
The teams drew 1-1 at Old Trafford in November, in the only one of Liverpool's Premier League games this season where they haven't taken all three points.
"They spoilt our 100% record. Now it's payback time. Ole's history!"
