Liverpool square off against Everton on Saturday afternoon looking to extend their club-record run over their Merseyside rivals.
Everton head into the encounter sitting above their neighbours in the Premier League standings after winning their first four fixtures this season.
However, Liverpool have not suffered defeat in their last 22 meetings against the Toffees in all competitions, a run stretching back to October 2010.
Should Jurgen Klopp's side prevail at Goodison Park, they will set a new mark for the amount of games that they have remained unbeaten against one opponent in succession.
Meanwhile, Everton are playing a Merseyside derby while placed in first position for the first time since September 1989, when they went on to suffer a 3-1 home defeat.
They have also gone six hours and 45 minutes without scoring a goal against Liverpool in a home league fixture, a run which began in October 2015.
