Liverpool moved back to within one point of Premier League leaders Manchester City and left neighbours Everton languishing in the bottom three after victory in the Merseyside derby.
Struggling Everton made Liverpool fight for their win with a well-organised and disciplined performance that will give them hope they can still avoid the drop but was not enough to deny Jurgen Klopp's quadruple-chasing side.
Liverpool can find different ways to get the job done and after blowing Manchester United aside on Tuesday they demonstrated patience to finally break down Everton's stubborn resistance in what could prove to be a priceless win.
