Why Jurgen Klopp's Red machine has malfunctioned: Fabinho's move into defence has upset the balance, Virgil van Dijk and Joe Gomez injuries have hit the side hard, while Mohamed Salah, Trent Alexander-Arnold and Co have hit a dip in form

The quip Bill Shankly once made to dismiss questions about Liverpool's form today rings true: here they are having problems at the top of the league.

Three lacklustre displays and two points from nine has given Jurgen Klopp much to consider in week one of the new year. Liverpool, suddenly, look vulnerable and the sombre mood among the players on the flight back from Southampton reflected the recognition that standards have dropped.

A huge fight beckons for last season's champions and if they are going to retain their title, Klopp needs to find solutions.
