Jürgen Klopp knows what is wrong with Liverpool. He just does not know how to fix it.

Liverpool struggles to defeat opponents near the foot of the Premier League and has the worst defensive record of the top eight teams. Even Middlesbrough, which is 17th, has conceded five goals fewer than Liverpool's 33.

Liverpool was considered a realistic title contender after beating Manchester City 1-0 on New Year's Eve. Since then, Liverpool has managed just one league win in seven with its hope of being champion gone. Finishing in the top four is now Liverpool's target — it is currently one point behind Arsenal, Saturday's visitor to Anfield which has a game in hand.
