Jurgen Klopp has enjoyed far more victories than defeats during his time at Liverpool, but the Anfield chief is adamant that last week's sorry surrender against Napoli is the worst he has seen his side play.
The Reds travelled to Naples in their Champions League opener against Luciano Spalletti's side with high hopes - but they were systematically dismantled by their Italian hosts. Liverpool found themselves 3-0 down at the break, but it could, and should, have been even more damning with Napoli missing a penalty and striking the post.
The Serie A outfit went on to win the match 4-1 to leave Liverpool with work to do in Group A. Speaking ahead of Tuesday night's crunch clash with Ajax, Klopp admitted: "We had a meeting with the players, I watched the [Napoli] game and it was a real horror, to be honest. It was the worst game we played since I am here."
