The memories were still raw of another unnecessary surrender when Jurgen Klopp and his coaching staff chose to address the issue with his Liverpool players.
The Reds had seen a two-goal lead slip in a 2-2 draw at title rivals Chelsea on January 2 in the last game before the departure of their Africa Cup of Nations trio and, in particular, Sadio Mane and Mohamed Salah, whose goals had put the visitors in a commanding early position that afternoon.
Worryingly, it wasn't the first time it had happened this season, Liverpool eventually escaping with a victory at Atletico Madrid in the Champions League in October but pegged back in a frustrating stalemate at home to Brighton less than a fortnight later.
