Jurgen Klopp arrives at Vicarage Road on Saturday looking to banish memories of his Liverpool side's most recent visit to Herfordshire, a performance which will surely still haunt the German.
On February 29, 2020, Liverpool were flying. Top of the Premier League with a lead that grew week upon week, it seemed only a matter of time before the Reds would get their hands on a first league title in 30 years.
More pertinently, Liverpool's league record read: 26 wins, one draw, no defeats. With just 11 games remaining, Reds supporters travelled to Hertfordshire with a burgeoning confidence that Klopp's men could emulate Arsenal of 2003-04 and win the league as Invincibles.
