For the first time since January 3, 2019, Liverpool have tasted defeat in a Premier League match.
Ismaila Sarr's second-half double and Troy Deeney's strike earned relegation-threatened Watford a surprise 3-0 victory at Vicarage Road on Saturday.
Though it is unlikely to prevent the Reds from lifting the title - with Jurgen Klopp's side still 22 points clear of Manchester City - it did stop them from surpassing Arsenal's record sequence in Premier League history.
