Ismaila Sarr was on target twice while Troy Deeney added a third as the Hornets dominated the league leaders at Vicarage Road.
FT: Watford 3-0 Liverpool
Reds still lead by 22 points
Following a cagey opening 45 minutes, Liverpool were no match for Watford after the break as Sarr scored a brace before setting up Troy Deeney to rock the League leaders.
Jurgen Klopp’s Reds would have set a new Premier League streak of 19 wins in a row had they collected yet another three points at Vicarage Road, but Nigel Pearson’s side fully deserved their vital win.
In truth, the result will do little to dent Liverpool’s title aspirations – but the manner of the defeat could be a concern for Klopp with their Champions League defence also hanging in the balance.
