Two goals from Odion Ighalo helped to give Watford an impressive 3-0 win over Liverpool at Vicarage Road on Sunday, their fourth consecutive Premier League triumph.
A dreadful mistake from Adam Bogdan, who was replacing the injured Simon Mignolet in Liverpool's goal, allowed Nathan Ake to score a simple opener.
The convincing win puts in-form Watford within one point of Tottenham in fourth place, while Liverpool remain ninth and have now won only three of nine league games since Jurgen Klopp took charge after a poor performance.
Liverpool made four alterations to their team as Bogdan, Roberto Firmino, Lucas Leiva and Mamadou Sakho came in for injured trio Dejan Lovren, Mignolet and James Milner, while Christian Benteke dropped to the bench.
Watford, who were unchanged, made a dream start in the third minute. Bogdan somehow dropped Ben Watson's corner under little pressure, allowing Ake the simplest of tasks to tap home from a yard out as referee Mark Clattenburg ignored the keeper's claims that he had regained control before the defender struck.
The Reds looked fired up after the break and Origi shot straight at Gomes, but it was almost game over when Jurado played a pass through to Ighalo and Sakho slipped to allow him through on goal, with Bogdan having to make a vital save.
At the other end, Jordan Henderson forced his way past Ake and struck powerfully towards goal, but Gomes made an important one-handed stop to preserve Watford's two-goal advantage.
Emre Can had a long-range effort beaten away by Gomes, but there was to be no recovery as Liverpool's disappointing run of form continued.
