Watford 0-5 Liverpool: Roberto Firmino's hat-trick sees Claudio Ranieri start reign with crushing defeat

Jurgen Klopp’s side dominated from the outset to extend their unbeaten league run to 18 games, with Sadio Mane opening the scoring with his 100th Premier League goal.

Firmino doubled Liverpool’s lead just before half-time with a tap-in before adding his second from close range seven minutes after the break, capitalising on a parry from goalkeeper Ben Foster.

Salah provided Liverpool’s fourth with another moment of individual brilliance in the box before curling the ball in to the far corner and Firmino completed his treble in added time.

It was not the welcome return to the Premier League that former Chelsea and Leicester boss Ranieri would have hoped for, after replacing the sacked Xisco Munoz, with the full scale of Watford’s bid to stay in the top flight evident.
