Sadio Mane and Virgil van Dijk both scored twice as Liverpool returned to their fluent best with an impressive 5-0 victory over Watford
The Premier League leaders raced into a 2-0 lead thanks to Mane's double in the opening 20 minutes, the second a brilliant backheel from the penalty spot
Divock Origi, starting only his second league game of the season, added the third in the 66th minute with a low strike
Van Dijk then headed in twice in the space of three minutes as Liverpool recorded their biggest victory of the season to stay a point clear of Manchester City at the top of the table
Liverpool's title bid has been dented in recent weeks with three draws in their last four league matches, but this was the perfect response against obliging opponents - as well as the ideal way to warm up for the Merseyside derby against Everton on Sunday, live on
Watford had conceded 11 goals on their previous two visits to Anfield and they were soon facing an uphill task again as Mane netted twice inside the opening 20 minutes
Starting in a central position in the absence of the injured Roberto Firmino, Mane opened the scoring in the eighth minute when he headed in from Trent Alexander-Arnold's cross
Alexander-Arnold and Mohamed Salah tormented Watford's left flank and it was no surprise that the former was involved in Liverpool's second goal in the 20th minute
Alexander-Arnold crossed into Mane, whose first touch took him away from goal, but with his second he finished with a superb backheel that bounced over Ben Foster
Liverpool looked rampant against a flimsy defence, with Salah hitting the inside of the post and Fabinho firing a powerful effort over from 25 yards out
Watford did threaten late in the first half but Troy Deeney turned wide from close range after being picked out by Gerard Deulofeu's low cross
Liverpool added a third in the 66th minute when Origi cut in from the left and hit a low shot that beat Foster at the near post
Substitute Andre Gray almost pulled a goal back for Watford as he saw an effort pushed away by Alisson, before the goalkeeper diverted a volley from Gray over the bar from point-blank range
But Liverpool had the final say as Van Dijk headed in from Alexander-Arnold's free-kick and then nodded in from Robertson's cross a few minutes later
Alexander-Arnold and Van Dijk were both excellent, but Mane set up the win with two early goals
 Playing in a more central position than he normally does, Mane made a good run for the first goal between Watford's centre-backs, and then produced a brilliant backheeled finish to extend Liverpool's lead
Liverpool make the short trip to Goodison Park to face Everton in the Merseyside derby on Sunday, live on
 They then host Burnley on Sunday, March 10
Watford are at home against Leicester on Sunday, live on , and then travel to Manchester City on Saturday, March 9
