Watford manager Javi Gracia has warned his side will 'lose for sure' if they just try to defend at Liverpool.
The Hornets head to Anfield for Saturday's late kick-off looking for a response after a 3-0 defeat at Arsenal.
Liverpool, though, will be aiming to keep up the pace in the fight for second place in the Premier League, with rivals Tottenham and Manchester United both playing FA Cup quarter-finals.
Jurgen Klopp's men were beaten 2-1 at Old Trafford last weekend but have been in fine home form this season, with Mohamed Salah, Roberto Firmino and Sadio Mane spearheading the attack to deliver nine wins and no defeats from 15 matches.
