It's fair to say that Liverpool's performances have been confusing this season. There haven't been many games in which we have seen Liverpool at their brilliant best.
However, the club are enjoying their best ever Premier League campaign in terms of points collected after 13 games (33 points).
The reds moved clear into second place, two points behind the impressive Man City. And whilst Man City sealed their points in the first half against West Ham, Liverpool elected to do their damage in the second half.
Watford were starting the day in 7th place and have had some good results over the course of this season, including a 2-1 home victory over Spurs.
Jurgen Klopp took advantage of Lovren and Henderson returning from international duty earlier than some of the other players - and both of those made a return to the first team.
Watford defended resolutely in the first half. There was little room for the reds to maneouvre in the lines between their defence and midfield. And the home team arguably had the best chances to take the lead in the first half.
The lively Roberto Pereyra with a shot that required Alisson to turn the ball away.
The home side claimed for a penalty when Will Hughes tumbled after a challenge from Andy Robertson. Replays didn't suggest much contact, if any, and the referee waved the appeals away.
In the 67th minute Liverpool made their breakthrough. Firmino, Mane combining and then the illustrious third man, Mo Salah, prodded the ball home.
Nine minutes later the reds won a free kick in a central position. Up stepped 20 year old Trent Alexander-Arnold to bend the ball around the wall and leave goalkeeper Ben Foster watching the ball sail into his net.
It was a special strike from the player who appears to have played himself back in to form over the past month.
Jordan Henderson collected a second yellow card in the final ten minutes of the game. It had been coming, and it arrived just seconds after he had received a talking to, and warning from, referee Jon Moss.
It wasn't a Liverpool masterclass by any stretch, but it's another three goals, three points and the reds continue to apply pressure near the top of the league.
Next up for the reds is the reverse Champions League clash against Paris Saint Germain.
