Jurgen Klopp saluted Liverpool's record breakers after a 3-0 win at Watford extended their unbeaten run.

Mohamed Salah, Trent Alexander-Arnold and Roberto Firmino scored second-half goals to seal victory at Vicarage Road.

But Jordan Henderson will miss next weekend's Merseyside derby with Everton after being sent off late on for two bookings.

"They came back on Thursday, the Brazilians and Robbo (Andy Robertson) for example. With the demands on set-pieces, you need your own set-pieces, you need to work on the specific quality of the opponent."

Defeat leaves ninth-placed Watford winless in their last three games but they were furious after being denied a second-half penalty.

With the score level Robertson clipped Will Hughes in the box but referee Jon Moss ignored the hosts' protests.

Boss Javi Gracia said: "The last two games we have been unlucky with some decisions but I prefer to always support referees and if I don't say anything about their work in these two games I will not do it for the rest of the season.

"In these type of games you need to score if you have one chance.

"If you don't do it you know they are able to score."
