Liverpool manager Jurgen Klopp congratulated Watford after they became the first team in the Premier League this season to beat the Reds with a 3-0 win at Vicarage Road.

A second-half brace from Ismaila Sarr put the Hornets in control before the Senegal attacker set up Troy Deeney 18 minutes from time to provide the cherry on top of a fine performance from Nigel Pearson's side.

It ended the Reds unbeaten run of 44 league games, meaning they fall short of matching Arsenal's Invincibles from the 2003-04 campaign, who had gone the season and overall 49 matches without defeat.

The first Premier League loss for Liverpool in over a year does little to their hopes of winning the title, but ensured they missed out on equalling the record of the longest winning run in the history of the top five European leagues.

"I am not surprised by the performance because that would mean I never saw something like that before. I saw it a lot of times," Klopp said.

"What I can say and I think is 3-0 is a bit harsh, but we had a big hand in that so we don't have to think about that.

"The most important thing is congratulations Watford, well deserved. That is what should be the headline. We didn't perform like we should have and Watford performed exactly like they wanted."

After losing at Atletico Madrid on February 18, Liverpool have now suffered two defeats in three games in all competitions.

When quizzed on missing out on becoming an invincible like Arsenal, Klopp again reiterated he was not focused on that achievement.

"I don't think you can break records because you want to break records, you break records because you are 100 per cent focused on each step you have to do," he added.

"Tonight we were not good enough and it is not a plus for me that in history they will look back in 500 years and say Liverpool nearly did it.

"Nearly did it is not my main concern. We cannot change that and any time we will lose a game, we will lose a game.

"We didn't wait for it, but it was clear it would happen so we didn't think about it. We still knew it would happen and tonight it happened.

"I see it rather positive because the closer we get to these records, I am not bothered, but I am not sure how other people think about that so from now on we can play free football and don't have to defend or try to get the record. We just try to win football games again and that is what we will do."
