Liverpool’s hopes of remaining unbeaten for an entire Premier League season were ended in sensational style by a rampant Watford at Vicarage Road.
Ismaila Sarr scored twice while captain Troy Deeney added a third in a sparkling second-half display from the hosts as Liverpool’s run of victories was brought to a shuddering halt.
The Reds had won their past 18 Premier League games and another at Vicarage Road would have made history as the longest winning run in the English top flight.
But they never got going against a Watford side who were superb from start to finish.
The Hornets had more chances in the first half and only a superb save from Alisson, to deny Troy Deeney, prevented them from leading at the break.
However, Watford deservedly took the lead when Abdoulaye Doucoure squeezed a cross in from the left and the impressive Sarr was there to stab in.
Liverpool had fallen behind against West Ham last week but still managed to grind out a win. However, there was a feeling that this time was different, with the Reds sloppy in possession and lacking bite in attack.
It was no surprise that Watford doubled their advantage. Sarr was put through on goal by Will Hughes and the winger calmly lifted the ball over Alisson and into the net.
Captain Deeney then completed a famous victory, curling into the back of the net from the edge of the area.
This is not a result that is going to halt Liverpool’s title charge with the Reds 22 points clear at the top but it was nevertheless an unexpected and memorable result for Watford.
Sarr the star for superb Watford
Many had arrived at Vicarage Road expecting to see Liverpool make history by winning in the league for the 19th game in a row.
Indeed, such was the level of expectation that press accreditation for the game had been oversubscribed, with hundreds of media outlets keen to cover a moment in English football history.
But Watford were clearly not reading from the same script.
A superb run of four wins in five games at the start of Nigel Pearson’s reign had lifted them up from the foot of the table and out of the relegation zone but five games without victory prior to the visit of Liverpool had dropped them back into trouble.
Despite the recent poor run of results, performances had still been good and they were boosted for this game by the return from injury of Sarr.
The winger has been a real creative spark for the Hornets this season, and he was a menace from the outset, taking advantage of the surprising amount of space he was afforded on the wing to deliver a number of dangerous crosses.
His pace and trickery unsettled the Reds who were unable to handle him and both his goals were taken with an assured calmness.
If he can remain fit for the remaining 10 games of the season then Watford have a real chance of retaining their Premier League status.
