Watford showed little of the quality that sunk West Ham and Manchester United as Jeff Hendrick and Michael Keane gave Burnley victory.
Jeff Hendrick and Michael Keane scored their first Premier League goals as Burnley beat Watford 2-0 to taste victory for the first time in four top-flight outings.
Watford headed into the match with a devilishly tough opening set of fixtures behind them and buoyed by rousing successes over West Ham and Manchester United.
But they turned in a pedestrian effort at Turf Moor and had spent much of the contest on the retreat by the time Republic of Ireland midfielder Jeff Hendrick – a club-record signing from Derby County last month – headed the 38th-minute opener.
