Roy Hodgson secured a point in his first game as Watford manager but his new side remain the relegation zone after a goalless draw at bottom side Burnley.
The visitors came closest to breaking the deadlock just before half-time, when Clarets skipper Ben Mee almost turned the ball into his own net from a corner.
Burnley's best chances came after the break, when Maxwel Cornet forced a decent save out of Ben Foster with a curling shot and £12m new-boy Wout Weghorst fired wide after being set-up by James Tarkowski.
But, in their first home game since the middle of December and only their 19th game of the season - the latest any side has reached the halfway point of a Premier League campaign - Sean Dyche's Burnley still lack conviction around the penalty area and have recorded a solitary win all season.
