Watford came from behind to beat Leicester 2-1 and seal a first Premier League victory in seven games.
A tap-in from Molla Wague and an own goal from Kasper Schmeichel cancelled out Leicester forward Riyad Mahrez's opener.
The victory was a first for Marco Silva's side since a 3-0 success at Newcastle on November 25.
The game got off to a spiky start with a flurry of early bookings dished out by referee Chris Kavanagh.
Leicester's Harry Maguire was first to go into the book, with the home side's Christian Kabasele and Ben Watson soon following him.
