Watford have sacked head coach Vladimir Ivic after four months in the role.
The Hornets, who have won nine of their 20 Championship games this season under Ivic, are fifth in the table, four points off second-placed Bournemouth and nine off leaders Norwich.
The 43-year-old signed a one-year deal in August, succeeding Nigel Pearson who was sacked shortly before the club were relegated from the Premier League.
It means Watford are looking for a fifth manager in just over a year.
The Serb's sacking came after his side were beaten 2-0 at mid-table Huddersfield Town on Saturday -just their second defeat in 11 games - a spell in which they have also had four draws.
