Slavisa Jokanovic has been appointed as head coach of Watford.
The 46-year-old former Chelsea midfielder replaces Billy McKinlay, who was only put in charge eight days ago.Jokanovic won successive Serbian titles whilst in charge of Partizan Belgrade and joins the Hornets from Hercules, who play in the Spanish third division.
Watford owner Gino Pozzo told the club's official website: "Our job is always to act in the best long-term interests of this football club. There can be no compromise on this - whatever the circumstances.
"I fully support and endorse the view from our technical staff that, given the talented squad which has been assembled and our position in the league, an experienced head coach with a winning pedigree is of primary importance to help ensure the success we are all striving for.
"The supporters of Watford have always been very understanding towards our project here and I am certain they will continue to do everything they can to support the new coach and his squad."
Former Scotland international McKinlay led the club for two matches, after Oscar Garcia departed for health reasons. Garcia had replaced Beppe Sannino, who left Vicarage Road in late August.
Jokanovic's appointment means he becomes the club's fourth head coach in just 37 days.
