Watford are in talks to appoint Claudio Ranieri as their new head coach after sacking Xisco Munoz.
Ranieri, who guided Leicester City to the Premier League title in 2016, left his role as Sampdoria manager at the end of last season.
Watford sacked head coach Xisco Munoz after less than 10 months in charge on Sunday morning, with the club 14th in the Premier League after winning seven points from their opening seven games.
Ranieri, who will turn 70 later this month and has also managed Chelsea and Fulham, is known very well by the Watford owners and Sky Sports News has been told he was a candidate for the managerial job in the past.
Watford are expected to have a new boss in charge ahead of their next Premier League game at home to Liverpool on October 16.
Spaniard Munoz replaced Vladimir Ivic in December 2020 and guided the club to automatic promotion from the Championship last season.
Munoz's last match in charge was a defeat against Leeds at Elland Road on Saturday - described as a "1-0 battering" by goalkeeper Ben Foster.
"The board feels recent performances strongly indicate a negative trend at a time when team cohesion should be visibly improving," the club said in a statement.
"The Hornets will always be grateful to Xisco for the part he played in securing last season's promotion and wish him well for his future career in football.
"No further club comment will be available until the imminent announcement of a new head coach."
Amid an overhaul of the club's squad following their promotion, Watford saw captain Troy Deeney leave after an 11-year stay while first-team regulars Will Hughes and Nathaniel Chalobah also left.
Munoz, who is the first manager to be sacked in the Premier League this season, started the new campaign with a 3-2 win against Aston Villa at Vicarage Road.
However, four defeats in six league games have followed that win, with their only other victory coming at fellow newly-promoted side Norwich.
Watford also exited the Carabao Cup at the third round stage to Championship club Stoke last month.
Munoz's departure means the club are looking for their 13th different permanent manager since the Pozzo family completed their takeover of Watford in 2012.
