Watford’s Xisco Munoz is the first Premier League manager to be sacked this season.
He was removed hours after his newly promoted side lost one nil to Leeds United.
Watford – currently 14th in the table – have won two of their seven games.
A club statement read:
“Watford FC confirms Xisco Muñoz has left his post as the club’s Head Coach.
“The Board feels recent performances strongly indicate a negative trend at a time when team cohesion should be visibly improving.
“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.”
