Ivan Juric has left Southampton after the club's Premier League's relegation was confirmed, Sky Sports News understands.
The Saints became the earliest team ever to be relegated from England's top-flight, with their 3-1 defeat to Tottenham Hotspur seeing their demotion confirmed with seven games to go.
Juric's time at the south coast club lasted just 108 days. He was appointed in the week before Christmas and was handed an 18-month contract, with a break clause which would be reviewed at the end of the season.
The Croatian boss, who was dismissed by Roma after a dismal six-week spell last November, won just one out of his 14 Premier League games in charge - a 2-1 win over Ipswich at the start of February.
He lost 12 out of those 14 matches, with the Saints averaging 2.7 Premier League goals conceded under him.
