Dundee United have sacked Jack Ross following their record home defeat to Celtic.
The former Alloa, St Mirren, Sunderland and Hibernian manager lasted just seven games in charge.
United lost 9-0 to Celtic on Sunday to make it five straight defeats and 23 goals conceded in their last four games.
A club statement read: “Dundee United can confirm that head coach Jack Ross has been relieved of his duties with immediate effect.
“Liam Fox will take care of the caretaker first team with his full focus now on Wednesday’s Premier Sports Cup tie with Livingston.”
Ross was appointed on June 20 following the departure of Tam Courts from Hungarian side Honved.
The 46-year-old started his reign with a Premiership draw with Kilmarnock and then a 1-0 Europa Conference League win against AZ Alkmaar in Tannadice.
However, after a 1-0 home loss to Livingston, United went down 7-0 in the Netherlands to equal the worst result by a Scottish club in European competition.
A 4-1 loss to Hearts and a 3-0 home loss to St Mirren were followed by another capitulation to Celtic.
Ross said after Sunday’s loss he was determined to turn things around.
“It doesn’t matter what club I am at or at what level, I had the same desire to do well as a manager at Alloa as I do now,” he said.
“And because of the embarrassment and humiliation I feel right now, I absolutely want to address it.”
