Jim McIntyre got a crash course on Dundee’s season in his first game in charge.
The Dark Blues’ defensive fragility was clinically exposed by Livingston.
Four basic set-pieces resulted in four goals.
Ex-Dundee man Declan Gallagher scored the first – when Elliott Parish was caught in no man’s land and Ryan Inniss was out-jumped.
And Craig Halkett’s goal was perhaps even worse given the distance the ball travelled and the space he was afforded.
Then on 76 minutes a Steven Lawless inswinging set-piece was aimed at Alan Lithgow but he didn’t connect with his header and the ball flew past Parish into the back of his net.
In the 90th minute Lithgow got his goal – a backpost header from a Steven Lawson corner.
It wasn’t much better up front, with Livi keeper Liam Kelly barely tested.
In the second half there was a penalty shout when Moussa claimed Lawless used his arm to block a flick over him but that was as good as it got.
It certainly wasn’t the return to Livingston that their former player-manager Kenny Miller would have wanted.
He was far from alone by being well below his best, though.
The only good news on a dreadful afternoon for Dundee was that McIntyre will be left in no doubt about the scale of the task he faces.
