The Premier League-winning manager of last season now finds himself in an unthinkable position just six months after lifting the English crown.
Liverpool’s title defence has descended into disarray and a humbling 4–1 home defeat to PSV in the Champions League has added yet another layer of uncertainty around Slot’s future on Merseyside.
Such is the mess that Liverpool find themselves in that Postecoglou - sacked by Tottenham in the summer and dismissed again by Nottingham Forest in October - is even being reported as a potential replacement.
Sources insist that scenario is doubtful, but the fact it is even being mentioned is alarming in itself.
The plan this season was to back Slot in the transfer market and extend his contract at the end of the campaign.
It has been a rocky year, and the club have given him time to iron out the flaws that have emerged… yet things appear to worsen by the week.
Internal briefings from the club have, until now, been consistent.
The message has been that Slot is here to stay and there would be no mid-season decision to remove him.
But can Liverpool really accept the season continuing in this manner?
The tragic death of Diogo Jota and the emotional impact on the squad cannot be overstated, while the club have also been patient as a raft of new signings attempt to settle after a heavy summer spend.
Until the PSV defeat, it was business as usual. There was a genuine determination to allow Slot the time to turn matters around.
But there is now a growing sense that he is losing the dressing room and, for the first time on Wednesday night, sources began to question how much longer he can remain in charge.
The attitude and application of his players in this latest defeat was telling - and PSV fully deserved their historic win.
Liverpool typically stand by their manager until a situation becomes irreparable.
A run of domestic fixtures against West Ham, Sunderland and Leeds could provide a platform to restore pride and competitiveness to a season rapidly slipping away.
But choosing to stand by Slot now represents a major call. Time will tell whether Liverpool truly believe in their manager.
