Whether the aforementioned factors will be enough for Levy to hold his nerve remains to be seen.
Levy said he had “shared in that pain and frustration” of the fans this season before the Europa League triumph, and thanked Postecoglou and the players for “making this incredible achievement possible”.
He added: “This is one trophy – our clear ambition as a club has always been long-term, sustained success, competing for top honours every year.”
Much of what transpires in the next 72 hours will depend on whether the chairman has been swayed by the emotion since Bilbao.
History tells us Levy can be ruthless. He sacked Mauricio Pochettino just six months after he led Tottenham to the 2019 Champions League final, where they lost to Liverpool.
He also sacked Jose Mourinho just days before the 2021 Carabao Cup final, which they lost to Manchester City.
The evidence indicates Levy pays little attention to emotion.
That said, you’d have to be a robot not to have been guided by the outpouring of love towards Postecoglou this week.
The former Celtic boss intends to go on holiday early this week, so there will be a desire to resolve his future before he jets off.
His intriguing address to supporters during the parade reception on Friday night captured the imagination.
“I’ll leave you with this: in all the best television series, season three is better than season two,” roared Postecoglou.
Perhaps he knows something we don’t. Perhaps he doesn’t.
We’re about to find out.
