Spurs' 1-0 triumph over Manchester United in Bilbao for their first trophy in 17 years has seemed to have prompted a whole new "Save Ange" wave of sentiment, with victorious club captain Son Heung-min offering the strongest support.
"He won the trophy. Nobody (else) did it," South Korean superstar Son said.
"Look, it's not up to me or the players, but we just have to look at the facts, at the fact we haven't won in 17 years and this is the day we finally won it. It's the manager who wins the trophy, so we see what's going to happen."
The silence was deafening from around Tottenham Hotspur Stadium as chairman Daniel Levy and his board, who had been said to have already decided on his sacking, may have been taken aback by the exultation from the fans over Postecoglou's drought-busting triumph.
As they pondered their next move, whether to allow Postecoglou to keep hold of the reins with Champions League football now secured, could the win really have saved the day for him?
"It's an unbelievable moment for Spurs. People asked me today, 'do you think the manager will go?' but how can you get rid of a manager who just won a European Cup?" Spurs' Irish great Robbie Keane asked on talkSPORT radio.
"You need stability at the club and you're not going to get that if you keep changing every couple of years. They need to build on this and build on momentum now," added the striker who was in Spurs's League Cup-winning team 17 years ago.
Son was far from alone among the Spurs squad going in to bat for Postecoglou.
Spurs' keeper Guglielmo Vicario, one of their big Bilbao heroes, declared: "Of course I want him to stay. He's my gaffer, he's the person who decided to bring me to this football club.
"I'm very happy for him, for what we achieved altogether. He told us this group is going to change something, it's going to change the history of this football club and we did it.
"Credit to him. He was the first to start to believe in something special and we did it."
Former Northern Ireland World Cup hero and Spurs star Gerry Armstrong told the BBC: "I'm backing Ange for next season.
"He deserves another year after what he has done and I'm hoping that winning the Europa League is going to make a difference."
