It was only a question posed by Barry Ferguson.
But Ange Postecoglou insists Celtic have already provided the Rangers legend with the answer this season.
Ferguson threw down the gauntlet on these pages yesterday. Have Celtic got the bottle to get over the Premiership finishing line?
In fairness to the Record Sport columnist, he admitted he doesn’t have many doubt this Hoops squad does have the stones.
But by dangling the query out there, it just turned up the heat and extra notch when it’s already starting to get sweltering in the Premiership title race.
Postecoglou is not a man to get caught up in some of the off the pitch fun and games that surrounds the intense fight to be crowned champs.
And suggesting somehow his side’s stomach for the battle caused the kind of raised eyebrow not seen since Roger Moore was battling with Bloefeld.
Celtic haven’t lost in the league since last September. They’ve only drawn three games in 33 as well, to sit six points clear at the top – and with a colossal goal difference – with five games to go.
But defeat to Rangers in the Scottish Cup semis last weekend has offered some a glimmer of hope there could be a Premiership stumble on the horizon.
Maybe even against Ross County in Dingwall on Sunday.
When it was put to Postecoglou Celts hadn’t lost consecutive domestic games this season, he was quick to make a fact check.
“We haven’t lost in 33 games mate,” the Aussie said. “I think that’s testament to the group’s resilience along the way and how strong they have been, their mentality of making sure they perform at a consistent level.
“You don’t get that sort of form we have had over the last six months unless you are really strong mentally.
“Last week doesn’t really change that. It was a narrow loss. It could have gone either way. We are disappointed it didn’t go our way.
“But it doesn’t really change the fact that we have been in a strong position for a long time and played well for a long time.”
Postecoglou reckons pressure is for tyres. This part of the season is to be embraced – even if fans might want to buckle up.
He said: “I don’t think it’s unhealthy for people to feel anxious or nervous. That’s why we love it.
“If you could guarantee to everyone we’ll win the next five games then I’m sure some would be happy.
“But they’d be a bit bored as well, and probably lose interest after a while.
“The excitement of sport, of football, and supporting a team is that bit of unknown, we are on the edge.
“That’s why you enjoy it so much more when you get that success you deserve.
“Because you know you’ve had to be white-knuckled all the way through it.
“The last thing I want is our supporters to be flatlined, clapping and then going home not thinking about it.
“I’m sure it’s been a tough week for our supporters and we take responsibility for that.
“We want to make them feel better in the coming week and hopefully when you get off the ride at the end it will be worth it.”
The heat is on but Postecoglou won’t be sweating under his trademark jumper. He lives for this kind of stuff – and he demands his team feels the same.
The 56-year-old has won championships in his homeland and in Japan – with Yokohama F Marinos – and they have usually gone right to the wire, with Grand Finals in Oz and a final day showdown in the J-League when the top two sides met on the last weekend of the season.
Postecoglou said: “It came down to the very last game that year in Japan. It doesn’t always work out that way.
“But I’ve tried wherever I’ve been to create programmes and environments where you play your best football at the end of the year.
“That doesn’t mean you start slowly but whatever your starting point is, you should be finishing strong.
“That’s because of my experience in Australian football where the winner is decided by a Grand Final at the end of the year – after a final series.
“So there was no point in finishing first (in regular season) then stumbling your way through the finals as you wouldn’t end up champions.
“I think all my teams have played their best football come the end of the season and I think that’s why I’ve had success.
“That’s how we’ve hopefully designed it here and hopefully that’s what happens.
“It’s not guaranteed obviously but again, when I talk about the mindset and being resilient, we build that through the year.
“We’re constantly creating those kinds of pressurised situations for the players on a daily basis.
“So that when we get to this final part, it’s nothing new for them as they’ve embraced it all along.”
It will need clear minds and fresh legs. Which is why it was a worry for some Celtic fans to hear Reo Hatate talking about getting jet lag induced double vision and feeling physically and mentally zapped.
The Hoops looked uncharacteristically jaded at Hampden on Sunday but Postecoglou has no concerns over fitness.
As for Hatate, he said: “He is fine. With him, Daizen Maeda, Yosuke Ideguchi and Matty O’Riley, they’ve only come in the last three or four months. Whenever you come into a new environment, it is always challenging, particularly when you’re coming to a new country, but Reo’s fine. He’s training well.
“He’s all good.
“You are kind of guided by them, how they are playing and how they are training. I haven’t felt the need to sort of rein back any of them.
“From when they came in January they’ve been outstanding.”
