This Rangers had not been seen for a while. Belligerent, but also good on the ball. Pacy, threatening, solid enough at the back even after they suffered the huge loss of their best defender, John Souttar, after little more than half an hour.

And this Ibrox was a force, too. Loud, deliriously happy, thunderously angry – an unsettling wall of noise.

All the while, Postecoglou waved and flapped and turned away in fury when one of his players – many of his players – went backwards.

What he had was a cavalry to call on. Kuluseveski was a game-changer. Dominic Solanke was a big presence, too, in the salvage job. They were both involved in the equaliser, Kulusevski finishing.

Postecoglou barely moved. Maybe his heart was singing. Maybe not.

It was frenetic and fractious in the 15 minutes that followed. Solanke came close, but Tavernier came up with a big defensive moment to deny him.

The Dessers chance was it. That was the moment, or could have been.

Forster got them out of jail, but Postecoglou’s trial goes on. One win in eight is an uncomfortable case for the defence.

For Rangers, a League Cup final to come at the weekend against Postecoglou’s old and firing team.

A few weeks back, that final looked like a bit of a formality for Celtic. Now? If Rangers can build on the best of this they’ll have something to say, for sure.
