And just like that, profound change is upon us.

Stewart Robertson, alongside Douglas Park and Ross Wilson, is now part of the club's history. Time will judge each better than this writer can in the here and now, but there can be no doubt each, at the very least, leaves Rangers in a stronger state than they found it. Regardless, everyone has a shelf life and Robertson himself has decided it's time for a new broom.

And yet, it's not completely new is it?

In appointing John Bennett as chairman, Micheal Beale as manager and James Bisgrove as CEO, the club has achieved an interesting balance of both continuity and reform. It could well prove the perfect blend. These men each know the club, their feet have been licked by flames and yet here they are, wanting more.

While Bennett offers experience, business savvy and meticulous attention to detail, the younger duo come into their jobs full of enthusiasm - but with eyes open. The hunger is there. The desire is there. The talent is there. And while neither was born of Rangers, you sense both understand exactly what the institution means.

At 38, Bisgrove is of a generation that intrinsically gets the digital era. Robertson, nearly 20 years his senior, had many qualities but he didn't ever seem too keen to be out front and centre, delivering messages. Better direct communication and engagement befitting a social media-driven culture will surely be at the forefront of the new CEO's mind. He's already committed to hosting a new quarterly CEO fans’ forum at Edmiston House alongside other members of the club's senior management. Rangers will not be analogue under a Bisgrove stewardship, we can already be sure of that.

A natural communicator, he will be a more visible figure at the front of this new-look Rangers management team. He's shown time and again how seriously he takes fan engagement during his tenure as commercial director, happy to discuss what's been happening at the club in detail and, crucially, take questions.

While some will point to the deal struck to see Rangers take part in the Sydney Super Cup as evidence of his failings, he also fronted up to the flak coming his way. He appeared on Rangers fan media podcast Heart and Hand to face the music and explain the thought processes behind the deeply unpopular agreement while others remained silent amid online fury that was glowing white hot.

People may have disagreed vehemently with what he had to say, but fronting up the decision showed character, something he's going to need by the bucket load in the months ahead. He's also learned some crucial lessons about the Rangers support and their red lines, not to be crossed. That will surely come in very handy in the years ahead. To paraphrase Rocky Balboa, 'It's not how hard you hit, it's about how hard you can get hit and keep on going.'

And make no mistake, he's stepped into a hugely rewarding job, but a few hits are inevitably coming his way in what will be the challenge of his life. After all, his success or failure will always be judged, perhaps unfairly, not on what he does behind the scenes but by what 11 men he barely knows do on the Govan grass.

And yet the rewards for getting things right are so incredible, Bisgrove couldn't possibly look the other way. He saw an aligned football department on the road to 55, he witnessed the power of Ibrox as Rangers pushed aside Dortmund and Leipzig to get to Seville and he knows how powerful it will be if he can be a unifier and pull everything back together.

He will be under no illusions doing so starts with a successful team on the pitch. Change is here, but in Glasgow, some things remain perpetually static.
