When Derek McInnes one day leaves Pittodrie there will be one undeniable fact about his time in charge of Aberdeen - he transformed the club from a struggling spent force into one of the best teams in Scotland.
The Dons have consistently been the second best team in the country for a number of years now and while this season both Rangers and Celtic may finish above them in the Scottish Premiership, there is still a chance to show both Glasgow sides up by securing the glittering prize that is the Scottish Cup, an occasion you can use your Unibet bonus code on.
That’s massive of course, because despite the turnaround of Aberdeen’s fortunes under McInnes there remains another defining narrative of his time in charge - he should have brought more silverware to the city.
A solitary Scottish League Cup win in 2013/14 won’t cut the mustard when it comes to appraising his legacy and impact on the club since taking over from Craig Brown over six years ago.
There have been semi-finals, there have been finals but because those have ultimately ended in disappointments at Hampden then there would always be ‘what ifs’, there would always be regrets.
Luckily for McInnes, his best chance of cementing that legacy as an Aberdeen legend comes this season. The big barrier to that is firmly in view too, it comes this Sunday against a treble-chasing Celtic side.
Yes the Dons’ record against the Hoops in cup competitions in recent years is dire. It’s also true that there’s a mismatch in budgets and in first-team talent. There’s absolutely no doubt that the odds are stacked against McInnes’ team.
However, there’s an argument to say Celtic are more vulnerable now than they have been for years.
The departure of Brendan Rodgers to Leicester City and arrival of Neil Lennon has brought uncertainty and anxiety to a usually gallus Hoops support.
Not many of them are relishing a trip to Hampden to face a team that ground out a 0-0 stalemate at Celtic Park just a few weeks ago, a match that the Dons arguably should have won.
Aberdeen on the other hand have reason to feel confident. In addition to that draw against the champions-elect recently there have been wins against Rangers in Glasgow in two cup competitions and in the league. McInnes’ side are travelling well to the city this season.
Big games suddenly feel like occasions that the team can rise to instead of wither away from.
McInnes will never have a better chance to finally see the potential of his Aberdeen reign fully realised on the national stage.
This is his big chance. Can he deliver?
