MUCH can change in the space of six months.
It is a lesson Stuart Pearce will hope Derby County are made to learn this very weekend.
But, more significantly, it is one that the fans of Nottingham Forest are already embracing wholeheartedly themselves.
Because it is hard to imagine how things could have been more different for the Reds, ahead of the first East Midlands derby of the campaign.
As Billy Davies was driven away from the iPro Stadium in late March, following the last local derby, he wore the look of a man who was only too aware of his impending fate.
Slumped low down in the passenger seat as he was ferried off, probably in the direction of the departures lounge of East Midlands airport, the Scotsman himself looked beaten; defeated.
Regardless of his precise destination, Davies was certainly heading out of the exit at Forest. And, as he exited the car park with the taunts of Derby fans ringing in his ears, it was a single moment that perfectly personified Forest's malaise.
That was the club at their lowest ebb.
Having failed to acknowledge the thousands of Forest supporters who had made the journey down Brian Clough Way to witness the horror show that unfolded or, indeed, to offer any kind of explanation for the 5-0 drubbing – instead sending assistant manager Ned Kelly to face the difficult questions from the media – Davies skulked away.
Eight games without a win, their play-off hopes hanging by a thread and a growing division between the manager and the club hierarchy – there was a dark cloud hanging over Forest.
The performance and result against their fiercest rivals merely represented the first rumbles of thunder, ahead of the storm that was to follow.
But, following Davies' departure, the clouds have parted, the air is cleared and the sun is shining bright again, over the City Ground.
And this is not down to one man's exit. It is, more tellingly, because of the work done by his replacement.
Because, without straying too much into Alan Partridge territory, following the revolution, came the evolution.
And the memory of the fall out of that painful afternoon that brought about the end of an era, only serves to put a sharper focus on just how positive the mood is now.
Derby fans, for their part, will have taken as much glee in witnessing Forest's evident problems off the pitch, as they did what unfolded upon it, as the Reds edged ever closer to self destruction following their last meeting.
They may be looking on with some degree of trepidation now.
Derby are likely to be in the final shake up when it comes to the promotion race. Under Steve McClaren, who is a better coach than he demonstrated during his ill fated spell in charge at Forest, the Rams will still be a force to be reckoned with this season.
And they will provide the sternest test Forest have faced yet, when they visit on Sunday.
But, almost regardless of the result, there is one absolute certainty.
And that is that Derby will face a very different; a very much more difficult challenge themselves, as they did when the two sides last met.
Forest, under Pearce, are a hugely different prospect. This is not a side that will raise the white flag of surrender. He has put together a group of players with mental strength and character.
Equally, physically, it will be a very different team side – of the Forest team that started at the iPro (which was: Darlow, Lascelles, Fox, Collins, Jara, Greening, Mackie, Moussi (Henderson 45), Majewski, Paterson (Halford 64), Cox (Derbyshire 79). Subs not used: Harding, Osborn, Gomis, de Vries), only Karl Darlow is certain of his place in the starting line-up this weekend.
Otherwise, ten of the 18-man squad from March have left Forest and a further two have been told they have no future.
Jamaal Lascelles, Danny Fox and Jamie Paterson may find themselves on the bench this weekend. Or even in the stands.
This is not a fixture that will decide the outcome of the season.
But it is one that could perfectly embody the changes that have taken place at the club; one that could personify how significant the steps are that Forest have taken, in the space of just a few months.
Victory would cap off what already feels like an outstanding start to the campaign; one that has seen Forest unbeaten in seven games and sitting at the top of the early season Championship table.
But it is no exaggeration to say that even defeat would not completely dampen the sense of optimism at Forest, such has been the transformation.
When the sides last met, Davies' side were devoid of passion, motivation and organisation. They were picked apart by a Derby side who were well stocked with all three.
What are the chances of Forest being devoid of determination and grit this weekend?
Even if they do not play to their best; even if they were to have an off day, you can almost guarantee that, with Pearce on the touchline, they will be expected to fight for every ball; to contest every challenge as if their life depended on it.
It is the bare minimum that the manager demands.
On the way back from Bournemouth last month, Pearce ran into some Forest fans making the same journey home and stopped to chat.
"They were saying complimentary things about the club," said Pearce of his encounter.
"They talk about pride in the club and pride in wearing the shirt for the club. They want to see a passion. I think regaining the pride is an ongoing thing. You can lose it quickly.
"It takes months and years to gain a reputation, to gain pride. But you consistently have to say and do the right things.
"That is what you have to do. That is what we aim to do."
It is a fight Pearce is winning.
Forest have a new manager, a new squad, a new attitude and a new sense of belief.
Forest left what was formerly known as Pride Park with their's torn to shreds, back in March.
Conversely, they will emerge from the tunnel at the City Ground with their heads held high on Sunday afternoon, with their pride already fully restored by Pearce.
And you suspect, almost regardless of the result, they will return back down it with their dignity still in tact, a few hours later.
More importantly, there is a growing feeling that those who will fill the stands of what is certain to be a sold out City Ground, also now have a manager, a team and a club that they too can be proud to support.
