THIS homecoming is not one of the bottle: it is a special one.
Five years, eight months and 14 days after Jose Mourinho was marched out of Stamford Bridge, he's back again – and it is tricky to think of a return that was ever in less need of additional hype.
He is gloriously happy: we know that, because he he said after the nightmare of Real Madrid that he would only go somewhere that made him so.
As far as the fans go: 'happy' doesn't do it justice. For most it seems like Christmas Day, Notting Hill Carnival and a lottery-win rolled into one.
But how about the person who really matters in all this? Well, Roman Abramovich isn't talking.
I never expected to see Jose back this summer. I knew it would happen one day, and said as much, but the steers I was getting from both camps were that the parties were too far apart.
But a lot has changed in the last few months. The last few weeks even. Enough to enable an irresistible force and immovable object to somehow meld together. For now.
Chelsea have had more of a bruising time over the appointment of Rafael Benitez than they care to admit.
They were desperate for fan-pleasing news. And the arrival of perhaps the most fan-pleasing news of all time, right on season ticket renewal deadline day, is surely a coincidence even bigger than your average Russian-registered super yacht.
They were also desperate for a big name manager. Since the departure of Carlo Ancelotti, the pool of coaching talent willing to dance to Kalinka at Cobham has been rapidly diminishing.
But the block to this appointment was never really at Chelsea.
The issue was always whether Jose would be willing to work within the constraints Chelsea expected to place on him.
His personal position has been changed by the disastrous final half-season or so at the Bernabeu. That polished sheen has lost a little of it's Special-ness.
Like the last two desperates at a singles evening, Chelsea and Jose could have gone home alone. But these two have history: and they know how fantastic it can be.
There are obviously risks here. Principally, we have no idea how the whole Abramovich / Mourinho / Michael Emenalo / Ron Gourlay thing is going to work.
Will an uneasy truce be established? A happy middle ground for the good of the kids? Maybe – but again, for how long?
Whatever the arrangement – it's going to have to be a special one.
