And so the unthinkable happened. Dozy drawing specialists in mediocrity Manchester United took champions elect Chelsea to the cleaners. Hand the title to Tottenham - it's all over. Except that it wasn't unthinkable at all. And it isn't a disaster for the side still four points clear of the chasing pack.
For Antonio Conte, it looked like he'd lost an aunt: so personally does he take each and every defeat, that it is almost appropriate that he enters these press conferences in funereal black. But that period of mourning really was no more grief-stricken than any other he has publicly suffered this season. And Conte knows a thing or two about 'suffering' – he tells us about his teams suffering each and every week.
Conte knew his side was well beaten: he told us they deserved defeat. Moments earlier, his opposite number had explained how he had undone Conte.
Jose Mourinho, sometimes unfairly characterised as a tactical wrecking ball, got this one just right: man mark Eden Hazard and Pedro out of the game, and take the oxygen of space away from the wing-backs. It was a legitimate tactical gambit, and it worked, with the added pace of Marcus Rashford causing merry hell periodically.
Chelsea, truth be told, seemed to start with a form of psychological disadvantage here. Their settled XI is so finely formed that each time one of the band of brothers is absent, there seems to be additional suffering.
Here it was Marcos Alonso, who suffered an overnight illness, and Thibaut Courtois - the precise reasons for whose suffering may end up being a point to generate quite some column inches in coming days. Arguably, you could add Diego Costa to that list: present in physical form, but very little else.
So this was Chelsea going into their toughest remaining game with three men down, and against a manager for whom this was his cup final. If you think that final point is unkind, Mourinho did actually say as much, using the afterglow of one of his new side's best wins to grumble about the injustice of missing out on a walk down Wembley Way against Tottenham next Saturday evening.
