With a smoothly functional system, a reinvigorated Eden Hazard - who has already surpassed his total of six league goals from last season - and a Diego Costa who seems more minded to score goals instead of antagonising defenders, Conte's sparkling Chelsea are utterly unrecognisable from the rudderless group of individuals that were turned over in North London.
You can often get a feel for a new manager by the substitutions he makes to change a game. I'd just like to point out that Sam brought on Walcott and left Vardy, yeah you know the one that led Leicester to the Premier League title last season, on the bench. Still, he has taught Lallana to actually hit the back of the net so progress is being made, right?
You can't help but think this new Chelsea will be far more 'together' than they were in the opening months of last season. Mourinho's Chelsea were fractured; he'll have learned from his mistakes in his new role, but there'll be no more "palpable discord". Conte drives a hard bargain, and yes he's a little crazy, but he's respected.
Look, it's the New Year, it's that time of year to make some wild predictions and spend the next 12 months trying desperately to justify them, before giving up and trying to hide them by the time it gets to November and December. Then you go and do it all again in January. It's basically tradition... In that spirit, here's a nice, clear prediction that's next-to impossible to weasel out of: Chelsea will finish 2016 at the top of the Premier League table.
His valuation is sure to have skyrocketed over the past 15 months, but even if it's forty-five or even fifty million pounds, few can be considered as worthy of that outlay as he can. No disrespect to Everton, a fine club of proud traditions, but it surely can't be long until Lukaku's exploits are again picked up on slightly further afield.
Mourinho knows where the problems are in his team, is one of very few managers in the world whose track record suggests that he's got the skills to turn the current situation around and is stubborn enough to make the changes that are needed. If nothing's changed by, say, March, then the conversation becomes very different. But until then, as the kids say, #JoseIn.
The Premier League is highly regarded for its competitiveness, where anyone can genuinely beat anyone else on a given day - that kind of thing rarely happens in Spain and other European countries. There is no mystique or aura for defending English champions and it all means that when the naivety kicks in, as it has done in recent years, giants will always fall.
If it was naive to think that Chelsea were automatically favourites to win a second successive Premier League title ahead of the 2015/16 season - and it most certainly was - it's even more naive to think that now. Quite simply, Jose Mourinho's team have been left behind by their competitors and a terrible transfer window has now left them playing catch-up.
