Chelsea made Jose Mourinho's return to Stamford Bridge with Manchester United a day to forget as they thumped four goals past the hapless Red Devils.

Much was made of the Special One's return but he was largely ignored for the best part of 90 minutes.

He was told by some fans in the East Stand that he wasn't special anymore at 2-0 after Pedro and Gary Cahill netted and then chants of 'You're getting sacked in the morning' when the Blues went 3-0 up thanks to Eden Hazard's goal.

However, at 4-0 after N'Golo Kante's strike, Chelsea fans roused into a cheer of 'Jose Mourinho' that you couldn't help but feel was in sympathy to the twice-axed Blues boss.

Here are the five talking points to emerge from Stamford Bridge.

The King is dead, long live the King

The moving finger: Antonio Conte celebrates (we think)

Pre-match we wondered just how great the hero worship would be. After it, we realised we were looking at the wrong hero.

Antonio Conte will have very far to go before he comes close to emulating Jose Mourinho's glorious achievements at Chelsea.

But, for the first time here, we saw his team emerge from the shadow of it's former chief.

Conte's side was brutal in its destruction of Mourinho's United: whatever excuses that followed from the artist formerly known as The Special One.

There were those before today who had not seen enough to convince them that Conte was the right man.

There can be very few now who occupy that position.

This was dedicated to one who could not be here

The tribute to Matthew Harding

When Alan Sugar's Tottenham came to Stamford Bridge 20 years ago this weekend, he remarked: “We never stood a chance.”

In the wake of Matthew Harding's untimely death, the Lilywhites were dispatched 3-1, with the home crowd singing the name of their departed folk hero.

Two decades on, and Harding's presence was felt acutely: not least when his now grown children paraded around the pitch at half time.

Conte made this win, but the crowd also played their part: reminding the players just what Harding had done for this club, and how much he was missed.

Truly, United never stood a chance.

Lucky Luiz

We were warned there would be these moments when he came back...

When David Luiz clattered into the knee of Marouane Fellaini, not long before the break, ref Martin Atkinson reached for his pocket.

In a first half where the official got things largely right, even most of a blue persuasion would perhaps agree he got the colour of card wrong.

It was probably the only bone of contention the United manager could possibly have taken away from this game.

This time Luiz was lucky. Next time he should avoid giving referees those decisions to make.

Crisis? What crisis?

Three games ago there were those questioning Conte's long term employment prospects.

After a run of cash, two bookies closed bets on him to be the next Premier League boss to be fired.

Now his side are fourth in the table, one point off the top spot.

Not a goal has been conceded since Conte switched his side to three at the back.

Victor Moses and Marcos Alonso look born to play as wing backs; N'Golo Kante looks three times the player Paul Pogba is – having only cost a third of the cash.

His position doesn't look quite so shaky any more.

But, keep those superlatives on hold for now...

N'Golo Kante celebrates

Chelsea have grown in strength and posture since Conte's arrival.

His 'Plan A' is coming together, and he could not have picked a better moment for his side to fire on all cylinders.

But there will be questions again about the strength of opposition here: United looked casual, disorganised and uncommitted at times.

In fact, they looked a bit like a few of the worst performances Chelsea put in during the last weeks of Mourinho 2.0.

Chelsea need to keep on improving: because Arsenal, Liverpool and Manchester City – for now all still above them in the table – will prove far tougher opponents, come the day.
