Chelsea cruised to victory over Everton to well and truly put their early season woes behind them.
Alvaro Morata's header to Cesc Fabregas allowed his compatriot to open the scoring in the first-half, before the game was all but sealed by Morata before the half-time whistle.
Once again with his head, Morata was perfectly placed in the box to guide Cesar Azpilicueta's header home.
The win will delight Chelsea boss Antonio Conte on their first return to Stamford Bridge since they were humiliated by Burnley there on the opening day of the season.
Our man Adrian Kajumba was at the Bridge watching all the action...
1. Morata proving to be a shrewd addition
Alvaro Morata will lead the line for Chelsea in a very different way but they should be no less effective.
He doesn't have the same forceful personality that Costa had – for good or bad – that let you know he was always on the pitch.
In fact Morata can go unnoticed for periods. He is not one for getting stuck in to physical stuff and failed to provide the threat in behind that his teammates wanted at times against Everton.
But with his runs right across the frontline, movement, intelligence, link-up play and selflessness he looks capable of helping Chelsea remain just as effective up top.
Another goal and assist for Cesc Fabregas' opener will do his confidence no harm too.
2. Gueye was lucky not to see red
If it wasn't for Miguel Britos's assault on Anthony Knockaert in Watford's goalless draw with Brighton Idrissa Gueye would have been responsible for the worst tackle of the weekend.
He caught Cesc Fabregas in the ninth minute with a shin-high, studs first challenge.
It looked bad at first and even worse on the replays. Like Britos, Gueye's reaction when he was being disciplined was bafflingly one of surprise.
He should have been relieved not to see red.
3. There's a gap between Everton and the rest
This, much more than Monday's draw at Manchester City, underlined the gap Everton are trying to make up.
Everton were impressive at the Etihad but outclassed all over the pitch at Stamford Bridge yesterday, perhaps due to
Ronald Koeman has spent over £100m to try and improve on Everton's seventh placed finish last season.
But there are six strong sides ahead of them, topped by Chelsea. And this game highlighted just how hard it will be to catch them.
4. Fabregas offers reminder of his class
The Spaniard was back in the team after suspension and provided a timely reminder of his class and quality.
Timely because Antonio Conte wants to go shopping before the transfer window closes on Thursday and has midfielders in his sights.
Alex Oxlade-Chamberlain, Danny Drinkwater and Ross Barkley are all among the Blues boss's targets.
But none of them can effortlessly help their team control a game like the classy Fabregas does.
His goal showed his cleverness as he quickly adjusted his feet to steer in Alvaro Morata's header on and then spent the rest of the game keeping Chelsea ticking over in midfield.
5. Rooney looked more like his late United self
Wayne Rooney endured a frustrating afternoon on his first run out since his international retirement.
Eyes were on Rooney following his decision to call time on his England career and allow him to put more into his Everton one though this was not his day.
In fact, this was more like the Rooney we saw in the closing stages of his Manchester United career looking a little off the pace and unable to effect the game.
He spent most of the game arguing with referee Jon Moss and eventually talked himself into trouble when he was booked for dissent.
Meanwhile a scuffed attempted volley that drifted apologetically wide summed up his afternoon going forward.
