Chelsea put their recent defeats behind them as Thiago Silva and Tammy Abraham both scored to see off the Hammers.
The Blues had threatened to fall away following losses at Everton and then Wolves.
Frank Lampard’s side certainly had the look of a side who had been dealt a reality check and West Ham will feel aggrieved by the end scoreline.
They posed the Blues plenty of problems but were on the back foot within 10 minutes as Thiago Silva was allowed a clear run to head home.
West Ham though continued to come as the error-strewn hosts failed to assert their authority on the game.
But Tammy Abraham scored two in the space of three minutes to take the game away from the visitors and ensure that an indifferent performance was not punsihed.
Here are five talking points from the London clash at Stamford Bridge.
Blues bounce back
Had Chelsea lost a third straight league game a blip would’ve threatened to become something more.
As it is they returned to winning ways to stay in touch with the leading pack.
We’ve seen courtesy of Tottenham’s disaster week how quickly things can change.
Every team is admittedly dropping points but two lacklustre games can allow a rival to steal six points on you. Six points that could prove crucial at the end of the season.
Chelsea though were far from their vintage best and certainly showed why they lost twice in four days.
There was a definite nervousness about them when the Hammers were threatening.
Abraham’s quick fire brace then could not have been better timed with the hosts quickly ending any hopes of a comeback.
Moyes will head back across the capital knowing that points were there for the taking.
It always seems to be the way when an up and coming team plays an established one.
The Hammers were not without their opportunities as they found themselves in good positions in the final third.
But the lack of a final ball or a lack of clear thinking undermined their ambition.
It was a similar scenario when they played Manchester United at the London Stadium. A game they lost 3-1
Again they shipped three with the hosts taking advantage of one defensive lapse to take the lead which then left the visitors chasing the game.
West Ham showed enough to prove that they are in the ascendancy they just don’t have the points to back it up.
Lampard on the money
The Blues boss had been keen to quash any talk of the title and based on this performance he is absolutely right.
Lampard knew his side would face “tough moments” and does not believe they are yet the sort of team who can go and string huge winning runs together.
The difficulty is, whilst the west Londoners are a young team still find their way, Roman Abramovich invested heavily in the summer. Some sort of return is expected.
Lampard has emphasised the lack of shared experience within his squad, yes they have winners in their team, but they also have players who don’t yet know that winning feeling.
Liverpool and Manchester City didn’t conquer all in their first years together, there was a pause before they pushed on.
Chelsea look like they need at last another year before they can talk about being champions.
Werner’s woes continue
I can confirm that this Werner we are watching is the same one who played for RB Leipzig last season.
That may be tough to comprehend, I appreciate that.
The German’s scoreless run stretches to nine games with his blank against West Ham and his confidence seems to be low.
Even basic mistakes, like a simple first touch, are beginning to creep in.
A first-half chance went begging, one you feel he would’ve buried were he in full flow, before he smashed the bar late on.
Werner admitted this week that the Premier League is a tougher proposition that he had envisaged, but he retains the faith of his manager.
Lampard spent big on two Germans in the summer, he will be hoping one begins firing sooner rather than later.
Set piece maestros
Chelsea and West Ham have been the two most prolific Premier League teams when it comes to scoring from set pieces.
So it was hardly surprising that Silva got the games opener from a Blues corner.
It isn’t the first time the Brazilian has converted from a set piece, but the fact it came against the Hammers is something of a surprise.
Moyes has got his team incredibly well drilled and perhaps deserves more plaudits than he is getting.
So much so that West Ham hadn’t conceded a single set piece goal before Silva headed home.
Hard to believe in a way given how the Chelsea defender was allowed to waltz into the box unchallenged before scoring – zonal marking not covering itself in glory there.
