Chelsea left it late against Manchester United but they grabbed a point to remain unbeaten under Guus Hiddink.
Jesse Lingard broke the deadlock in the second half with a fine finish that gave Thibaut Courtois no chance.
United looked to be on course for victory until Diego Costa fired in a dramatic equaliser to frustrate the Red Devils.
One worrying note for the Blues was a nasty-looking injury to Kurt Zouma.
The French defender was screaming in pain as he was carried off on a stretcher in the second period.
So after another dramatic day’s football in west London, here’s a look at five things we learned from Chelsea’s 1-1 draw with Manchester United ...
Consistency from Hiddink
Guus Hiddink named the same starting XI for the third straight Premier League game.
Hiddink loves a bit of consistency with his selections and seems to trust certain players more than others.
John Mikel Obi seems to be the first name on the team-sheet these days, despite the Blues midfield lacking in creativity with the Nigerian playing alongside Nemanja Matic.
Eden Hazard injected life into an otherwise dull midweek draw at Watford after coming off the bench but found himself among the substitutes again for the visit of the Red Devils.
Mata still adored
This was John Terry’s first appearance at Stamford Bridge since announcing he is set to leave Chelsea in the summer.
Of course, as expected, there was a big ovation for the captain when his name was read out of the PA system before kick-off.
But he wasn’t the only one feeling the love from the west London crowd as a returning hero was given a warm reception.
Juan Mata, who was player of the season for the Blues before falling out of favour under Jose Mourinho, got a huge round of applause too.
Chelsea fans haven’t forgotten the sterling service the little Spaniard gave to the club as he helped end the wait for a Champions League triumph.
Concern for Zouma
Zouma could struggle to play again this season if scans show ligament damage for the Frenchman after a heavy fall in the second half.
The enthusiastic centre-back rose acrobatically to clear a loose ball near the halfway line but landed in a heap on the turf.
Replays showed his leg buckled under the weight of the fall and the Blues star was left screaming in pain as team-mates immediately signalled to the bench.
Gary Cahill, in front of watching England manager Roy Hodgson deputised at the back and will now have the chance to stake a claim for a spot at Euro 2016.
The knock-on effect might also be that we see more of January recruit Matt Miazga than Hiddink had planned.
Brilliance from Courtois
Petr Cech’s departure left some Blues fans disappointed in the summer but Courtois is the future.
The Belgian was in superb form to keep Manchester United at bay as he saved spectacularly from Anthony Martial and Wayne Rooney.
There was nothing he could do prevent Lingard’s opener though as the forward was allowed time and space to turn before finding the top corner.
United keeper David De Gea also made some eye-catching stops at the other end, notably from Diego Costa, as both custodians proved their worth.
These remain the two best keepers in the Premier League.
Costa needs some help
Costa has been in fine form since Hiddink took over from Mourinho but Chelsea can’t solely rely on the fiery Spaniard.
He cut a frustrated figure under Mourinho but has looked revitalised under the Dutchman, scoring freely and he was the main man again at the death today.
Alexandre Pato has been recruited by the Blues to try and ease the burden but he wasn’t even fit enough for a place on the bench again today.
Hiddink has said he is still in a “pre-season” having not played since November. When will he finally be deemed ready?
