The captain converted a brilliant flick – from an offside position – after Ramiro Funes Mori appeared to have won it for the Toffees with a goal in the last minute of normal time
John Terry’s 98th-minute equaliser rescued a point for Chelsea and capped a thrilling and controversial finish to their 3-3 draw against Everton.
Ramiro Funes Mori had put Everton ahead in the 90th minute after the Toffees had blown a two-goal lead but Terry equalised deep into stoppage time from an offside position to preserve Guus Hiddink’s unbeaten start.
The two sides exchanged few chances in the first half but the match burst into life when Terry sent a Leighton Baines cross into his own net shortly after the break.
After Ross Barkley had hit the post, Kevin Mirallas worsened Chelsea’s predicament with a sublime second in the 56th minute at the end of another flowing Everton move.
But Diego Costa – who limped off late on – and Cesc Fabregas scored goals two minutes apart in a rousing comeback before Funes Mori’s brilliant finish in the final minute of normal time.
Not for the first time this season, Roberto Martinez’s side failed to see the game out although they will be angered by the assistant referee’s failure to flag Terry offside.
Hiddink replaced Oscar with Nemanja Matic in his only change from Wednesday’s 2-2 draw with West Brom, a move that offered Fabregas more freedom in midfield.
It almost paid dividends within 16 minutes as the Spaniard slipped the lively Willian in behind the Everton defence with a well-weighted pass, but the Brazilian’s powerful strike was deflected over by Howard.
Everton threatened on the break with Hiddink’s team guilty of giving the ball away cheaply, but it was not until five minutes before the interval that Martinez’s side tested Courtois, who had to dive low to his left to keep Mirallas’ effort out of the bottom-left corner.
The hosts started the second half strongly, but fell behind when Baines’ low cross from the left caught Terry out and the Chelsea captain inadvertently sent the ball into the back of his own net.
Barkley came close to doubling Everton’s advantage shortly after when his near-post effort crashed off the upright, but Mirallas did add a second when he expertly controlled another Baines cross and followed it up by lashing the bouncing ball beyond Courtois.
Chelsea’s response was brilliant, however, and by the 66th minute they had restored parity with two goals in quick succession.
First, Costa capitalised on Phil Jagielka’s indecision to sneak between the centre-back and Howard and the striker then returned the favour for Fabregas, producing a clever backheel to find the Spaniard, whose deflected shot from the edge of the area snuck inside the near post.
Everton looked to have found the winner in the final minute of normal time when Funes Mori hooked Deulofeu’s deep cross into the back of the net.
However, Terry latched onto Oscar’s header inside the box to score a sensational equaliser with 98 minutes the clock despite calls for offside.
