Chelsea's struggles have been well documented, but Roberto Martinez's Toffees were 11th in the league table before the start of play.
For the Blues, it was a week in which a 2-2 draw with West Bromwich Albion forced interim boss Guus Hiddink to admit that his side are in a relegation scrap.
That looked like an apt assessment when John Terry bundled into his own net to gift Everton the lead early in the second half.

"John Terry own goal" still my favourite sentence in the English language— Ben McAleer (@BenMcAleer1) January 16, 2016
And the jokes continued to flow when Kevin Mirallas doubled the advantage soon afterwards:

GOAL! It's Chelsea 0-2 Everton... https://t.co/dzsb7oyKPI— Eurosport UK (@Eurosport_UK) January 16, 2016
But Chelsea rallied, and they scored twice in two minutes to square things up after an hour.

This is much more like it. Costa and Fabregas excellent.— TweetChelseaFC (@TweetChelseaFC) January 16, 2016
A game that struggled to capture the imagination in the first half had suddenly exploded into life...
Well that escalated quickly lol #ChelseaEverton— Dalina. (@dalinaberisha) January 16, 2016
I hope Chelsea & Everton play each other forever.— Taffin (@CalvLyfeson) January 16, 2016
...and had one last twist when Ramiro Funes Mori fired Everton back in front in the dying stages.

Perhaps Chelsea deserved it, as they went in search of a late equaliser...
...and up popped John Terry in the ninth minute of stoppage time to spare the Blues' from ridicule for one more week at least (almost).
John Terry goal timed at 97:53. Not sure if it should count as the equaliser or the first goal in the next home game against MUFC on 7 Feb— Sam Wallace (@SamWallaceTel) January 16, 2016

Come the end of the season that could be the point that keeps Chelsea in the Premier League.— Paddy Power (@paddypower) January 16, 2016
11/2011 - John Terry's goal (97:53) was the latest scored in a PL game since Yakubu's for Blackburn v Wigan (98:14) in Nov 2011. Knowledge.— OptaJoe (@OptaJoe) January 16, 2016
There was more than a hint of fortune over Terry's goal:

John Terry’s offside to score Chelsea’s lifeline goal. But, that doesn’t matter, right? There’s an agenda!— Liam (@OffsideLiam) January 16, 2016
Seven minutes of injury-time shown, Terry scores in the eighth extra minute and looked narrowly offside. 3-3— Matt Law (@Matt_Law_DT) January 16, 2016
Anyone getting tired of 3-3 draws?
