That is all for this particular blog, but stay tuned to IBTimes UK for post-match reaction.
Our live text returns on Boxing Day, with an eight-game slate throwing up fixtures including Manchester United vs Sunderland, Arsenal vs West Brom, Chelsea vs Bournemouth and Hull vs Manchester City.
Thanks for joining me. I hope you all have a very merry Christmas.
A dramatic late victory for Liverpool, who replace Manchester City in second and cut the gap to leaders Chelsea to six points ahead of a Boxing Day meeting with Stoke. The Reds entertain City at Anfield on New Year's Eve.
Everton's poor derby record continues, meanwhile. Koeman's side remain ninth and close out 2016 with back-to-back away games against defending champions Leicester and rock-bottom Hull.
Everton 0-1 Liverpool
Liverpool come within a whisker of doubling their advantage, only for a superb last-ditch block from Coleman to deny Firmino.
Unsavoury scenes now with a flare and an intruder on the pitch.
Utter despair from Everton as Liverpool net what will surely prove to be the winning goal in stoppage time.
Clyne passes to substitute Sturridge, who powers past Baines before rolling a low shot against the base of the post.
Never one to lack pace, Mane reacts ahead of Funes Mori, Williams and Joel to tuck home the rebound from close range.
Queue pandemonium in the away end and in the visiting dugout.
Goal: Everton 0-1 Liverpool (Sadio Mane)
Koeman fails to hide his frustration on the touchline after a woeful cross from Barkley ends up in the stands.
It's just not working out for him at the moment.
Joel fails to deal with a Liverpool corner, but Williams is able to clear after a back-post knockdown from Klavan.
We knew that injury to Stekelenburg would result in an extended period of stoppage time. The fourth official signals EIGHT minutes.
Coleman fends off Firmino's latest attempt with a brave block.
Liverpool continue to force the pace before Can slices a pass horribly out of play.
Gana becomes the latest player to be cautioned for steaming into the back of international colleague Mane.
He can expect a ticking off from Senegal head coach Aliou Cisse for that one. The 2017 Africa Cup of Nations gets underway in Gabon on 14 January.
Already lucky not to have been shown a straight red card, Barkley is walking on incredibly thin ice at Goodison.
After Lukaku is whistled for a foul on Lovren, the 23-year-old kicks the ball away before engaging in a war of words with Henderson.
Klopp takes advantage of his bench, sending on returning duo Can and Sturridge. Lallana and Origi make way.
Joel keeps out Firmino's inventive volley with a fine save low to his left.
Origi then gets two chances to cross, but the first is blocked by Baines and the second cleared by Funes Mori. The striker is then penalised for handball.
Almost a chance for Liverpool as Coleman does well to prevent Origi from meeting Mane's deflected low cutback.
Firmino then tries to dispatch Clyne's cross with a difficult bicycle kick but gets it all wrong.
Lots of fouls being committed now that are sapping any rhythm from the game.
Lovren, already on a booking, is draped all over Barkley. The latter's free-kick is nodded straight at Mignolet by Williams.
Koeman goes ahead with a substitution that he apparently had planned even before Stekelenburg's injury. 19-year-old forward Dominic Calvert-Lewin, signed from Sheffield United in August, replaces Valencia for the second game in succession.
Barkley has his name taken for a shocking late challenge on Henderson that could easily have merited a red card.
Lukaku takes exception to Lovren's irate response and that sparks handbags between both sets of players.
Coleman then joins Barkley in the book.
After a lengthy stoppage that will no doubt lead to plenty of injury time, the game restarts.
Stekelenburg, sporting a very pained expression, continues to struggle and Koeman has evidently seen enough.
He finally limps off slowly with help from the Everton physio and Joel comes on in his place. The Spaniard's only previous appearance this season came in October's 2-0 win over West Ham.
A delay now as Stekelenburg, clearly in a considerable deal of pain, limps around trying to shake off that knock.
Joel Robles warms up on the touchline but it looks like the Dutchman will continue for now. Williams takes over goal kick duties for the time being.
Baines and Stekelenburg collide in their attempts to prevent Mane from running on to a lovely backheel pass from Firmino.
The goalkeeper certainly seems to have come off worse from that collision.
Lovren is nutmegged by Lukaku and blatantly blocks off the striker to earn the first yellow card of the evening.
