Manchester United - Liverpool: as it happened, goals and reaction
A late Zlatan Ibrahimovic header secured a 1-1 draw for Jose Mourinho and his United side at Old Trafford cancelling out James Milner's first half penalty.
Paul Pogba stood to be United's fall guy at Old Trafford after conceding a soft first-half penalty for handball, which James Milner converted, only for Ibrahimovic to save his blushes.
Ibrahimovic's 19th goal of the season extended United's unbeaten league run to seven games, but after winning the previous six, momentum has been lost.
Jose Mourinho's side remain sixth, four points off the Champions League places, while Liverpool rose one place to third, seven points below leaders Chelsea and beneath Tottenham Hotspur on goal difference.
After draws against Sunderland and Plymouth Argyle and a defeat at Southampton, Liverpool have gone four games without victory at the start of a calendar year for the first time since 1993.
But with United five points below them, Jurgen Klopp's men remain the more likely champions.
An abdominal injury to Nathaniel Clyne saw Liverpool's 18-year-old right-back Trent Alexander-Arnold given a full league debut and he had the onerous task of handling the livewire Anthony Martial.
Martial scored a memorable goal against Liverpool on his United debut last season and he fashioned the first opening with a deep cross for the leaping Ibrahimovic, who could only volley wide.
Ibrahimovic gave the visiting fans a heart-in-mouth moment when he chased down Dejan Lovren's weak back-pass, with Simon Mignolet's clearance striking him and looping onto the roof of the net.
United appeared to be taking control and in the 19th minute Henrikh Mkhitaryan bisected the Liverpool defence with a neatly judged pass for Pogba, only for the Frenchman to scuff wide with his left foot.
Liverpool's play had been more conspicuous for misplaced passes than anything else, but errors from Phil Jones and Pogba enabled them to take the lead in the 27th minute.
Jones's heavy touch allowed Roberto Firmino to rob him on the edge of the box, obliging Marcos Rojo to tidy up at the expense of a corner.
Pogba inexplicably leapt with his hands above his head as he defended Milner's set-piece and the Liverpool number seven tucked the ensuing spot-kick past David de Gea for his sixth penalty of the season.
United twice threatened an equaliser before half-time, Ibrahimovic blasting a free-kick towards the bottom-left corner and Mkhitaryan taking aim from Ander Herrera's pass, but Mignolet saved twice.
Mourinho took remedial action at the interval, sending on Wayne Rooney for his 450th league appearance and withdrawing Michael Carrick, with Herrera dropping into the holding role.
United spurned a great chance to equalise when, having robbed Alexander-Arnold on halfway, Martial sprinted into the box to meet Mkhitaryan's low cross, only to miscue his attempt at a back-heel.
But with Carrick off, United's back four was exposed to counter-attacks.
Divock Origi saw a shot deflected wide, a missed header by Jones allowed substitute Philippe Coutinho to slip in Firmino, obliging De Gea to block, and Georginio Wijnaldum headed Emre Can's cross over.
It was left to Ibrahimovic to ride to United's rescue, the Swede steering a fine header over Mignolet from Antonio Valencia's cross after Marouane Fellaini's header came back off the post.
The noise that Mourinho had called for after United's mid-week League Cup semi-final first-leg win over Hull City duly arrived, but Liverpool withstood the crescendo.
Min 94 | That's it, final whistle at Old Trafford. Points shared.
Min 94 | Into the final minute as United press on. Great last 15 minutes of football at Old Trafford.
Min 92 | 4 minutes of time to be added
Min 91 | Herrera pulls Firminho's shirt and is carded, the Brazilian retaliates by slapping the Basque player and is carded too for his action.
Min 90 | Mourinho bellows instructions at his side with the game into the last minute

Min 84 | The ball ricochets off the bar from a Fellaini header, the ball is fed back into the danger area from Valencia and Ibrahimovic glances the ball home with a header.
Min 84 | Ibra heads home ....Goooooolllll
Min 82 | Rooney almost bags goal 250 but Mingolet saves well. The linesman had his flag up so the goal would not have stood.
Min 81 | If anything Liverpool look like the likelier side to score next.
Min 79 | Time running out for United as we head into the final ten. The Red Devils lacking any creativity and the wall of lime green stands strong.
Min 76 | Wijnaldum latches onto a great cross only for Dutch player to fire the header over the bar. Fellaini on for Darmian.

Change for Liverpool: Off Origo, on Coutinho.
Min 58 | Liverpool dealing well with the added United tempo and apart from the Mkhitaryan effort nothing to trouble Mingolet in the visitors goal. Juan mata to make an appearance.
Min 55 | Far more urgency surrounding United now and the home support doing their bit to rally the side after a very quiet first 45'.
Min 54 | Mkhitaryan through on goal at an acute angle and completely screws his shot wide when hitting the target would have been easier. A let-off for the away side there.

HT analysis: Tonight's game is better than when both sides last met at Anfield but is far from a classic. The men in lime green have shaded proceedings and are deservedly ahead after a unfortunate handball from Pogba which was well spotted by referee Michael Oliver. James Millner dispatched the spot kick and apart from a Mkhitaryan one on one and an Ibra free kick , United have rarely threatened the Liverpool goal.
That's it, whistle blows for the break at Old Trafford.
Min 45 | Last minute as Mou makes his way to the dressing room.
Min 43 | More pressure from the away side as a lofted cross hits the bar and earns the visitors a corner kick. The scoreline is a fair reflection of what we've seen in the first half.
Min 41 | Mkhitaryan breaks through, one on one with Mingolet and fires his shot straight at the Liverpool keeper. Decent half from the former Dortmund player.

Min 32 | Herrera tripped on the edge of the area and United awarded a dangerous free kick.
Min 31 | Lovren booked, first caution of the evening
A brave call from match official Michael Oliver as he spots Pogba clearing the ball with his arm. Calm finish from Millner to see the visitors take the lead.

Min 17 | The Spanish commentary team already making comparisons with the 16/17 season game at Anfield....Lightning can't strike twice surely ?
Min 14 | Ibra goes close as an over-hit cross from Martial is just too far from the Swede to get total contact on the shot and the ball hits the side netting.
Min 13 | Martial tumbles in the Liverpool area and the Old Trafford faithful scream for a penalty but the referee is not impressed.
Min 11 | I had the mis-fortune to cover the game between both sides at Anfield in October and can safely say that it's up there in the top 10 of "worst games of all time" that I've had to witness..tonight must be better ....

After the 0-0 bore draw at Anfield in October hopes are high for a more exciting game this evening at Old Trafford as United (6th) welcome Liverpool (4th) in arguably the biggest game traditionally in English football.
With Manchester City on a wobble following their earlier defeat in Liverpool against the blue side of the city, today's match provides an excellent opportunity for both Jose Mourinho and Jurgen Klopp to make a statement at the summit of the Premier League.
