What a day for Burnley and what a day for Andre Gray.
Certainly one to remember for him, and one to forget for David Moyes and anyone connected with Sunderland.
Thanks for joining us and bye for now.
And it is all over. Sunderland were absolutely awful, but the day belongs to Burnley and Andre Gray.
He becomes the first Clarets player to score a Premier League hat-trick as they recorded a comfortable victory.
Where do Sunderland go from here? Well, a home game against Liverpool, the top goalscorers in the league, is next up on 2 January.
If the Black Cats defending is anything like today then it will be a long day for Sunderland fans.
No sign of that fightback just yet. Sunderland's Seb Larsson has just had an effort from 20 yards, that went almost the same distance over the top.
Eight minutes left for what would be one of the greatest comebacks all time. Maybe.
Seb Larsson has just wasted a free-kick and Jermain Defoe has had an effort blocked.
Robbie Edwards: I'm slowly losing faith in Sunderland. With no money to spend in January relegation looks a formality now.
Hat-trick hero Andre Gray goes off to a standing ovation from the home fans. He goes off for Sam Vokes.
If Sunderland are to have any chance of staying up then they just have to keep hold of Jermain Defoe.
The striker has just scored his ninth goal of the season, out of Sunderland's Premier League total of 17.
It is a well-crafted goal too as Adnan Januzaj leads the charge forward and dinks in a pass to the back post that evades the head of Ben Mee.
Defoe takes a touch to set himself and shoots from close range past Tom Heaton. The complete lack of any celebration is so telling though.
Johnny Magrinho: Sunderland have been spoiled with Pickford's stoic performances - the next 6-8 weeks without him will be long & unforgiving.
A calm penalty from Ashley Barnes, who rolls the ball into the bottom corner.
That is 4-0 on a hugely embarrassing day for anyone connected with Sunderland.
This could be 4-0. The horrow show for David Moyes continues. It is an awful, clumsy challenge from Seb Larsson which bundles Scott Arfield to the floor in the penalty area.
The referee points to the spot and Ashley Barnes gets ready.
Four years ago Andre Gray was playing in the sixth tier of English football with Hinckley United.
Today he has scored a Premier League hat-trick.
More awful defending from the visitors, who have looked embarrassing at the back since the first-half injury to centre-half Lamine Kone.
This time the ball falls to Burnley's Scott Arfield, unmarked, in the penalty area. He should do more then shoot tamely at Vito Mannone.

Talking about Burnley's second goal.
I think that's the reason Vito Mannone's not still at Arsenal - he can stop a shot but his decision making is awful.
Sunderland's defence hasn't turned up today, you could have driven a double-decker bus through their defence just then.
What a day for Andre Gray. He holds the match ball aloft after grabbing a Premier League hat-trick.
It is more embarrassment for Sunderland. Substitute Steven Pienaar stands on the ball and that allows Burnley to hit what should be a routine ball into the middle of the Sunderland defence.
But Ashley Barnes has time and space to slot in a pass to Gray, who steers his shot past Vito Mannone into the bottom corner.
That is three for Gray, and three points for Burnley.

Why has Vito Mannone come so far out? He made Gray's mind up for him, making it easy for him to skip past him and finish with ease.
This is a huge result for Burnley if it stays the same.
More terrible defending and Andre Gray capitalises for his second goal of the game.
A speculative ball is hit forward and Gray, who holds off a challenge from Papy Dijobodji, gets to the ball before Vito Mannone.
The Italian goalkeeper had sprinted out of his penalty area, but is caught out and Gray takes the ball round Mannone and puts it into an empty net.
What a chance for 2-0. Andre Gray again bursts through the middle of the Sunderland defence and is only denied by an excellent save from Vito Mannone.
The follow-up falls to Ashley Barnes but an excellent block from Papy Dijobodji keeps the ball out of the net. An assistant's flag was then raised when Barnes got the ball, although no-one is too sure why. But it didn't go in anyway so now arguments.
We are back under way.
As expected, Victor Anichebe is not able to play in the second half so Steven Pienaar comes on in his place.
Just the one shot on goal, which went in, and no corners. It might not make the longest of highlights packages on Match of the Day tonight. Still, Burnley fans will not care if it stays like this.
And that is the first half.
This tweet sums up Sunderland's frustrations.
Just when you think it can't get any worse for David Moyes and Sunderland, it does.
Striker Victor Anichebe is trying to track back and catch George Boyd down the left wing before the striker pulls up suddenly with what looks a hamstring injury.
He immediately signals to the bench that he is done. Sunderland do not have a replacement ready so end the half with 10 men. More injury woe for the Black Cats.
It is getting feisty. Burnley's Dean Marney is booked for clattering into Fabio Borini.
It is the classic double combination of toe trodden on and a clash of knees. Ouch.
One booking for each side now.
Sunderland's Billy Jones slides in and catches Stephen Ward. Rash and painful.
Ward needs treatment, while Jones is shown the yellow card. It is a costly booking as Sunderland will now be without the defender for the game against Liverpool on 2 January as that's his fifth booking of the season.
Sunderland have looked a shambles at the back since Lamine Kone went off injured. Burnley's Scott Arfield is allowed to shoot unchallenged from outside the area but the radar is slightly off with the ball narrowly going past the post.
Burnley looking good value for their lead so far.
By the way, that Andre Gray goal came from the first shot on target in the match.
Gray had gone 10 games without a goal but now has two in five days after also getting the winner against Middlesbrough on Boxing Day.
It is nearly 2-0. Another fine delivery from right-back Matt Lowton finds Stephen Ward sliding in at the back post. He can't get a good enough contact on it though and can not direct it goalwards. Unlucky.
Hull City defender on Final Score
A schoolboy error there, both centre-halves going for the same ball. Then the ball comes off John O'Shea and it's an easy finish.
Disaster for Sunderland, and it is all their own doing. John O'Shea and Papy Djilobodji both challenge for the same ball, with it hitting O'Shea's shoulder and bouncing backwards.
The ball falls to Andre Gray who runs through and his shot is too powerful for Vito Mannone and the Clarets lead.
Another moment of worry for David Moyes. Papy Djilobodji is holding his face after an accidental collision. He can continue though.
We said Lamine Kone's injury was one to watch, and it is bad news for Sunderland. He is lying on the ground, holding his hip and shaking his head. He hits the ground in frustration and that is him done for the day.
Kone is meant to be heading off on Africa Cup of Nations duty with Ivory Coast soon, so it could be a double blow for the player.
He is replaced by another potential Afcon player, in the form of Gabon's Dider Ndong.
It means captain John O'Shea, who had started in a holding midfield role, now drops back into the defence.
A half-chance for the hosts as Andre Gray looks to be through on goal but a heavy first touch loses the opportunity with his effort from a tight angle only hitting the side netting.
There is also a painful moment for Sunderland defender Lamine Kone who, in his attempt to block Gray's shot, slides into the advertising hoarding behind the goal.
The big defender can carry on, but he is limping. The last thing David Moyes would want is any more injuries to an already stretched squad. One to monitor.
Another chance for Burnley, but again they do not register a shot on target. Matt Lowton's cross from the right-back position finds Ashley Barnes, but under pressure from a Sunderland defender, he can only head wide of Vito Mannone's goal.
The Italian goalkeeper has only had a couple of Checkatrade Trophy matches since his last Premier League appearance, a 2-1 home loss against Middlesbrough on 21 August.
But with Jordan Pickford out for at least six weeks it is a chance for Mannone to impress.
He has been a spectator so far though. And is again moments later with Andre Gray firing well over.
Best described as scrappy so far. No efforts on target, with neither side being given much time on the ball. Frantic, but lacking quality so far.
Burnley have picked up 20 points this season. Nineteen of them have come at home.
A first sighter for Burnley and it falls to their Boxing Day match-winner Andre Gray. He is just outside the penalty area, but off balance he can only shoot off target. Nothing for either goalkeeper to do so far.
An early chance for the visitors, but it is a disappointing finish from the returning Adnan Januzaj.
The ball falls to him on the edge of the penalty area, in the middle of the goal, but Januzaj balloons it well over the top. Some early 2017 shooting practice needed for the on-loan Manchester United midfielder.
And we are under way. Our referee today is Graham Scott. Let's go.
