Full-time: Sunderland 1-4 Arsenal
All over at the Stadium of Light! Arsenal were nearly as good as Sunderland were bad.
Anyway, now follow the 3pm kick-offs with us here. Until next time...
Sunderland fans are pouring out of the stadium - and you can't blame them. 4-1 is no giant exaggeration of Arsenal's dominance.
Three minutes of time are being added.
Aaron Ramsey has come on for the Gunners, making his long-awaited return from injury. Arsenal are pushing for more goals, too.
GOAL: Sunderland 1-4 Arsenal (Sanchez)
What. A. Collapse.
Sanchez makes it four for the Gunners, walking the ball into the net after collecting Gibbs' shot that rebounded off the post.
David Moyes looks like a broken man. Any more goals? Let's see...
GOAL: Sunderland 1-3 Arsenal (Giroud)
All over now! Giroud is the hero for the Gunners, heading a looping effort from a corner into the side-netting.
Three points to the Gunners and they will fancy one or two more before leaving the north-east.
GOAL: Sunderland 1-2 Arsenal (Giroud)
Olivier Giroud is Arsenal's supersub! The Frenchman - who has only just come on - converts Kieran Gibbs' cross to give the Gunners the lead, again.
Back to the drawing board for the hosts.
Adnan Januzaj comes on for Steven Pienaar, who is carrying a booking to his name. Meanwhile, Olivier Giroud is coming on for Arsenal.
Cech has been booked for his obvious trip on Duncan Watmore.
GOAL: Sunderland 1-1 Arsenal (Defoe)
Defoe calmly finds the net! Strokes it in the opposite side to Cech and somehow, Sunderland are level.
Arsene Wenger will be livid, especially after his team had a similarly good penalty appeal waved away.
Penalty for Sunderland!
Watmore races through and is tripped by Cech as he goes to round the keeper. A solid decision this time.
Defoe lines it up...
Sanchez is pulled back in the box by Kone and Arsenal look for a penalty. Nothing doing.
On second viewing, that was a certain penalty.
Less than 30 minutes to go at the Stadium of Light now, and I fancy it's time David Moyes rolled the dice. Anichebe is going through some stretches.
Oxlade-Chamberlain drags a decent chance wide of the post with his right foot. Not good, that.
But the longer this game goes on at 1-0, the more the Gunners will start to feel anxious. They should be out of sight by now.
Rodwell commits a foul and then boots the ball away, as they say in the school yard. He's lucky not to be booked for that.
But the pattern of the game has barely changed in this second period. I don't think it's a question of effort, just a distinct lack of quality in the Sunderland ranks. I wonder if we'll see Adnan Januzaj at some stage.
Alexis Sanchez is fouled again and it's fair to say that the silky Chilean is getting pretty sick of the rough treatment he's getting this afternoon. I don't blame him, either.
The crowd at the Stadium of Light are craving a sign, any sign, of encouragement. A shot, a tackle ... anything.
Ready for the second period, then? Sunderland fans will be hoping for much, much better.
No changes at the break - and here we go.
Half-time: Sunderland 0-1 Arsenal
It's about as one-sided a 1-0 lead will ever be, in all honesty. Arsenal have been miles better than the hosts, without creating lots of clear-cut chances. Still, there's more goals to be had in the second half.
Back for more in a bit.
Two minutes of time added at the end of the half. Time for another goal?
The home fans are getting a bit restless. It's understandable, too, because there's no energy or dynamism in their performance.
After a lucky escape earlier, Pienaar is booked for a late tackle. He can't have any complaints - and becomes the third Sunderland player to be cautioned.
To make matters worse, John O'Shea appears to have a hamstring injury and he has been replaced by Papy Djilobodji. The hosts are in danger of coming apart at the seams this afternoon.
Ah, Mesut Ozil has spurned a golden chance for the Gunners! The German latches onto a dinked through pass but cannot quite lob the onrushing Pickford in goal for Sunderland.
Less than ten minutes until the break and still, there's a lack of intensity and belief in the Sunderland performances. They're just standing off Arsenal too much - and are, therefore, being given the runaround.
