What this game lacks in excitement, it certainly makes up in competitiveness. It has been an even opening quarter, with the Championship visitors creating the best chance of the game so far through bulky striker Jay-Roy Grot.
Arsenal 0-0 Norwich
Olivier Giroud down in the box. The French striker feels he has been hauled down by a visiting defender but the referee does not agree.
Play on.

These three could tear you apart.
It is a quick, pacey pass from Ander Herrera , a lovely deft flick from Marcus Rashford and Jesse Lingard looked very assured in front of goal with that strong side-foot shot into the bottom corner.
Jesse Lingard
Coolly done.
United slice open the Swansea defence, allowing Jesse Lingard to run through on goal.
The Manchester United forward races into the box, opens up his body and calmly rolls the ball home.

It's been coming!
Palace make their dominance count as Ruben Loftus-Cheek feeds Bakary Sako and he fires past Luke Steele.
Upset? Nothing to see here right now.

Rob Holding, from a couple of yards, has to score??
No.
His point-blank header is brilliantly saved by Norwich goalkeeper Angus Gunn.
His dad Bryan would have been happy with that one.
Bournemouth 0-0 Middlesbrough
A lucky let-off for Boro.
The away side fail to clear a ball and the returning Callum Wilson drills wide of goal.

Poor Roy Hodgson.
Crystal Palace's former England boss is reminded of the summer of 2016 when Bristol City's Hordur Magnusson’s long throw is greeted with an Icelandic hand clap by home fans.
Magnusson was an unused substitute when Iceland beat Hodgson's England 2-1.

Extra-time and penalties if scores are level at full-time.
Let's hope we are not in for a long night.
Zero goals so far.
Man City 0-0 Wolves
And the last game of the night is off and running in Manchester.

There have been a lot of backwards and square passes from the visitors. I am struggling to see the midfielders in this Manchester United side who will get their heads up and play the probing, penetrating pass.
There is pace up front with Marcus Rashford and Anthony Martial, they just need to feed it.
Leicester 0-0 Leeds
Ooh, it's promotion-chasing Leeds who carve out the first chance of the game.
It is a swift move down the right and the ball eventually reaches Jay-Roy Grot, whose low shot is pushed away by Leicester goalkeeper Ben Hamer.

Cracking atmosphere at Ashton Gate. The home fans have come to witness an upset but they've seen little from their side so far.
Palace have already hit the bar while Bristol City keeper Luke Steele is called into action to keep out Bakary Sako.
Swansea 0-0 Man Utd
Manchester United boss Jose Mourinho was not happy with midfielder Ander Herrera's comments at the Huddersfield defeat.
It looks like the Spaniard is getting another earful from his boss, who has jumped out of his seat to bark out instructions to his player.

There aren't many empty seats at the Liberty Stadium and, although they're outnumbered, it's the travelling Manchester United fans making all the noise.
Their much-changed team have started impressively, appearing to respond well to Jose Mourinho's criticism of their attitude following their first Premier League defeat of the season at Huddersfield on Saturday.

Arsenal 0-0 Norwich
Little action to speak of from Emirates Stadium just yet.
Norwich have not worked Arsenal debutant Matt Macey so far.
A comfortable start for the Gunners goalie.

So close Lee Chung-yong!
Thunderbolt volley which rattles the bar.
Palace have started well.
