Until next time...

Tomorrow night, Bristol City host Manchester United and Chelsea face Bournemouth, after which we will find out the draw for the semi-finals

Elsewhere, Manchester City have beaten Leicester City on penalties after a 1-1 draw

We're now into four minutes of added time here at Emirates Stadium

Time for our final change...

Here comes our second change...

Walcott is now playing through the middle, supported by Reiss Nelson and Welbeck

Olivier's involvement is over for tonight - he's given a rousing rendition of his chant as he departs

Uh oh... that doesn't look good

Olivier Giroud was in the process of a bursting run before pulling up with a hamstring problem and falling to the turf

Joe Hart goes into the book for a foul on Danny Welbeck

Francis Coquelin requires medical attention after a foul by Andy Carroll while challenging for the ball

Aaron Cresswell looks to whip the ball inside the far post but he misses the target

Debuchy brings down his man and West Ham have a free-kick just outside of the area and left of goal

The second half has kicked off at Emirates Stadium

Following that slightly delay we're now about to get underway once again...

Update: One of tonight's assistant referees, Stuart Burt, has been taken ill - Chris Kavanagh has stepped up from the role of fourth official to run the line in the second half

At half-time in tonight's other game it is Leicester City 0-1 Manchester City - with the goal coming courtesy of Bernardo Silva

Let's quickly turn our attention back to the first half action before the second half gets underway...

An efficient first half display ends with us one goal to the good... here's a look at what you made of that first half

Deadlock broken! Francis Coquelin with a wonderful floated ball out to Mathieu Debuchy, and his header across the area is flicked home at close range by Danny Welbeck

What a time to score, too...

Kolasinac gets to the byline and hands up a cross for Theo Walcott but the wideman heads wide of Joe Hart's far post

Sead Kolasinac darts infield from the left but lashes a right-footed shot harmlessly high and wide of the goal

Half an hour gone... but there's been nothing by way of goalscoring opportunities just yet

Danny Welbeck wins another corner after seeing his shot deflect behind

A period of pressure ends with us winning a corner - Mohamed Elneny will take

Right, the teams are on their way out and it's almost time for kick-off - COYG!

Per Mertesacker in tonight's matchday programme:

"It is important that we create a lot of chances, that’s first and full most. I think we put that emphasis on it. It’s been an issue in recent weeks and we need to address it and work on it. But that is something which will come back to us, I am pretty sure. Our work has been good on that front in training and in training we are showing it. We go through struggles, but that is not an issue. That is normal throughout a season, but you address it and focus and that is what is important."
