That second has now been given as a Jack Cork own goal, not to Alex Iwobi as first thought.

Backs to the walls now for Swansea.

Alexis Sanchez plays a superb throughball to Aaron Ramsey, who turns and shoots from six yards out, but the effort is well saved by Lukasz Fabianski.

Arsenal looking to put this game to bed now.

Alexis Sanchez and Alex Iwobi both have shots from inside the area in quick succession, but the efforts are blocked by strong Swansea defending.

That is the sort of commitment Paul Clement will need throughout the remainder of the season...assuming he lasts until then.

A smart move started by Alexis Sanchez, who turned beautifully on the halfway line. He feeds the ball out wide to Alex Iwobi, but his ball into the box is cut out by a Swansea man.

Olivier Giroud was sniffing another just in behind there.

One of Paul Clement’s priorities is to improve the Swans’ defence – the most porous in the Premier League – and the former Bayern Munich assistant manager will have been encouraged by the way his players initially shackled Arsenal with their high pressing.

But the home side were a little slack for Olivier Giroud's goal, undoing their early good work.

The home fans seem encouraged, judging by their cries of 'Paul Clement's Barmy Army'.

Olivier Giroud looks like he has made a recovery and is back out in the second half. I am told it is a toe injury he is hobbling around with.

Nathan Dyer, not Lloyd Dyer.

Nathan Dyer, not Lloyd Dyer.

He only won the Premier League title last season. Thanks to Sam Walsh for pointing that out on Twitter.

Anyway, back under way at the Liberty Stadium.

Swansea have had their moments in this game but, other than that penalty shout, not many of them have come in the Arsenal area - they only managed four touches in there in the first 45 minutes.

All five of the Swans' shots have come from outside the box and, tellingly, none of them have come from their main striker Fernando Llorente.

Only one of those five efforts have been on target, too. Kyle Naughton's low drive that almost sneaked past Petr Cech, shown by the green arrow above. The red arrows are off target, the yellow circle is an effort that was blocked.

So, signs of improvement from the Swans - but more needed from them up front in the second half.

Opinions all across the board for the non-penalty decision from Mike Jones on 44 minutes...

C M: Booking for diving for that, looks an awful decision

Pascal Van Der Kamp: Top decision by Mike Jones, Ki Sung-Yueng looked for that

David P H Thomas: Being a ref in the Prem really is impossible

Olivier Giroud's goal the difference at the interval.

Time for Paul Clement to earn his crust.

Arsenal have been sloppy in possession today and Mesut Ozil gives the ball away in his own half after trying a cross-field pass.

It is picked up by Nathan Dyer, who makes his way towards the edge of the area, but then smashes a drive over the crossbar.

Wasted.

Penalty?? The crowd think it is, but then again, they usually do.

Swansea midfielder Ki Sung-yueng does down in the box under a Laurent Koscielny challenge and Mike Jones blows his whistle.

He strides into the area...

...and books the South Korean for simulation.

BRILLIANT decision.

Ki left a trailing leg on Koscielny, but Jones was not buying it. Well done ref.

Olivier Giroud signalling the 'roly poly' to the bench.

He wants to come off.

Not sure what the injury is.

A reminder that Swansea have lost 12 games when they have gone behind this season.

Paul Clement has plenty of work to do if he wants his side to turn this match around.

Referee Mike Jones has a word with Swansea's Nathan Dyer after a late challenge through the back of Nacho Monreal.

The Arsenal man is not happy, a naughty one from Dyer.

What's the weather like where you are? Let me know using #bbcfootball, external if you want.

Just over half an hour gone.

Arsenal fans, if you're thinking of staying up to watch the highlights of this on Match of the Day tonight, don't bother. Make other plans.
