Alan Curtis is beaming on the Emirates turf and Ashley Williams applauds the travelling faithful before hugging his coach.
That's that from me, thank you for joining me.

Petr Cech comes up for an Arsenal corner but it is defended and Bafetimbi Gomis shoots from his own half, it won't threaten the empty net.

A cross into the box drifts past everyone and Swansea have a goal kick. Their fans are in fine voice in the corner of this huge stadium.
All the Swansea shirts are behind the ball bar Bafetimbi Gomis who tries to run the ball clear but back come Arsenal...
PENALTY APPEAL

Aaron Ramsey bursts into the box and goes down under the challenge of Ashley Williams, nothing doing. We have five added minutes.

Lukasz Fabianski has the ball in his hands after fielding a tame header. We have two minutes of normal time to go and Swansea look relatively comfortable.
A substitution to waste time now, Angel Rangel for Andre Ayew.

Karly Boy: Wenger is clueless, his substitutions are laughable, bring in Mourinho, anything is better than this feeble capitulation.
Vince: I wonder what lines Wenger will come out with to insult our intelligence this time? 8 million a year...for this?

Arsenal 1-2 Swansea
A win tonight and Arsenal are right in the mix, make no mistake. But a look at their away fixtures does prompt concern. To say there are trick trips is an understatement.

The Gunners venture away from the comfort of Emirates Stadium to face Tottenham, Everton, West Ham, Sunderland and Manchester City.
It looks a tall order. Surely, surely, their title dreams are over now?

There seems to be little belief in this Arsenal side now. They are spluttering towards defeat and Andre Ayew is game for a fight as he draws a foul from Danny Welbeck. What a result this would be for the Welsh side, they'd be six points clear of the drop zone.

So what have Arsenal got? Aaron Ramsey is in the area and finds Olivier Giroud, on to Nacho Monreal who is 14 yards out but lifts the ball over.
Hope for Arsenal

“Not only was Cech at fault but there was no-one marking Williams. You cannot make those mistakes at any level, never mind when you are chasing a title.”
SUBSTITUTION
Arsenal 1-2 Swansea
Theo Walcott in for Alexis Sanchez. Arsenal could be about to lose three straight games for the first time since 2010.
GOAL
Arsenal 1-2 Swansea - Ashley Williams

Gylfi Sigurdsson stands over a free-kick for Swansea in a wide area, in it comes... GOAL. Ashley Williams knows little about it but turns home from a couple of yards.
Petr Cech seemed to miss his punch in the six-yard box and the ball just hit Williams who races away punching the air.

Aaron Ramsey in the Arsenal midfield, wide for Hector Bellering who crosses into the arms of the visiting goalkeeper. Easy. He will take them all night long.

This is only Jay Fulton's third league outing in a Swansea shirt. A big ask.
SUBSTITUTION

Leroy Fer makes way for Jay Fulton in the Swansea midfield.

The stage is set for Alexis Sanchez as he lines up a free-kick in a central position. Here he comes, small deflection... WHACK. Off the bar. That's the second time Arsenal have hit the woodwork.

There are boos, there are hands on heads in the stadium.
As a colleague says, "Arsenal just cannot help themselves". It seems any hope of a first title since 2004 is now gone. Surely it's over?
