Arsene has a point... but Chelsea don't usually lose matches like that, do they? Anyway, credit to Swansea. That's a decent three points. I'm off now, but stay tuned to the BBC Sport website for plenty more football and, I suspect, the odd bit of KP. Thanks for all your contributions. Night!
- Gomis heads in late Swansea winner
- Swansea complete double over Arsenal
- Arsenal miss chance to close gap on Man City
Arsenal manager Arsene Wenger, speaking to Sky Sports: "We were a bit unlucky with the goal. There are a lot of positives. This kind of game you play 20 times and win 19 times.
"In patches our domination was top quality. You have to learn from defeat and we take encouragement from a defeat like that. Swansea deserve credit for their defensive display but they probably had the fewest passes in our half of any team here this season."
The player to cover the most ground tonight? Gylfi Sigurdsson. The Icelandic playmaker was in a more withdrawn role too. That's a great testament to his manager.
Scorrick: Who has the best return on investment this season? Spurs on 58 points or Swansea on 56?
Abdul Said: Maybe Arsene should not have substituted Francis Coquelin, he is probably the best player to protect his back four.
Sule Sadiq: I've lost all respect for Garry Monk. Swansea parked the bus. This is worse than the train robbery.
Swansea manager Garry Monk, speaking to Sky Sports: "We worked all week on our plan. The players were magnificent and carried it out to the letter.
"I've tried to make the team adaptable. There's no one way to play - as a team you have to be able to adapt and today was a perfect example of that.
"We didn't have a fit striker to choose from the start but I knew if it was tight in the last 20 minutes we could push for a winner."
On the prospect of qualifying for the Europa League: "What will be will be? I don't focus on that. Why shouldn't we push for that? Today showed what we're about and we'll see where the last two games take us."
Remember, Swansea sold Wilfried Bony to Manchester City in January. Since he was sold, Swansea have won eight Premier League games, drawn three and lost five. Not a bad return.
Big, breaking news from the world of cricket...
Our colleagues at Test Match Specialhave tweeted: "We understand that Kevin Pietersen has been told this evening that he won't be picked to play for England again."
More to follow on the BBC Sport website.
We asked you to vote on who will win the Premier League next season. Lots of you got involved... and here are the results. Not many backing City or Liverpool.
Sixteen minutes on the pitch, three touches, one goal.
I should also point out that Swansea completed a league double against Arsenal for the first time since the 1981-82 season. Those were the days of Robbie James, Leighton James and Bob Latchford.
To be fair to Arsenal, that Swansea goal came from nowhere and they ran into an inspired Fabianski in the second half. Seventeen of their 22 shots came in the second half.
"There's a really good turnout from the Swansea fans tonight and they have seen history. It's been a feature of their season. Everything has gone to plan. They have been really impressive."
So... Arsenal miss the chance to go level with Manchester City in second and Swansea close in on Southampton. What a season the boys from south Wales are having.
The only other two teams to do the double over Arsenal in the Premier League era? West Ham (2006-07) and Chelsea (2009-10).
The Emirates is emptying quickly as Arsenal lump it forward... and there it is, Swansea have done it. Three points and the double over Arsenal. Maybe they won't be winning the league next season after all.
Arsenal are getting desperate now and a low cross into the box is cut out by Fabianski. Swansea holding on well... another Aaron Ramsey shot being charged down.
Phil Neville did say last week that Arsenal are a goalkeeper short of a title-winning team. Would David De Gea or Thibaut Courtois have kept that out? It wasn't the firmest header in the world. Four minutes of injury time.
Peter Collins: Ospina should, really should have been saving that. It wasn't that difficult for him. He's better than that.
A couple of you pointed out my slip of the keyboard earlier. I referred to Swansea manager 'Garry Mink'. My bad... the man who is on his way to masterminding a double over Arsenal is anything but a "semiaquatic, carnivorous mammal of the Mustelidae family". I got that last bit off the internet!
Game over at the County Ground - and Swindon come out on top after the highest-scoring match in play-off history. It finishes 5-5 on aggregate, with Swindon edging Sheffield United 7-6 on aggregate.
They'll meet Preston in the final for a place in the Championship on 24 May.
"It's definitely a goal, clearly over the line. The ref is holding is hands out as if to say 'there's nothing I can do about it'. Ospina palmed it out, but it was too late."
Smash and grab. Swansea catch Arsenal cold, with Jefferson Montero putting in a cross from the left and Bafetimbi Gomis heads home. Or does he? Yes... it's a goal. The linesman's arm is buzzing. David Ospina's attempt to scoop the ball from behind the line are in vain.
Arsenal 0 Swansea/Technology 1.
Neil Taylor has been Swansea's weak link tonight, with all of Arsenal's best play coming down the right. The full-back almost gives the ball away to Jack Wilshere in the middle of the park but recovers just in time.
UNBELIEVABLE drama in the League One play-offs. Since we last mentioned it there have been three more goals. Sheffield United have just scored twice in a couple of minutes to make it 5-5 on the night against Swindon, meaning the Blades trail 7-6 on aggregate. One more goal takes it to extra time.
Brilliant, brilliant game. Seven minutes of added time being played -follow it here.
"He won't get a better chance all season. Somehow he has played it straight at the goalkeeper."
How has he not scored there? Or there? First Fabianski denies Alexis Sanchez from close range and then Santi Cazorla in similar territory. Swansea bring on Mo Barrow.
A shot from Aaron Ramsey, but he's stretching and it's easily dealt with by the keeper.
Everyone is penned back for Swansea now as Arsenal begin to apply the squeeze. Arsene Wenger is getting agitated on the touchline and Bafetimbi Gomis is brought on for Swansea, in place of Ki Sung-yueng. A positive change from Garry Monk.
Matt Wortley: Wilshere & Walcott on...the Arsenal medics are warming up.
Theo Walcott from six yards out... a stabbed shot... at the keeper. Groans.
Jack Wilshere is throwing himself into everything. I suspect he's one of those people who gets competitive playing Monopoly. He's added to Arsenal's intensity though. Got to be a breakthrough soon.
Jack Wilshere... how good is he? I rate him, I rate him highly. But I read the papers and they say Manchester City are interested and could pay £30m. Is he worth that much? Either way, he's straight into the action here and drives down the Swansea left before firing into the side-netting. Arsenal have also brought on Theo Walcott.
Eddie: Could do with a Flappyhandski moment here from Lukasz to grab all 3 pts. He owes us at least that much.
Time for Jack Wilshere. Francis Coquelin gets the hook.
"That was a loose bit of defending from Swansea. Cazorla was given far too much time, but it was Fabianski to the rescue."
Santi Cazorla is a magician. He's got three players around him in a space the size of a phone box (kids, ask your Mum and Dad) and he still manages to get a shot away. Straight at the keeper though.
A goal is coming. Trust me. Aaron Ramsey finds the side-netting this time. End to end.
Time for a change. Angel Rangel is off and Jazz Richards is his replacement. Good name.
A low shot from Olivier Giroud from just inside the area is straight at the keeper, and the first attempt on target for the Gunners.
Thomas Mottershead: Arsenal play some nice passing football but they're too slow in the process! Gotta pick up the pace!
Sachin Sadier: Arsenal are finally showing showing signs of life, driving forward attacking the goal.
