"West Ham look a little bit lethargic, and they haven't got the ball into the centre-forward, Andy Carroll today, before bursting up to support him. Whereas Swansea have been everywhere this afternoon, lots of balls into the West Ham box."

The wheels have really come off now for West Ham - Dimitri Payet has just wasted a free kick. Straight into the gloves of Fabianski.

Victor Moses off, Diafra Sakho on. West Ham need him to make an immediate impact.

Michail Antonio has been dreadful defensively but he almost inspires West Ham to get one back here. First he twists and turns Stephen Kingsley inside out and stands up a cross that just eludes Andy Carroll, then the ball comes back to him and he fires a rasping shot into the legs of Lukasz Fabianski.

"Whenever Swansea have had an opportunity to attack they have done. The finish from Ki is incredible.

"When they have attacked they have shown so much quality."

Swansea come back strongly though. Modou Barrow has a shot which fizzes across the face of goal and Winston Reid has to hack it clear.

And they've made a good start. Aaron Cresswell swings a cross in and the ball comes to Victor Moses at the back post. He looks certain to score but the referee blows for a foul on Stephen Kingsley.

Back up and running. West Ham need a big 45 minutes to rescue their Champions League dreams.

So, how did Swansea get back into that match? Well, the play of Ki Sung-yueng had a lot to do with it. As you can see, despite playing on the left of midfield, Ki (number 4) has actually been Swansea's most advanced player in that half. Why? Well, look at where West Ham's right-back is. Yes, that's number 30, Michail Antonio, whose average position has been 10 yards inside the Swansea half.

Let's try and clear up that first Swansea goal for you. Wayne Routledge was (to my eyes at least) ahead of the last West Ham defender when the ball was played in by Kyle Naughton. The question is, did the ball go backwards? This graphic would suggest not...

And that's the interval. A half of two halfs - West Ham were totally on top for 25 minutes but Swansea have been excellent ever since they took the lead.

Against the odds, West Ham's Champions League dream is hanging by a thread.

How has that not gone in? Michail Antonio whips in a superb cross from the right, it finds Andy Carroll at the far post but he hits it across the face of goal, and a prone Manuel Lanzini can't turn it in at the back stick. What a chance for the Hammers.

Ooh, Swansea are looking very dangerous now. With West Ham attacking in numbers, Swansea pinch the ball and Andre Ayew plays a superb pass to set Modou Barrow away. He scuffs his shot wide.

Ayew has taken a whack to the chops here. Ogbonna was the offender. Looking at the replays, I reckon that was accidental, and Michael Oliver agrees - no card.

Geedon Bruce: Could someone find the #bbcfootball, external "experts" who predicted Swansea would be relegated when Guidolin was appointed & bring 'em on the air?

Fair point Geedon, Guidolin has done an absolutely superb job. He's exceeded all expectations at Swansea. But will he be in charge next season?

Lanzini has a shot deflected wide, but the West Ham corner comes to nothing. Some glum faces in the crowd. Defeat here could prove fatal to the Hammers' ambitions of Champions League football.

Goodness me, that could have been 3-0. A low cross is deflected nicely into the path of Cork, he absolutely hammers it but Cresswell does brilliantly to throw his body in the way.

That's ambitious from Ki, firing over from 35 yards. No doubting Swansea's confidence though...

"West Ham started strongly but to be fair to Swansea the two chances they have had they have taken.

"West Ham have not done much wrong but they are 2-0 down."
