Conchur Moore: Chelsea defence too lazy and overconfident! Leicester fully deserve that.

Daddy Bella: The best way to play Chelsea as an underdog; Park the bus and catch them on the counter!

Sho: About time someone sucker punched Chelsea for a change.

"The atmosphere inside The King Power Stadium is thunderous. Real belief on and off the pitch. Leicester City have been forced into two crucial substitutions and yet they have stood toe-to-toe with champions-elect Chelsea, worked tirelessly and deserve that lead. The unlikely escape act continues."

Stoke City goalkeeper Asmir Begovic at the King Power Stadium: "It's a dream way to end the half, they'll go into the second half with real confidence. Chelsea controlled the game before the last five minutes of the half but never created any chances. The immobility of Didier Drogba isn't posing any threat, maybe they should consider bringing on Juan Cuadrado for his pace."

Leicester are up to 16th as it stands, above Aston Villa and within a point of Newcastle. What an April they have had!

So far, so good for Rovers in the first leg of their Conference play-off semi-final tie at The New Lawn.

Stoke City goalkeeper Asmir Begovic at the King Power Stadium: "It's a great counter-attack by Leicester. Matty James plays a good ball down the side of the centre-half and it's a very confident finish by Albrighton. It was an unfortunate slip from Azpilicueta, which was a big part of the goal."

Leicester have prevented Chelsea having a shot on target in the first half in both their Premier League games against them this season.

It's also the first time Chelsea have conceded first in the league since December 28 vs Southampton.

Huge reception as the half-time whistle blows. 'We are staying up!' rings out in deafening style. Leicester on it.

A deserved lead for Leicester! Jamie Vardy has the pace to get away down the left after Nemanja Matic gave the ball cheaply away. Vardy cuts the ball back, Cesar Azpilicueta loses his footing on the wet turf and Marc Albrighton keeps his head and sidefoots powerfully home.

James Phteven Lacey: Autonomous. Set out to do what is needed. Nothing fancy, nothing spectacular. Job done.

Kyle Murfet: Dynamic. Mourinho tactically adept, players work together very well.

Paul Harris: Chelsea's season in a word: workmanlike.

It's Chelsea who are hoping for half-time. The champions elect have had six shots on target in the last three-and-a-half games. None so far tonight.

Aston Villa goalkeeper Shay Given on Radio 5 live: "It's a big chance for Leicester. Cambiasso's first touch just took him away from goal."

SCRAMBLE! STRAMASH! BAGATELLE!

What a scramble! Not seen anything like that in the Premier League for many a year. Paul Konchesky lands on a cross at the back post and his shot is well saved by Petr Cech at the base of his post.

Chelsea can't clear though, it's headed back in and Esteban Cambiasso gets there. He could shoot but instead lays it back, but Marc Albrighton's effort is blocked, another swing and a miss, and it's just about hacked out. All over the place.

Not another one! Leo Ulloa now has a problem for Leicester. They've already had two men leave us with an injury, can Ulloa make it a full house? He's being treated and limps gingerly away.

"Some serious micro-management from Leicester City manager Nigel Pearson in his technical area - ordering his players just to move a few yards from where they have taken up position. And judging from what we have seen so far this is a very-well drilled and disciplined Leicester side."

Chxr: Gritty. Took a commanding lead during 1st half of season and grinded out results 2nd half.

Si Hawkes: One word for Chelsea? 'Undeserving'. And not in a good way.

Is there ever a good way of describing someone as 'undeserving', Si?

Danny Drinkwater collects a neat lay-off from Esteban Cambiasso, not much on so he drills a rasper of a drive from 25 yards. It's over but a good effort. Not much rhythm to the game, it's bitty.

Paul Konchesky with a textbook late challenge, you saw it coming a mile off. In the book. He clatters Ramires and Chelsea have a free-kick on the right wing. Cesc Fabregas curls it in but that's easy for Kasper Schmeichel.

Tris Miller: Chelsea's season in one word: zzzzzzzzzzzzzzzzzzzzzzz.

Graeme Hunt: Chelsea in one word. Enviable. Sunderland fan. It figures.

Kumar: Strategic. They attacked when needed to and defended well when they had to.

Operation: Get the ball to Eden Hazard commences. First the Belgian cuts in from the right and almost threads a deft pass through, and then he beats his man easily and forces Wes Morgan to cut out a low cross. From the corner Cesc Fabregas bullets over a cross which just needed a touch.
