Image source, PAA deafening roar has just swept around The King Power Stadium as Chelsea were once more pressed into submission by Leicester City.
Team and players are at one here, with "The Tinkerman" Claudio Ranieri urging his men on from the technical area. What a story this is turning into.

Leicester 2-0 Chelsea
The away end remains defiant in the face of yet more adversity. Chelsea fans are chanting loudly as their team try to get behind Leicester's defence. Robert Huth boots a Willian cross clear.

"Am I allowed an opinion on this one? Will Chelsea go with three centre halves, or will Nemanja Matic drop into the back four?
"It looks like they will play with three centre-halves with Branislav Ivanovic, Kurt Zouma and Cesar Azpilicueta."

"That was a good foul for Robert Huth to commit. Diego Costa was away, and to be fair to the Chelsea striker he didn't react."

What response have Chelsea got? A positive one to be fair. Diego Costa chased down the right channel, gets smacked down by Robert Huth. Booking.

Riyad Mahrez
Image source, ReutersTop drawer! Leicester double their lead through some more Riyad Mahrez magic. Up there for thinking, down there for dancing. The Algerian international shows quicker feet than Danny Zuko, waltzing past Cesar Azpilicueta before bending in a delicious curler from the right side of the Chelsea box.
Leicester 1-0 Chelsea

"Diego Costa rolled around and then got straight up to his feet and he was head to head with Jamie Vardy. Mark Clattenburg was right to book Vardy but the reaction of Costa, he was lucky there.
"The Chelsea striker should show more of that sort of energy in the final third."
Leicester 1-0 Chelsea
Leicester are 45 minutes away from their sixth win in seven league matches - and claiming top spot in the Premier League. The home side restart the action.

The players are heading back out of the tunnel - Leicester's players with a spring in their step.

Leicester's lead is fully deserved - sharper and more fluent than the fading champions.
Where is the spark for Chelsea? Diego Costa has looked clumsy and off the pace while Eden Hazard is off injured - so it has been left to Willian to fight a lone battle.
Once again Jose Mourinho is left with the task of lifting his players, How has it come to this for a team that was so impressive last season?
Leicester 1-0 Chelsea
Here's how that lethal Mahrez and Vardy combination as proved fruitful for Leicester tonight. Mahrez (26) cross + Jamie Vardy (9) volley = goal. It's the perfect equation for the Foxes.

"Whether it be counter attacking, pressing, Leicester always seem to make the right decision, and they do it so quickly. The partnership between Jamie Vardy and Riyad Mahrez is great.
"Top players take chances but the Chelsea team look like they are scared to make a mistake."
