Leicester City 0-0 Chelsea
Place your bets.
Jamie Vardy in a foot race with Willy Caballero as the pair chase Vicente Iborra's pass from the opposite end.
The Chelsea goalkeeper actually manages to get there first.
And puffs his cheeks in relief after laying it off to Tiemoue Bakayoko.

This match is crying out for moment of magic from somebody... but there are plenty of players on the pitch capable of doing that.
Leicester City 0-0 Chelsea
Alvaro Morata is getting hot under the collar.
Irritated by a muscular challenge from Wes Morgan and then floored by Wilfred Ndidi's bustle, the Chelsea striker springs to his feet and hurtles into the next challenge.
Free-kick Leicester.
Maybe he could do with a little more fire in the belly though...
He is no Didier Drogba or Diego Costa at the moment.
Leicester City 0-0 Chelsea
Alvaro Morata manages to spin around Harry Maguire - on a yellow card - and to the byline.
There is nobody in a Chelsea shirt in the box, so the former Real Madrid man tries an ambitious scooped effort from a vice-tight angle.
Into the wrong side of the side-netting.

Lee: Morata should have done better with that chance!!
James: Mahrez controlling the ball is a footballing joy to watch.
Leicester City 0-0 Chelsea
The boos when N'Golo Kante touches the ball have died down. Not surprising really - he's having too many...
The Chelsea midfielder has had 32 touches - more than any other player on the pitch.
Seems those Leicester fans treating him as the pantomime villain are bored of booing now...

Chelsea striker Alvaro Morata is being roughed up by Leicester City's defence and Harry Maguire has picked up a booking.
Leicester's fans are irate that Morata is spending so much time on the deck and it will be interesting to see how he responds with the likes of Maguire and Wes Morgan determined to make it a physical battle.

We were talking earlier about the wing-back areas. Riyad Mahrez leaves Marcos Alonso, and Danny Simpson can't go out, so Alonso has oceans of room.
Alvaro Morata didn't get a connection. He will be disappointed because of the time he had. It was a chance.
Leicester City 0-0 Chelsea
That was a chance.
Alvaro Morata is picked out by a cross from the left.
His first touch is instant control, his second is a crisp shot, but, from 18 yards, it is straight into the gloves of Kasper Schmieichel in the Leicester goal.

Lee: Kasper Schmeichel hasn't had to much so far!
AJ: Way too many orange boots on show here. What happened to good old black boots!

Nothing to trouble Kasper Schmeichel so far. Leicester's back four been comfortable and have narrowed up really quickly, which you have to do against Chelsea.
Then they've relied on Albrighton and Mahrez helping out their full-backs when the Chelsea wing-backs fly forward.
So far so good for Leicester defensively.
Leicester City 0-0 Chelsea
Third time is the clincher for referee Craig Pawson.
Again it is Alvaro Morata picked out for the tough stuff by the Leicester defence.
Harry Maguire is booked for this bit of roughhouse naughtiness though.
His expression is still set to butter-wouldn't-melt saintliness.
Leicester City 0-0 Chelsea
Harry Maguire's turn.
The other Leicester centre-back bundles into the back of Alvaro Morata to send him tumbling.
Leicester City 0-0 Chelsea
Look up 'reducer' in your big book of football cliches and you get a picture of Wes Morgan's challenge on Alvaro Morata.
The Leicester captain chases Morata back into his own half and clatters into the Spaniard to ensure that his second touch of the match is not a comfortable one.
No card. Just a free-kick.
Leicester City 0-0 Chelsea
It's fair to say Alvaro Morata hasn't really got into the game yet...
Only the one touch for the Chelsea striker in the opening 20 minutes. The ballboy behind the goal has had more.
Leicester City 0-0 Chelsea
Wilfried Ndidi is urged to shoot as he controls the ball 25 yards out.
He doesn't need asking twice.
A big backlift, an elegant strike with a hint of outside-of-the-boot curl, but Willy Caballero is down well to save off the slick turf.
Leicester City 0-0 Chelsea
"Get at them out wide," is a paraphrase of what Antonio Conte must have said in his pre-match teamtalk.
Certainly judging by the graphic of Chelsea's attacking third.
Almost 85% of their attacks have come down the flanks, with wing-backs Marcos Alonso and Victor Moses particularly prominent.
Leicester City 0-0 Chelsea
Better from Chelsea.
Eden Hazard slides a pass between the ribs of the Leicester defence for Alvaro Morata.
The Spaniard gets to the byeline and cuts back towards Hazard, but the ball is too sharp and gets away from his first touch.

Gavin: Bakayoko is already having a shocker. Can't say I'm shocked
Sam: Watching Bakayoko back in the Chelsea team and just can't see what he adds - he gives the ball away, looks slow physically and mentally... not good enough honestly.
