Kouyate heads in from corner after Albrighton's finish for City
Draw leaves West Ham in bottom three
Puel has a win, two draws and loss from his four City games
Cheikhou Kouyate
On the verge of half time.
For once, Manuel Lanzini gets his delivery from the corner spot on, swinging a cross into the six yard box.
Cheikhou Kouyate is the man who nods it towards goal, it comes off the shoulder of Danny Simpson and lands in the net.
West Ham's first goal under the tenure of David Moyes.

Another Marko Arnautovic cross, again headed away by Danny Simpson.
Can West Ham nick one from the corner?
West Ham 0-1 Leicester
This is gorgeous football from Leicester.
Midfielder Vicente Iborra, who stands at 6ft 3in, has the touch of a David Silva, clipping a delightful, flat pass to Jamie Vardy.
The striker turns inside and attempts a curler towards the far post, but cannot get enough bend on the ball.

Marko Arnautovic - with a heavily bandaged broken thumb - did well at the back and now evades the attention on Harry Maguire at the other end.
The Austrian manages to dig out a cross from the byeline, but Danny Simpson does well to head the ball away.

That's a brilliant cross by Aaron Cresswell and Cheikhou Kouyate should do better. These are the moments...
West Ham are creating opportunities but they can't score.
West Ham 0-1 Leicester
Ahh, come on, should be doing better.
A lovely curled cross into the box by full-back Aaron Cresswell is met by the head of Cheikhou Kouyate with a free header, but the West Ham midfielder cannot get enough contact on the ball and it rolls out of play.
Poor from the big man.

10 minutes to half time.
West Ham have improved after conceding that eighth minute goal, but are yet to find a way past Kasper Schmeichel.

I'm not sure why everyone is so certain West Ham will be relegated this season under David Moyes. I could easily see him getting sacked before he has the chance to take them down.

Now West Ham break after Riyad Mahrez gives the ball away.
Manuel Lanzini leads the attack and tries to shoot from the edge of the box, but in comes England international Harry Maguire with a well-timed challenge.
Howls of anguish from the home supporters.
West Ham 0-1 Leicester
Riyad Mahrez has recovered from that earlier incident and finds the ball at his feet again.
The Algerian dances left and right, the West Ham players are having to play to his tune.
He feeds the ball to Jamie Vardy down the left-hand side of the box, but no Foxes player can get on the end of his cutback into the six yard box.
West Ham 0-1 Leicester
The ball is in the air, there to be won and West ham's Cheikhou Kouyate gets onto it first.
Seconds later he is flattened by Leicester skipper Wes Morgan.
That must feel like you've been hit by a truck. A hefty knock.
West Ham 0-1 Leicester
Former PFA Player of the Year Riyad Mahrez picks the ball up on the halfway line and beats three West Ham defenders, but his right-footed shot from the edge of the area is straight at Joe Hart.
Mahrez stays down after the move having taken a knock to the ankle by Manuel Lanzini.

The West Ham supporters are urging their team on now, expecting something to fall their way.
West Ham 0-1 Leicester
West Ham are starting to push Leicester back and earn another free-kick in a promising position.
This one is down the left-edge and Manuel Lanzini elects to shoot from the angle, but Kasper Schmeichel punches the ball to safety.
West Ham 0-1 Leicester
First proper piece of work Kasper Schmeichel has had to do in this game.
West Ham get a free-kick which Manuel Lanzini swings dangerously into the box, Angelo Ogbonna flicks it on towards the back post but the Leicester goalkeeper sprawls low to his left to push the ball away.
It was sneaking in.

Leicester full-back Christian Fuchs does not score many and blazes a shot over the crossbar from long range.

It was worth asking the question from Marc Albrighton's situation. It's shoulder to shoulder but it wasn't a penalty.
West Ham 0-1 Leicester
Brilliant defending from Marko Arnautovic, you don't say that too often.
The Austrian has had a lot of stick for his performances for West Ham this season, but saves a goal for his team by tracking back and winning the ball off Jamie Vardy in the area.
The Leicester striker had been put through on goal and was about to pull the trigger before Arnautovic got back in the nick of time.

Shouts for a penalty as Arthur Masuaku tangles with goalscorer Marc Albrighton.
The West Ham man comes across and makes a clumsy challenge but referee Martin Atkinson waves play on.
Could have been given.
West Ham 0-1 Leicester
West Ham playmaker Manuel Lanzini has contributed zero assists so far in the league this season and you can see why.
The Argentine has time and space on the left flank, but his cross towards Andy Carroll is way too long and straight into the hands of Kasper Schmeichel.
