It's raining goals at the King Power and substitute Olivier Giroud adds a fifth for the Gunners when he sweeps the ball.

Jamie Vardy with another superb finish as he curls in. However, it's only likely to be a consolation for the home side.

That's a hat-trick for Alexis Sanchez and he gets it with the pick of his three goals.
Leicester's defence back off and Sanchez strikes a powerful low effort into the corner of the net.
That should be curtains for Leicester - even the Premier League's comeback kings can't rescue it from it here.

With this game in danger of petering out with 12 minutes left, Claudio Ranieri has one last throw of the dice and throws on Croatia striker Andrej Kramaric.
Danny Drinkwater is the man to make way.

Mikel Arteta gets his name on the book for a hand ball in the centre circle.
Leicester struggling to penetrate Arsenal's defence. Its going to take a bit of magic to get themselves back in the game.

If anything Arsenal look the most likely to score another goal here. On the counter attack Mesut Ozil finds a shooting chance on the corner of the box, but Ritchie De Laet makes a sliding block to deny him.

What was I saying earlier about Alexis Sanchez fancying his chances of a second goal here? Well he's got it.
Mesut Ozil lifts a high ball to the back post where Sanchez is on hand to beat Kasper Schmeichel to the ball and head in a second goal.
Leicester have come back twice from two-goal deficits in their past couple of Premier League games. Surely they can't make it a hat-trick can they?

A daisy cutter from Jeffrey Schlupp is easily gathered by Petr Cech as Leicester make a rare foray into Arsenal's half.

A clever Arsenal passing move opens up the Leicester defence and Alexis Sanchez finds himself with a shooting opportunity in the six-yard box. However, Leicester defender Robert Huth gets his sizable frame in the way to make a crucial block and Ritchie De Laet hooks the ball clear.

Claudio Ranieri has made a change at half-time and withdrawn Shinji Okazaki and brought on Andy King.

Steve Bower
BBC football commentator
"Jamie Vardy's hot streak continues but Theo Walcott and Alexis Sanchez, with his first Premier League goal of the season, have given Arsenal the edge at the break."
Leicester 1-2 Arsenal
Phew. Go and grab a half-time cuppa. That was a breathless first half at the King Power Stadium.
Leicester 1-2 Arsenal
Marc Albrighton teases a dangerous free-kick into the box but Wes Morgan is unable to get the decisive touch and the ball drifts out for a goal-kick.
Two added minutes at the end of this half.

Santi Cazorla's angled shot flashes just past the post. The Gunners are trying to take command of this game now.

Martin Keown
Former Arsenal defender on Final Score
"Alexis Sanchez is just a livewire, you're going to have to play him every week because he loves it. There was a bit of panic in the Leicester defence, it will be interesting to see now if Arsenal can slow the game."

Leicester's defence are caught on the back foot and Arsenal have cut them open like a knife through butter.
Hector Bellerin's cross from the right loops up off a Leicester defender and falls to Alexis Sanchez at the back post and he is left with the simple task of steering the ball into the vacant net.
That was Sanchez's first goal of the season. You sense it might not be his last in this game if it continues to stay so open.

Another counter attack, another goal at the King Power Stadium. Again, this graphic does not really show how quickly Arsenal broke forward to equalise, or the quality of Theo Walcott's finish, but the biggest difference between the Gunners' goal and Leicester's opener is that the visitors took four passes to get the ball up the field and in the net, not three.

After a frantic start the action has slowed up a bit as both teams catch their breath.
Arsenal's equaliser means no clean sheet for Leicester yet this season.
You may remember that Ranieri offered to buy his players pizza if they managed not to concede a goal. Perhaps Claudio needs to try a different culinary offering for that shut out?
