"Who would have thought that at the start of the season?"
All over. Leicester City, yes Leicester City, are joint top of the Premier League at the start of November.
The KP rocking, Leicester have the ball deep in the Watford half. This one must be done...
Four minutes added on, four minutes between Leicester and a place joint top of the table.

"Vardy's form is incredible. If he is fit and raring to go he should start for England, because how often will he be on a goalscoring run like this? At the moment, Leicester are on course to be joint top of the league."
Into the final five of normal time, the Leicester fans still clapping so hard that they will be going home with blisters. The Foxes are going top (sort of).
Here are the heatmaps of Leicester forward Jamie Vardy and Riyad Mahrez (left), compared to Watford strikeforce Troy Deeney and Odion Ighalo. You can clearly see that the Foxes pair have made more inroads in the Watford box, and for now it is telling.
Leicester are still having the better of this, keeping the ball in the Watford half. At the moment, it looks like the Foxes will hang on.

This really is good to watch. Leicester were pegged back, but they are straight up the other end, Mahrez drawing a save from Gomes.

"Watford now have the momentum. That was as cool a penalty as you'll see from Troy Deeney.
"It was definitely a penalty, after some sloppy defending from Leicester. A clumsy challenge from Kante - if you're going to make a tackle like that you need to know who's around you and he just didn't."
Troy Deeney
Troy Deeney, cool as you like, sending Kasper Schmeichel the wrong way. Watford have hope.
Where has this come from? Kante on Paredes, definite penalty. Watford have a way back into this game...

"You won't find many noisier grounds than Leicester at this stage of the season."
Still so, so rowdy at the King Power Stadium. Watford haven't shown much in the way of getting back into this game. Leicester are joining Manchester City and Arsenal at the top.

The King Power is rocking, singing the name of Jamie Vardy. The Foxes are going (joint) top of the Premier League.

"What a way to take a penalty! Nerves of steel, Vardy smashes it right down the middle and into the roof of the net. He created it all himself, busting through.
"I understand why Gomes wasn't sent off, as Vardy was going wide of the goal when he was fouled. But a great spot-kick and now nine goals in a row."
John Motson
BBC Match of the Day commentator
"There was definite contact from Gomes. Wasn't it a typical Vardy run? It's not as if defenders don't know what he is going to do, but can they stop him?"
