Here is the moment that the Leicester skipper put them ahead for the first time in this tie.

Juventus are starting to look a little more dangerous in the Porto third. Mario Mandzukic heads straight at Iker Casillas, moments before Gonzalo Higuain's dangerous cross from the right is hooked away by the Porto defence with Paulo Dybala ready to pounce.

The Italian champions are still in second gear.

Schmeichel is forced to tip over a cross from the right from Gabriel Mercado. Sevilla take the corner short but when the ball is delivered it is headed away. 10 blue-shirted outfield players behind the ball.

If it was noisy before, it was ear-splitting as Leicester City captain Wes Morgan bundled that one home. Leicester City are how in control of their destiny - but concentration vital against a high-quality side.

It's a good job Morgan has the biggest thighs on the planet - he didn't know an awful lot about that goal! 

If we are honest, yes, Jamie Vardy won the free kick, but if we are honest, if that were a foreign player, we would be going berserk at that. 

Sevilla have conceded away from home in the Champions League now. They respond well to falling behind, though, and Ben Yedder goes close to a leveller with a shot that flies past Schmeichel's near post.

Sevilla have weathered the initial storm and are seeing more of the ball now. City win a free-kick on the edge of the box, though, as Vardy is tripped after nicking the ball. This is a great opportunity...

The Juventus players are strolling around like commuters killing time before the next train home. They're happy for Porto to play in front of them, barely breaking into sweat. No incision from the visitors yet.

Boos ring around the stadium as Danny Simpson is brought to ground by a hanging leg from Steven N'Zonzi. City appeared to have a pretty solid case for a free-kick there.

Sevilla spring to life on the counter with Wissam Ben Yedder holding the ball up before Pablo Sarabia pulls a shot from 20 yards wide of goal.

Magnificent atmosphere inside The King Power Stadium with incessant  noise and this Champions League tie is being played with a fierce intensity.

Leicester City are pressing Sevilla every chance they get, roared on by their supporters, but the La Liga side, the current Europa League holders, are standing firm and threatening with attacks of their own.

Oh, poor keeping from Sergio Rico. He comes out to try and claim Danny Simpson's cross, which floats away from him and leaves him stranded. Nervy keeping. Something to exploit?

First booking of the night goes to Samir Nasri and deservedly so. He boots Ndidi up in the air and down to the turf.

Beat the first man! Porto win a free-kick in a promising position on the left side of the Juve penalty area, up go the big lads from the back. But the delivery is weak and headed out by a Juve defender. 

That has raised the hopes of the Portuguese leaders though. They have dominated possession and territory in the past five minutes though.

Sevilla are a little rattled at the moment. They are finding it hard to regain composure and forcing the goalkeeper to kick it long - they are not used to that at all. 

Leicester are doing everything right so far. 

Adil Rami surprisingly takes the free-kick but slaps his shot high over the goal. Why did the defender take it?! Bizarre.

Down goes Vitolo in the Leicester half under a challenge from Ndidi and Sevilla have a potentially dangerous free-kick...

Leicester are bossing possession so far. Sevilla happy to dig in. They have the advantage and will want to head off this early home momentum.

Remember, the Spanish side haven't conceded away from home in the Champions League this season.
