Off goes Mahrez, very, very slowly, which earns him a yellow card for time wasting. On comes Daniel Amartey.

Nerves of steel needed now but the home side.

Oh. Jamie Vardy. How many chances do you need to end this?! Riyad Mahrez charges away on the break and finds the striker to give him a clear sight of goal, but instead he finds the stand.

To be fair, there was a bobble. Still should have hit the target, though.

Huge chance for Leicester!

Marc Albrighton plays a great volleyed cross without looking and it lands on the head of Jamie Vardy, who is eight yards out and steers the ball towards goal only for Sergio Rico to claw the ball out.

Remember, Sevilla still only need one goal to send this to extra-time. 

Another dismissal. Sevilla boss Jorge Sampaoli has been sent to the stands. He has been storming around on the touchline all half, but he has clearly said something out of turn. It has not been a pretty night for the Spanish side.

Not quite as much drama and tension over in Turin as there is in Leicester. Juventus are 10 minutes away from having their place in the last eight confirmed. Porto just want to hear the whistle and get back on the plane.

You'll probably remember that Schmeichel saved a penalty in the first leg as well. That'll do pig, that'll do.

He has done his homework.

It's a poor penalty - he doesn't have to fling himself. Not a tricky one for Schmeichel.  

Would you believe it! Schmeichel dives to his left and pushes away Steven N'Zonzi's spot-kick. Everyone on their feet, including Kasper's dad, Peter.

What a game this is!

Another twist! Vitolo breaks through and goes down under a challenge from Schmeichel and the ref awards a penalty!

It's pathetic from both of them to be honest. Really really poor. Vardy goes down like he's been hit by David Haye. 

A yellow card for both would have been fair. Vardy's reaction is pathetic. He's been no better than Costa was last night. 

You don't need to do that, Vardy. You are good enough without that behaviour.   

He has to be careful now - he is so full of adrenaline - one more silly dive, he is going to get himself sent off.

Vardy was also booked for his part in that incident. It is the cards given to Nasri that are far, far more costly to his side, though.

Big moment. Nasri is off! He has gone head to head with Vardy after a shove from the City striker. Vardy takes a tumble, as footballers tend to do in these circumstances and Nasri has his second yellow, followed by red.

The former Arsenal and Man City man takes his time to depart, returning a few times to have his say. But the upshot is this - Leicester have a one-goal advantage in the tie and now a man extra for the remaining 15 minutes.

Leicester are getting deeper, inviting pressure. Sevilla are pressing. They create an opening for Correa but Schmeichel is equal to his angled shot. Tense, nervous times.

Gonzalo Higuain might be the world's third most expensive player EVER, but his scoring record in the Champions League knockout stage is not worthy of that hefty price tag. 

The Juventus striker has only scored two goals in 21 knockout games, but goes close to adding another here. He spins and fires low past the far post.

This game is like a Juve training session now.

20 minutes to go, Sevilla really have to go for it. They have to just throw everything at Leicester.  

They haven't actually tested Kasper Schmeichel at all this half. 

Leicester must stay disciplined. Slimani fouls Vitolo and Sevilla have a free-kick in the City half. The delivery prompts some head tennis on the edge of the box before Escudero is tackled.

They need to find some composure to be honest. Some of the defending from Leicester is a little bit frantic at times. 

Keep calm - you are in control.

Big chance!

Sergio Rico dives to prevent Riyad Mahrez's cross reaching Islam Slimani in the box before Vardy follows up and smashes his effort wide. That could have ended it. As it is, City fans must resume chewing their fingers to the bone.
