All in all, it was an electrifying night for Leicester.
Despite being thoroughly outplayed in the first leg, Leicester somehow managed to come away with only a 2-1 defeat. The fact everything can change in an instant creates an immediate tension and a rare heightened atmosphere.
With the build-up well underway ahead of tonight's second leg, here are THREE reasons why Leicester will win and indeed progress to the last eight of the Champions League... The question was, could he do it again at Leicester's first home knockout game? The heat had a bit to do with it as well in Sevilla, they are used to play in it week in week out. By contrast, Leicester were doing everything rather tidily, and strongly.

But six minutes later, Riyad Mahrez swung a free kick to the far post, where Morgan got a knee onto it and bundled the ball into the net. It wasn't the most aesthetically pleasing finish, given it rolled down his shin and in, but that didn't matter.
Sevilla dominated the final 30 minutes but its task was made harder when Nasri, who was booked in the first half for a petulant swipe at Wilfried Ndidi's ankles, collected another yellow card for going head to head with Vardy and aiming a butt.
Three games as Leicester boss - three wins. They suddenly couldn't live with the pace of Shakespeare's side.
Vardy had chances to put the game beyond doubt in the closing stages but despite missing two sitters by his own high standards, Leicester held on to ensure that their historic fairytale continues. They were hands evidently ready to grasp any opportunity, too.
Los Nervionenses were quickly out the blocks with a positive start in the second half, as the Foxes defence sank deeper and deeper with every passing minute. Sergio Escudero hit the bar with a vicious, dipping long-range effort, but two minutes later, Leicester had a second.
Leicester, in their next attack, went straight up the other end and doubled their lead.
It should really have ended 5-0 to the Spaniards in the first leg if not for their wastefulness and for Kasper Schmeichel between the sticks, but that away goal will give their opponents belief.
It was very soon Leicester who had an extra man, however.
The Foxes should have made it 3-0 shortly after the hour mark as Vardy scuffed his shot with the goal at his mercy, and the England global held his head in his hands as he spurned a golden opportunity in the box.
The drama increased moments later, with the visitors awarded a penalty after Vitolo went down under pressure from Schmeichel.
The production is one of William Shakespeare's most famous of all. He blazed over, and was literally smacking himself in anger. A banner depicting Craig Shakespeare with a Doberman dog was unfurled at the Kop, accompanied by the words "Let slip the dogs of war". We have massive games coming up and we have to focus on that.
