Wes Morgan and Marc Albrighton were struggling to comprehend Leicester progressing into the Champions League quarter-finals after their goals helped the Foxes continue their incredible European adventure.
Trailing 2-1 from the first leg of the last 16 encounter, the defending Premier League champions tipped the momentum in their favour when captain Morgan somewhat fortuitously turned in Riyad Mahrez’s 27th-minute cross.
There was nothing fortunate about Albrighton’s 55th-minute goal, though, with the midfielder firing low past Sergio Rico, and Samir Nasri’s dismissal with a quarter of an hour remaining seemed to end Sevilla’s challenge.
But there was still time for late drama as Kasper Schmeichel was adjudged to have fouled Machin Vitolo in the area - but the Leicester custodian atoned for his error by guessing right and saving Steven Nzonzi’s penalty.
That sealed a 2-0 win on the night and a famous 3-2 victory on aggregate over the reigning Europa League champions at a rocking King Power Stadium.
Morgan said on BT Sport 2: “Incredible, I can’t quite believe it. We’re newcomers in the Champions League, we didn’t expect to get this far and here we are.
“I’m not sure this is ever going to happen again, but we did it. We did it and we proved a lot of people wrong. It was a big game for us and a big night for everyone involved with Leicester and we’ve pulled off the impossible again.”
