Kasper Schmeichel revealed his relief after Leicester reached the Champions League quarter-finals.
The Foxes kept their European dream alive on Tuesday after Wes Morgan and Marc Albrighton scored to complete a 2-0 win over Sevilla and send them through 3-2 on aggregate following last month’s 2-1 defeat in Spain.
Samir Nasri was sent off after clashing with Jamie Vardy minutes before Steven N’Zonzi’s penalty was saved by Schmeichel and boss Jorge Sampaoli was sent to the stands.
The Foxes could face holders Real Madrid, Barcelona or Juventus next month but Schmeichel was more concerned about edging past Sevilla.
He told the club’s official site: “There was so much relief when the final whistle went. It was an amazing evening, I’m proud of all the boys. The fans were absolutely magnificent and it was a great atmosphere.”
Schmeichel conceded a second-half penalty, bringing down Vitolo, but saved N’Zonzi’s weak effort - his second spot kick stop of the tie after denying Joaquin Correa in Spain.
“I can’t see how it’s a penalty but it was given and you have to move on and try to save it,” he said. “It (the clean sheet) is a testament to the boys, we played really well in the first half and it was always going to be tough to keep that intensity.
“We should have shut he game out but it was a great performance all round.”
Morgan opened the scoring after 27 minutes, with Albrighton adding the second 10 minutes into the second half and Vardy missing several chances to finish the game late on.
And captain Morgan admitted the Foxes had achieved the impossible ahead of Friday’s last eight draw.
He said: “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.”
