Pablo Sarabia and Joaquin Correa scored in each half to leave the Spanish club a draw away from reaching the quarterfinals of the European competition for the first time in almost 60 years.
Vardy, who scored 24 league goals during Leicester's title-winning campaign, had the release cause in his contract triggered by Arsenal but he opted to sign a four-year extension with the Foxes in June. Albrighton continued: "We've come here and we've switched off from the league for a week or so - we've not got a game till Monday now so it's given us a good mental break from the Premier League". Schmeichel came up big for the guests, as the Dane saved a penalty in the 15th minute by making a good save on the attempt by Joaquin Correa.
Sevilla cruised to a 2-0 lead by the 62nd minute, and it should've been much more if not for the work of Kasper Schmeichel, but Jamie Vardy scored a precious away goal to keep the tie more than alive.
Christian Fuchs, who nearly was at fault for an own goal in the opening stages, was caught sleeping and Pablo Sarabia was on hand to head past Schmeichel.
It looked as though it could all be about to get derailed as they conceded their first goals in the competition, but they showed great determination to give themselves a great chance of advancing to the quarter-finals.
But Leicester won't go home too heavy-hearted after a spirited second half which it hopes will kick start its poor domestic season.
Sevilla dominated possession to such an extent that Samir Nasri and Steven N'Zonzi completed more passes than the entire Leicester team.

The charges were the first that included crimes committed while serving in his role as a team physician at Michigan State. Schuette and Michigan State University Police Chief James Dunlap are holding a news conference at 2:30 p.m.in Lansing.
"And Schmeichel believes Vardy's 73rd-minute strike could prove key when the teams meet in the second leg in Leicester on March 14".
"Common sense would say that someone who achieved so much from a team with so little can turn the situation around, but time waits for no one, not even someone as good as Ranieri who won the Premier League".
"We lost the game, that is disappointing".
By contrast, Sevilla were left to rue a slew of missed chances.
Leicester City midfielder Riyad Mahrez said his side's "English football" had helped get them back into Wednesday night's Champions League game at Sevilla.
Sevilla boss Jorge Sampaoli insists Leicester need to forget their title miracle to survive this year.
"We've had nights in the Champions League where it's gone well where that could have been the turning point and it hasn't been. If it wasn't for him, it would have been a very different story".
