Leicester overturned a first-leg deficit to stun 10-man Sevilla and book their place in the quarter-finals of the Champions League.
The Foxes, in the competition for the first time in their history, trailed 2-1 from the away leg in Spain but goals from Wes Morgan and Marc Albrighton saw them progress 3-2 on aggregate.
Sevilla, who saw Samir Nasri sent off for a second booking in the 74th minute following a clash with Jamie Vardy, missed a great chance to get back into the game when Steven Nzonzi saw his penalty saved by Kasper Schmeichel 11 minutes from time.
Joining Leicester in the last eight are Juventus, who saw off Porto 3-0 on aggregate.
The Italian giants had done much of the hard work in Portugal when they earned a 2-0 lead, and they finished the job off in front of their own fans on Tuesday.
Paulo Dybala netted the only goal of the game, slotting home from the penalty spot in the 41st minute after Maxi Pereira had handled the ball in the area - earning the Porto defender a straight red card in the process.
