Atletico had conceded only four goals in the Champions League this season prior to Tuesday's game but conceded the fifth to Leicester in the 61st minute when Vardy fired the rebound into the roof of the net after the ball broke to him in the box after Benjamin Chilwell's shot was blocked by a defender.
"I'm full of emotions, full of pride for the performance of my team". Instead, the quarterfinal second leg provided a snapshot of the kind of resolve that stirred a remarkable chapter in the history of Leicester City.

A closely-contested game saw Atleti control the opening stages, before Leicester came out fighting in the second half, ultimately enjoying more of the ball and nearly twice as many shots on goal as the visitors.
Whether Leicester returns to the competition in the near future appears unlikely.
"It is great to be in the semi-finals for the third time in four years". On the basis of that improbable and rapid climb, little will seem impossible for the years or generations to come at Leicester.
