Liverpool pulled off one of the great Champions League comebacks, defeating Barcelona 4-0 for a 4-3 aggregate victory in the last four.
Divock Origi scored the opener early on and Liverpool led at the interval.
Two strikes in two second-half minutes from Gini Wijnaldum stunned Barcelona and levelled the tie.
And a quick corner from Trent Alexander-Arnold caught the visitors napping, allowing Origi to score the all-important fourth.
The Reds return to the final for a second straight season, and will meet the winners of Ajax vs. Tottenham, who face off on Wednesday.
