Divock Origi was the unlikely hero as Liverpool pulled off the greatest semi-final comeback in Champions League history with a 4-0 second-leg victory to complete a stunning 4-3 aggregate triumph.

The odds were stacked heavily against Liverpool after both Mohamed Salah and Roberto Firmino were ruled out with injury following a 3-0 first-leg defeat last week in Spain.

But Origi gave Liverpool hope with a seventh-minute goal at Anfield before Georginio Wijnaldum scored two quick second-half goals to level the tie, setting the stage for the Belgian to strike the decisive goal 11 minutes from time.

Liverpool will face Ajax or Tottenham in the final in Madrid on June 1.
