Liverpool will have to defy the odds once again in Europe on Wednesday night if they want to secure their passage to the Champions League semi-finals.
Jurgen Klopp's side are on the brink of crashing out of Europe following a tame 3-1 defeat to Real Madrid in the first leg of the quarter-final tie in the Spanish capital last week.
Vinicius Junior and Marco Asensio were on the scoresheet for Los Blancos as they put one foot in the semi-finals. But Madrid will know that Liverpool have been here before, most recently when they stunned Barcelona at Anfield after a 3-0 deficit from the first leg at the Nou Camp two years ago.
