Manchester City must produce a comeback for the ages against Liverpool on Tuesday if they are to reach the Champions League semi-finals.
Pep Guardiola's side are trailing by three goals after suffering a 3-0 defeat in the first leg at Anfield last week, leaving themselves with a mountain to climb against the Reds.
They will have to score at least four goals without conceding - something they have already managed against Jurgen Klopp's side this season - to beat the odds and progress.
The victors of the tie will take their place among the final four in the semi-final draw this Friday.
