The Reds' goalkeeper says the Blues may be slight favourites since they now have home advantage but he is confident Liverpool can still progress.
"The tie is still wide open and we trust ourselves to get through at their stadium," said Reina.
"I suppose now the advantage is with them because next time they will play as the home team.
"But this will also mean that at least they will have to play a bit more forward than they did on Sunday."
