Liverpool midfielder Gini Wijnaldum insists his team can still qualify for Champions League semi-finals.
The Reds went down 3-1 to Real Madrid in the Spanish capital on Tuesday.
They will play the second leg at Anfield next week, and Wijnaldum says it isn't impossible Liverpool could overcome the deficit.
He told the club's website: "It's always good to have an away goal. Unfortunately, they scored one after we scored.
"So I have to say it would have been easier if it was 2-1 or we scored [to make it] 2-2. Now we have to score two and make sure we don't concede.
"It's not impossible, [like] we've shown in previous years, but it's difficult."
