Borussia Dortmund v Atletico Madrid (agg: 1-2, 20:00 BST)
Borussia Dortmund have a job on their hands if they are to reach the semi-finals after losing the first leg at the Wanda Metropolitano 2-1.
Dortmund boss Edin Terzic hopes a sold-out Westfalenstadion crowd of 81,500 can help his side mount a comeback.
"It's unique. It's regularly sold out and it has helped us countless times over the years," he said.
"We need a good result against Atletico and we're pretty sure our supporters want to make that happen and create a good atmosphere.
"So we want to pay them back."
