AS Roma coach Vincenzo Montella is convinced they can win at Shakhtar Donetsk.
The Giallorossi need a win in the Ukraine on Tuesday after surprisingly losing the home leg 3-2 under previous boss Claudio Ranieri.
"They are a quality team who haven't lost for 60 games, but they are beatable," said Montella.
"I'm optimistic because Roma are clearly growing. We have a better squad than our opponents, but we are aware that we have a feat to achieve.
"It's important that my players have the right stimulus. They have a certain style of play, but we have our characteristics too."
