Barcelona coach Ernesto Valverde says meeting Slavia Prague is an important game for his team's efforts to secure qualification to the next Champions League round.
Barca meet Slavia Prague on Wednesday night.
"We expect a great rival, as they have shown in these two Champions League games that they have already played, and remember they eliminated Sevilla last year," said Valverde.
"They attack with many players, show their face, run a lot and will force us to have a great match.
"It's a fundamental game for us and for them.
"Things are starting to become clear and that's why the three points are so important."
