Fermin Lopezs first-half brace and second-half goals by Dani Olmo and Robert Lewandowski earned Barcelona a 4-2 Champions League win at Slavia Prague on Wednesday.
The result keeps Barca in contention for a top-eight finish in the league phase, which guarantees direct passage to the last 16.
The Catalans face FC Copenhagen at home in their final league phase game next week.
