Robert Lewandowsk, Pedri and Sergi Roberto were on the score sheet as Barcelona moved to within two points of early pace setters Real Betis in La Liga.
Match Report
New arrival Lewandowski, one of five summer arrivals, notched two goals as Barcelona secured their first home win of the season.
The club's opening weekend fixture against Rayo Vallecano ended in a 0-0 draw with some questioning Lewandowski's form in that game but since then the Pole has put the doubts behind him, scoring four in his subsequent two appearances.
Pedri's first goal of the season, a tap in after good work from Ousmane Dembele, all but confirmed the outcome of the game on the stroke of half time.
Significantly, Jules Kounde made his first run out for the club after a summer saga that had appeared to have drawn on since the first swallow was spotted in Catalonia and west London.
