Lewandowski double restores Barcelona's lead over Real

Lewandowski has scored nine goals in his last nine league games and has 25 in the competition, three more than Madrid's Kylian Mbappé. 

Barcelona went in front with an own-goal by Girona defender Ladislav Krejci in the first half. Ferran Torres added the fourth goal for Barcelona in the final minutes at Montjuic stadium.

It was Barcelona's sixth win in a row in all competitions, and 11th in the last 12 matches. Hansi Flick's team are yet to lose in 20 games this year.

Arnaut Danjuma scored early in the second half for mid-table Girona.
