Barcelona needed a Jorge Saenz own goal to edge Leganes 1-0 and move seven points clear of Real Madrid at the top of La Liga on Saturday. Second-placed champions Madrid face Alaves on Sunday and have to play catch-up after Hansi Flick's side scraped their way to a narrow but vital win on the road. The Catalan giants are fighting for a potential quadruple this season and took another small step towards the league title at Butarque stadium.
