Barcelona secured a comfortable 4-0 win over Real Sociedad on Sunday to move back top of La Liga. Aritz Elustondo's early red card gave Hansi Flick's side a comfortable afternoon with Gerard Martin, Marc Casado, Ronald Araujo and Robert Lewandowski on the scoresheet. Atletico Madrid beat Athletic Bilbao on Saturday to temporarily knock the Catalans from their perch, while Real Madrid, third, lost at Real Betis. Flick was able to rotate his side a little ahead of the Champions League last 16 visit to face Benfica on Wednesday and still move one point above Atletico.
