After both playing in the Copa Del Rey and having European soccer to worry about midweek, it will be interesting to see how much rotation there is, but for Hansi Flick's Barcelona, there's quite an opportunity to take against Real Sociedad on Sunday.

Barcelona reclaimed top spot in La Liga with a comfortable victory over 10-man Real Sociedad. Atletico Madrid had leapfrogged them following their 1-0 win over Athletic Club on Saturday.

Barcelona cruised to a 4-0 rout over 10-man Real Sociedad to regain the lead in Spain on Sunday. Gerard Martín, Marc Casadó, Ronald Araujo and Robert Lewandowski scored a goal each to put Barcelona one point ahead of second-placed Atletico Madrid at the top of the Spanish league.
