I don't think Real Madrid, Barcelona, or Atletico Madrid will drop any points this week. All three teams will win their matches. While Atletico Madrid's match was a bit tough, I think they'll ultimately get the three points because they desperately need them. They played two very poor league matches. This is a chance to forget that.
Real Madrid will be playing from away and you know who their opponent is, Real Sociedad is not a team to underestimated because they literally use to prove stubborn most times when they meet Real Madrid as they don't concede many goals because in their last 4 La Liga games they conceded less than 2 goals in each of their home games and we shouldn't also forget how they gave Real Madrid a tough game in last season's Copa Del Ray semifinals where they ended 4:4 after extra time. Barcelona will be welcoming Valencia at the Camp Nou stadium, it shouldn't be a hard match for Barcelona so i believe they will win Valencia but for Atletico Madrid, they are yet to win a match after 3 games and their next opponent is Villarreal who is very much is form since they have won 2 matches and drew 1 game so they still have they willpower to maintain in their good start which means that Atletico Madrid may not get a win in that match, maybe they can get a draw.
