Real Madrid and Barcelona both lost two points. And Atletico succeeded in taking advantage of the situation by defeating Elche 1-0.
Yep, as expected that Atletico Madrid will continue to dominate La Liga with their current solid squad. While Real Madrid and Barcelona look unconvincing with the current squads, and it is proven that they just got a draw on matchday 2, even Real Madrid got a draw against a small team like Levante. If the situation has no change during this season, it is clear that Atletico Madrid will win again the La Liga trophy.
Now, Atletico Madrid is successfully leading the table. They can maintain the positions if they keep playing solidly. And gradually make a bigger point gap if Real Madrid and Barcelona got a draw again or lose points on the next matches.
With the current squad, it seems that Atletico Madrid is more stable in welcoming this season and will be a strong candidate as La Liga champions. Losing Messi is a tough thing for Barcelona but they have to accept it and I think they have to make improvements with the squad they have now.
For Real Madrid, If they want to stay in the title race then they will have to buy new players before the transfer window closes. Otherwise, Real Madrid will have a hard time at least until mid-season (the winter transfer window opened) because the current Real Madrid squad is not much different from last season's squad that failed to win a trophy.
