Barcelona missed a lot, maybe the reason is that they are going through a goalkeeper change, maybe there are some other reasons, and it is obvious that Real Madrid is doing better in defense now. In my opinion, both teams are doing well in attack, and both teams were able to score three away goals. And in La Liga, these teams will play each other only at the end of October, so we will be able to understand who is stronger only in their face-to-face confrontation.
It is true that Barcelona defense is not as good as their offense, but I do not agree with that on Real Madrid side. They have Carvajal back, Trent, Rudiger, Militao, Alaba, that new kid Huijlend or whoever, Mendy and Carreras, so considering their defense, Real Madrid is pretty solid. Maybe if you do not like these names then you may consider them not that great, but in most cases this is actually a good defense.
Barcelona has a better working offense, not the names, I mean if you compare name by name then Real has better offense too, but so far Barcelona offense works better than real's offense. So we will see how both will go, but so far both are doing wonderful jobs and scoring very well to get the wins they needed.
