I can't rate Madrid now because they are suppose to be a dominating force in la Liga but for now they need to face a more stronger team and show this same performance and even more before I can say they did pretty well. As of last game against Osasuna I don't think Mbappe was playing like someone who have gotten used to the league and if not for the penalty which I believe many of the fans wasn't pleased about, I don't think they would have gotten a win and this game was like against a lower division team and the goals should have been more than 3 goals.
Madrid attack isn't as clinical as I expected, more work need to be done and if they feel they can beat the champions with this leg I'm seeing I think Barcelona will beat them again home and away even on a neutral ground.
The La Liga is Barcelona vs Real Madrid. There are no teams as strong as the two. Right now both have the same exact points and goal difference. The difference arise when these teams loses points to some random teams. There's no certainty which these team would be. Barcelona nearly lost some points against Levante. As the two teams has yet to play against each other and the same team, its still difficult to decide which of them are doing better.
Barcelona still is missing Lewandowski and the news is he has recovered and going to play next game. This could further boost the confidence of Barcelona.
