Barcelona is much more effective than Real Madrid in their attacking paths. They have also scored a lot of goals and Lewandowski is the leader in the top scorers. Also, from what I have seen, the wingers are playing magnificently. Lamine Yamal has made a huge impact on the team. Especially for Barcelona, it is magnificent that such a player has come from the youth academy and they did not spend money on him. They are currently one of the serious candidates for the championship. I think they can be champions by the end of the year.
One of the reasons I think is making Madrid not appear effective with their attack could be conflict of interest, if they can get that sorted and not everyone wanting to gwt a goal at same time, they could have a more organised and target oriented attack. Barcelona has got this clearly figured out and handling it clearly in a manner that can put them at an advantage which has become very obvious before almost everyone at this time. Yamals impact is one that is undeniable and so far many others have keyed into this and has allowed him the leverage in the benefit of the team which ofcourse has helped the team in their performances and productivity this season as compared to last season.
