What happened to Barcelona in the game against Real sociedad was never expected, I'm not surprise of it because football is full of surprises and sometimes we can't predict what the outcome of a game would be. Sociedad is just lucky to win the game , this lose is what Barcelona would learn from. Barcelona still remains the best team in laliga for this season and this lose will be a motivation for them to get more points.
The thing is that you don't look down on little things and this is in the case of Barcelona because last season was terrible for them, and their is no way that we are going to be to compare the both of them now the way at which Barcelona is going they are the potential winners because who else do you have confidence in, that you think they will be able to win if not bacelona and I actually love the way they decided to pickup, and even if I love Madrid Barcelona gave them a good season at least next season they will be able to prepare better because their is no way that you won't notice that Madrid is struggling and the best team now in the premier league is not more than Barcelona.
Isn't it too much to say that Barcelona is the best this season and can be the winner in winning the title, all of this is still early and we can also see that in football competition it will run full season, don't be disappointed when you see Barcelona experiencing setback and failing to win the title because competition will still run very long in the future.
I admit that Barcelona this season at the beginning showed significant changes even much better than last season, but the question is whether it is possible for them to continue to perform optimally like this consistently this season ends.
