I agree with you that Barcelona will not be able to defend the title this season because Madrid is back with full force to run over Barcelona who dominated the league last season due to the poor condition of Real Madrid squad. The only strong club that played with Barcelona won them last season in the Champions League semifinals. I can't wait to watch the first El Clasico match and let me see what will be the outcome of the game.
Indeed the current conditions are different where Real Madrid has currently made many improvements, their strength seems to be back in good condition, it can even be said to be much better in the hands of Xabi Alonso but Barcelona also cannot be underestimated even though they have not made many player purchases, their strength in defending the title can still be relied upon, I think the title race will be much more interesting and tight between the two teams.
