This year the liga teams are playing better, after barca almost not loosing any game last season looking at the scores this year you can clearly see that it has been more difficult for the good teams in the liga. This year madrid has had a difficult time playing against most of the teams of the liga and atletico has not had its best year also.
For the german teams dortmund has played great the first half of the season but they have to keep it up if they want to win because bayern has more than enough team to try and win it again.
Italian teams are not good on global level currently, crazy how they got eliminated in the champions league and juventus is the only one that has a chance to win the champions.
