I'd like to see those changes first, because there's no doubt it will affect them. Real Madrid are the favorites for now, but they still have some gaps that Barcelona can exploit.
Several seasons ago I didn't like El Classico because of the different qualities where one team was stronger and the other team was weaker. This happened after the Messi-Ronaldo era. But this season El Classico is one of the matches that I am really looking forward to because both teams are in their best form and both also have equal quality. Real Madrid were slightly better and they only conceded 6 goals compared to Barca who conceded 10 goals. This shows that Madrid has a very good defense which of course is a homework for Xavi to dismantle Madrid's defense.
