It seems like you are too sentimental about what other members have expressed here. If you are a Madrid fan, of course it is natural that you want your favorite team to win, but there is nothing wrong with fans of rival teams also hoping that Madrid will lose, right?
If you say that when Barcelona won, no one complained, of course you are wrong because as far as I know, many members here also complained about Barcelona and I think maybe the people who complained were Madrid fans, because the rivalry between the two teams has also affected the fans of both teams.
I personally am not a fan of the Spanish league team but to be honest I quite enjoyed the match, winning by a narrow score (1-0) certainly indicates that the match was tough and full of tension throughout the match, if you saw the match of course you know what Modric experience was like able to bring change to the match with his single long-range goal.
Yes, I think that is common among both fans. The bad side of both teams will always be there for their respective fans because basically their rivalry affects many things. I am a Real Madrid fan without hating Barcelona as a competitor, however some Real Madrid fans hate Barcelona regardless of what they have achieved in different seasons.
I would call them hardcore fans who absolutely do not want any better team than the one they support. I tend to be neutral about a match and enjoy it instead of worrying about trivial matters. Barcelona and Real Madrid are two great teams in La Liga, both dominate La Liga with titles and that is why I love La Liga.
