Is it true that you Spanish fans generally like to see the league do well in Europe?
Definitely not the same attitude for pl fans which would rather see the other teamssink and burn .
Premier fans may want the opposition to lose but they have more of a sense of ownership of the competition.
In my case it depends on sympathies with the teams and the degree of rivalry at the time.
For example I liked Barcelona winning against Sampdoria in '92 but I was very happy about the 4-0 defeat against Milan, as Deportivo had just lost the league against them.
I couldn't stand Cúper/Benítez's Valencia but today I would support them.
I'm generally happy if Villarreal get knocked out and I'm indifferent to Atlético. Watching teams like Liverpool get knocked out with shithousery gave me quite a bit of satisfaction. The same thing happened to me with Getafe against Ajax.
Barcelona situation is so bad that I'm happy for the teasing but not anxious to see them eliminated. The feeling when they lost against Mourinho's Inter was totally different
