Barcelona obviously. But most of all I think he hates "fans" like you. What annoys me is that in general there are two ways of supporting football teams:
1. You're a supporter of a team. This means you follow ONE team.
2. You're a supporter of a certain type of football. In your case, fucktard, this would mean you support teams such as Barcelona, Arsenal and Milan. Yet you support Juventus.
The thing is, you can't cheer for different types of football in different teams. That's contradictory. It basically means you're a gloryhunter.
What a narrow-minded point of view. You absolutely ignored the possibility of a combination of the two types which clearly exists.
You can be raised as a supporter of one team and will support it all your life through which would be the 1st option in your list. But that does not prevent you from adoring the way other teams play. And then you start cheering for them and from time to time your love for this club is growing even though their style of playing changes - you support two clubs now.
One will always be number one because you grew up supporting them, went to the stadium first watching one of their home matches and so on, and there is the second one which you love, too, and cheer for them as long as they don't play against your number one club.
Calling that gloryhunting would be extremly ignorant. Don't get me wrong, I also think supporting the top club in each league is definetly gloryhunting and a strange way of being a "fan", but that's not how it is in each case when two teams are supported.
