If Madrid/Spain will attack Barca and Catalonia at every chance they get, then don't give them any chance. Be extremely careful, transparent and clear in everything you do. Rosell and Bartomeu did the opposite, they basically did the equivallent of painting a huge bullseye on the Camp Nou walls with this shit.
I agree that if some day Barcelona gets attacked and penalized for doing nothing wrong, then it's high time to leave Spain for good, as no one can survive in such a climate. But are we at that point now? Are shady deals like this really normal among european clubs, we're just being targeted? There are certainly many unfair things in the relationship between Barca and Madrid, but this mess is clearly Rosell and Bartomeus doing and could easily have been avoided.
