Surely you don't want Real Madrid to.beat them, though? A club supported by a fascist dictator, that has had plenty.of financial support down the years when their finances were dodgy. That have supporters throughout Spain and beyond who really should support.their local side instead.
Da I'm not a fan of Real Madrid either, and I've heard they get subsidised by the state, which is ridiculous if true. Frankly, I'd like both sides to lose but whoever does win gets knocked out in the next round.
