La Liga is interesting. Even some of the weakest teams we struggled with (Las Palmas, Leganes) while slapping around some heavyweights.
It's far from just Barca for me and it's always been that way as a lot of the teams have historic character.
Refereeing is bad however and very biased in favour of a certain team from the capital. It's been that way ever since I can remember. And how far their influence reaches is fact hordes of people that don't even watch la liga have been gaslight into thinking it's other way around.
