Yes, Real Madrid and Barcelona have always faced each other in spectacular fashion to win La Liga since ancient times.
I remember very well the challenges when Messi and Ronaldinho were there, pure spectacole.
no team can compete with them consistently
Girona, for example, tried last year but failed
Atletico Madrid, despite being competitive, struggles to excel, honestly i don't know why. This year they did well though!
yes, real madrid and barcelona have always challenged each other in a spectacular way to win the league since the past, after all they are the two strongest teams in the league, not by chance
In my opinion, much of their strength comes from a very large fan base that allows them to raise a lot of money and therefore be able to invest
