La Liga is a farmer league, the top 1,2, and 3 always Barcelona, Real Madrid and Atletico Madrid, they just swipe their position and there's no club can compete against them. I think the reason why Real Madrid is successful in international competition is their key players are still playing, it's not like Barcelona where most of their players were retired and they need to make a regeneration.
Farmers league indeed lol
Funny as it may sound quite true also , these never change positions that much and its easy to pick the next team to win the cup in the next season based on this farmers league belief

Hope this changes in the coming years to make league more competitive!
We must be waiting until some billionaires from saudi arabia will acquire some mediocre clubs in la liga. The same thing like what happened in the EPL. After some saudi billionaires were acquiring some mediocre clubs and the tension in the league has been changing a lot.
There have been so many clubs that were climbing up even higher like manchester city.
Waiting for almeria, cadiz or even valencia to get saudi billionaires as the new investors.

This will so funny if there will be some mediocre clubs that evolved after it gets billions of money from its owner.
Im not sure if madrid, barcelona and atletico will able to always dominating the league.
