Spain's La Liga is mainly dominated by a few clubs, notably Real Madrid, Barcelona and Atletico Madrid. Other teams don't have good strikers and enough players due to the enough budget.
It's very painful to be a player for those other teams in the league. i know the players from other teams earn well and there is a chance that some other big team will sign them, but when i think they are just playing to stay in the league and not get relegated or they are fighting just to go to the champions league or europe league i really think it must be hard to play in teams other than real madrid, barcelona and atletico madrid
Indeed, it seems that is what other clubs are doing to survive and not be relegated in a short period of time. The La Liga season is still long, so every club other than the three above will always be fighting for the maximum place. Such as Sevilla, Villareal, and Real Betis as well as clubs trying to enter the top 10 standings at the end of the season.
