I would say that La Liga is very easy to predict because there are always two teams competing and one of them will eventually win the title. If you look at the last few seasons, you will see that either Real Madrid or Barcelona have won the La Liga title. The last season that ended, Real Madrid also did well in the seasons before this season, while Barcelona also performed well, but no other team could take the place of Real Madrid and Barcelona. In the coming seasons, we will see that either Real Madrid or Barcelona will win the La Liga title. Currently, Real Madrid's performance is not very good, on the contrary, Barcelona is performing quite well and they have added some new players to their club, so it is assumed that Barcelona will have a slightly higher chance of winning the league title next season.
Same as the English Premier League, in this case it's just one more team which still makes the league predictable also. Apart from Liverpool, Manchester City and Chelsea who else will win the EPL? The league title circles between these three clubs. After Chelsea won it last in 2027, EPL has been won between just Manchester City and Liverpool, so if you ask me, what's the much difference there between them and EPL I'm terms of winning the league?
