Last season, the competition in La Liga was also not so tight. Real Madrid was at the top of the table from the start and no one could overtake him. Clubs like Sevilla, Barcelona, and also Atletico Madrid at that time were also having poor performances, making it easier for Real Madrid to always be in top standing.
As we have seen this season, Real Madrid may not have a smooth road. Barcelona has big ambitions to have a place at the top and start. To be honest, Real Madrid still can't be beaten easily, at least Barcelona and Real Madrid have potential in 1st and 2nd positions.
Sevilla now has opponents to be able to compete with Atletico Madrid, so their target does not need to be high to beat Real Madrid or Barcelona. Then Atletico Madrid can still compete with the three clubs above.
