We know how competitive La Liga is and only the strong survived. Real Madrid and Barcelona remained the only rivals for La Liga titles every single season over the past decades, often Atletico Madrid enter the race but they don't possess the kind of energy required to lift the title, not consistent and settled for lesser results. More reason I favour and fancy Real Madrid and Barcelona, always in for excellent results. Real Madrid sits top of the table, Barcelona ranked second and Girona demoted to third position after been humiliate by Los Blancos in their last game.
Over the years there are only two teams that's been dominating the league and that's Realmadrid and Barcelona and for any other team to start dominating they need to be as strong as both teams or even better than them,but i think it would take a while before we'll see another team dominate the League cause both teams are getting stronger every season and are currently the best in the world, however there are several teams that' tried in thé past to challenge their dominance but failed teams like Atletico Madrid and Sevilla.
However this season Girona have tried to get this far in the table but i doubt if they'll remain consistent cause they don't have a very strong substitution players that would help them on the long run when their 1st team players start suffering from injury or fatigue there to maintain their form they needs to include more players to their team during the winter windows.
