Barcelona are 8th position on the table, but you should know it's only 5 points behind 1st placed Atletico and 3 points behind 2nd place Athletic Bilbao, all these could be easily covered in 2 and 1 game(s) respectively, so for now, nothing has actually been guaranteed.
Does Atletico Madrid have the team to compete for the title, can they be consistent? When last did Atletico compete head to head with the top two clubs Barcelona and Real Madrid for the title? The La Liga season is still very fresh and also Barcelona haven't found their form yet, they did invest far too much into the team this season to lose.
Real Madrid weren't that convincing last season and their team haven't improved that much to match that of Barcelona irrespective of them buying hazard (although he's good, he doesn't have much goals in him. Mostly a play maker). The season will end in this manner Barcelona, Atletico then Real Madrid that's my prediction.
