Yes right you are. Barcelona, Real Madrid and Athletic Bilbao is must potential team on LaLiga series to win Championship. These 3 teams always win LaLiga series. And among them, Real Madrid and Barcelona have the record of winning the most matches. Xavi is one of Barcelona's best guides Barcelona has become a very famous team thanks to Xavi. Watching the game between Real Madrid and Barcelona feels like watching a tiger fight
The list of potential teams to win the trophy this season should include Atletico Madrid, which you forgot. Just like Barcelona and Real Madrid, it's coming again with promising performance. I remind you that if atletico madrid was able to taking the third place last season with 1 point gap to the real madrid. Atletico madrid has almost the same record as real madrid last season. It's only less 1 point compared with madrid's final points which were 78 points while atletico was 77 points.
It surprises me that how girona will able to perform greatly during the early season as it was almost winning all of matches. The winner of la liga will always be real madrid/barcelona/atletico madrid.
Bilbao was not strong enough in winning la liga.
Over the years it's either Real Madrid or Barcelona that's dominanted the Laliga and the next club that's always follow suit either in third or fourth position is Atletico Madrid, they don't really put more effort like Barcelona or Real Madrid put to carry the league, they're always comfortable with the top 4 position so far they qualify for the Champions League competition,they're currently in the fourth position and have won 2 matches out 3 drawing 1 which makes them unbeaten so far, I would had love to see how they'll perform against Sevilla but I got postponed.
Sevilla is another big club in LaLiga, they are the club with the highest holding Europa League trophy and has been competitive in the league over the years but this season they've not been impressive since losing the Super cup to Manchester City, so far they're currently at the bottom of the table and has lost all three matches they played, Girona is surprisingly impressive and are above Barcelona in the league, but don't think they'll be able to maintain their form they'll begin to drop points sooner or later.
