The season is still very fresh, I think that is why the likes of Athletic Bilbao and Villarreal have occupy the top. I don't have too much confidence for them to stay at that level when the season reaches the middle. Currently real Madrid are with points which is actually a good start for them and I know there will not want to leave a chance because they have suffered a lot last season. I think it's only barcelon that is still finding it difficult to get to their good track despite the season is still at the bottom. Girona haven't picked their good form this time around but I hope they will get back after the international break.
This is still a long way from the finish line. I'm sure there will be many changes. There are many teams capable of causing surprises at the beginning, but they struggle at the end. There are teams that are capable of staying stable. A long league season with many competitions will affect team performance. Injuries, fatigue, and all other factors will have an effect. So I think all teams will continue to work hard to win every game, so they don't lose points because every point is the key to a team's success in reaching the finish line.
