Of course it is too early to determine who will take the title from Real madrid. Everything are making good performance at the start of the league it doesn't mean it will gong well like that. Most time some teams starts very well in the beginning but has the league continues things change. Their are some teams that will start badly and may improve middle of the league. Real Madrid are too strong to lose the title.
I agree that it is too early to judge Real Madrid as the winner of La Liga this season. It is still the first match of La Liga, we still cannot determine which team to dominate La Liga. However, if we consider the current performance of the teams in La Liga, Real Madrid becomes the favorite to win it. Real Madrid also has a good squad that played quite solid during pre-season matches.
What is clear is that this season will not be as easy as last season. If last season Real Madrid dominated Laliga without any fierce and challenging resistance from other teams, it is different from this season. In fact both Barcelona and Atletico Madrid have come back and proved that they too are struggling this season. So, this season will be very interesting. There are still many surprises to look forward to as to who the winner will be. Indeed, Real Madrid are the favorites to win when viewed from several lines. But Barcelona may also be able to because of the composition of the current squad, just polishing the solidity of the team and strategy of Xavi.
