As long as Barcelona are leading by less than three points and until they meet Real Madrid head-to-head, bookmakers will continue to rate them as clear underdogs against Real Madrid (which are still priced at ~1.50 even after dropping points). The fact that they have 9 points is not bad, but you can’t say that they are winning confidently - three minimal victories and in every game they are conceding goals.
Expect competitive run for the La Liga title this season, it's going to be amazing one because we have Barcelona, Real Madrid and Atletico Madrid, these clubs didn't sleep on because they made tough signings in the transfer window. Conceding a goal this time, it would be a top challenge for any Barcelona opponents because Barca is build with formidable qualities and tactics. Hansi Flick knows exactly what he's doing and not stopping. Barcelona will continue to lead on top of the La Liga table because they've the required positioning stands, with Hansi Flick empowering the squad with the fiercest game style, a more comfortable condition for La Blaugrana.
The season has just begun and we cannot conclude who will be topping the table because there are so many surprises that at e yet to come. Barcelona was able to win their two matches doesn't mean that they will continue like that till the end of the season.
There are some clubs that when Barcelona meets will make them drop points and other clubs will take over topping the table from them. Flickr is a good coach no doubt but I have not seen the best of him yet until in El Clasico.
