Yes I agree with you Barcelona will still lead the League and Real Madrid will be the second runner and probably and Atletico Madrid will be the third though that is my prediction on the forthcoming La Liga season.
But next season will be a tough tournament for Barcelona because all teams are getting reform to face tough team.
Hansi Flick is very well concious of the capabilities of the players in his squad. So flick was not interested in making any changes in the squad. This squad of barcelona performed brilliantly last season. And if the players do not face injuries , it is expected that barcelona will be able to perform well this season as well. On the other hand , real madrid has changed their manager. So there will be changes in Madrid's formation and match tactis. For this reason it is not surprising if Madrid's performance is a bit irregular at the beginning of the season. Madrid will definitely try their best to secure the La liga title. So the fight between Madrid and Barcelona will be more intense this season.
