It looks so far that Atletico will win the title, but will see how they will do for the rest of season. Barca has small chance this season as they need to rebuild team and so many players are just not performing. Also until fans don't come back to watch their clubs play, clubs will be in big trouble with finance.
My concern is only if they have injury free season. Injury have hit Barca and R. Madrid. If they stay away from covid and injury then fine. Once they have 3-4 people out due to covid or injury and they start losing 2 -3 points. That will affect them. Also Barca needs to win regardless. Win all the return lag against Both top teams to stand a chance
