Yeah, however, there are still many matches left, surely there is a chance for Real Madrid to win the La Liga trophy. I won't give up to support Real Madrid, I believe Zidane will make some changes to cut the point gap between Atletico and Real on the table. We know that Atletico often makes unnecessary mistakes towards the end of the season. So, just wait for the time when Atletico drop their focus or maybe some key players get injured. Who kows what to happen in the future? 
Yes Real Madrid can come back and take a trophy like they did in the last season. The prob for it is smaller than the last season by some reasons. Their squad is getting older a little. Their defense system does still rely too much on Ramos. They did not find a good alternative for Luka Modric. Eden Hazard with his second season in Berbaneu is still struggling to adapt and his transfer can be a failure for Real Madrid. He is getting older too. Another important reason is this season won't have a sudden break like last one. The governments in the Europe and in Spain can manage better to fight with the pandemic, virus spread and the vaccination is coming. Atletico Madrid has a biggest prob to win La Liga. Barcelona and Real Madrid will fail.
