Yes, I think the competition at the top of the standings this season will be determined until the end considering that all three teams have a realistic chance of doing so. Although they are a few points behind Real Madrid, Barcelona will also continue to improve and are ready to take over the top of the standings at any time. Atletico Madrid are currently leading and I respect them very much, but the La Liga title this season will of course belong to the two teams between Real Madrid and Barcelona.
After the 20th week of ATM and Barcelona went through it with less than satisfactory results, it means that now is the time for Real Madrid to reap huge profits if they are really able to get 3 points against Las Palmas today. Playing at home is indeed advantageous, but Las Palmas could give a surprise like Leganes and Getafe which made 2 big teams unable to bring 3 points. For Ancelotti please be careful, the more he can't win, the more his career at Real Madrid is threatened.
