Sometimes people argue based on what they saw in some teams performance in some matches, because this season three teams are seriously fighting to be on top of the table and if you look at the gap of their points, i think Barcelona, Real Madrid and Atletico Madrid are in good condition to win this la Liga league competition title. In my own observation concerning those three teams who to win this title, I think Barcelona is the team that have that energy to win la Liga league title because they have defeated Real Madrid many times in this season. Real Madrid will manage to take second position in this season, because they are stronger than Atletico Madrid which they have proven it in the champions League competition, because they defeated Atletico Madrid 2-1 in the first leg to have the opportunity to achieve victory in the second leg.
As long as the points gap of the three teams is still close enough and they have also beaten each other in previous matches in different competitions, it is not a guarantee to become champions for one of the three teams you mentioned. Because a team like Barcelona can also slip up when they are hunting for points to stay on top until the end of the season because all three are still in the Champions League and also the Copa Del Rey which will make their players a little more tired than usual even though each coach will still play a role in rotating players to be more effective in maintaining the strengths in their respective teams.
The gap between them is still very close, so that's what makes us not have to rush to say who will be the champion. Also their situation is sometimes unpredictable, like at this time we see where in a short time finally Real Madrid had to drop from the top of the standings and even before that Barcelona also experienced the same thing. 12 matches left in La Liga this season, so anything is still possible. Moreover, the 3 teams in the competition certainly don't want to just lose and they will continue to fight to win the match in order to maintain their chances of becoming champions.
