I'm not sure if I'm the only person that have notice or it's just recent that I came across this, any season that Real Madrid song win El clasico, they hardly win the Laliga trophy, two season before now they lost El clasico to Barcelona and in the end, Barcelona won the league. That means any season Barcelona is able to win the Laliga, they do also have the power to win them in any El clasico so it's very possible that it's too late that this season belongs to Barcelona already.
However, since Barcelona is not far yet with their points, I don't want to think my theory will comfirm this season, there are lot of things and room for many things to happen. Things like having red card and losing match, things like injuries and many more unforseen circumstances that can happen to teams, it can still happen to Barcelona, Real Madrid or even Bilbao. We just have to sit, watch and enjoy more shows that will b coming from April and May.
The La Liga competition is still very competitive, Barcelona is certainly not safe at this time because the difference is only 3 points. Moreover, the two teams are still facing each other, at the beginning of the season Real Madrid was also far behind Barcelona then they managed to overtake Barcelona at the top of the standings and now Barcelona has managed to overtake Real Madrid again at the top of the standings because Real Madrid has not been consistent in the last 5 matches.
That will also happen if Barcelona does not focus on La Liga, especially from my point of view Barcelona is currently consistent because the pulse in the front line is in Lamine Yamal, without Lamine Yamal it will be dull even though collectively Barçelona's game is good but without Lamine Yamal Barcelona will have difficulty because he is very vital for Barcelona.
So as has been said, this competition will change if unexpected things happen such as red cards, player injuries and if Lamine Yamal is injured it will affect Barcelona's position at the top of the standings. Moreover, Barcelona's schedule is also very tight, they will also face Atletico Madrid in the second leg of the Copa del Rey which we know Atletico Madrid's game is very tough and rough because both teams will play a life and death match in order to qualify for the final round.
