In La Liga, Real changed everything very quickly, a few rounds ago Atletico was leading the table, and now Real is ahead of them by 4 points, the advantage over Barcelona is even greater. And as for Real, this is Ancelotti's tactics, they enter the beginning of the season with difficulty, but closer to the middle they get into good shape and this becomes noticeable, towards the end of the season they reach their peak form. I say this because they most likely will not allow anyone to displace them from the first place in La Liga.
This is where Ancelotti greatness lies, he is not in a hurry to step on the gas, he lets his players find a comfortable point first to create balance. When the time comes, they just stay and prove to be leading the top of the standings with a margin that can be said to be safe for a while. In fact, if you look back at the beginning of the season, Real Madrid was doubted, Barcelona led with full confidence but because they stepped on the gas too much while their young players were not yet fully consistent, their performance slowly declined and that's where Real Madrid overtook.
No coach wants his team to lose points, Madrid poor performance some time ago was due to many players operating in central positions being injured, this situation forced Ancelotti to work hard to find team balance.
In my opinion, Real Madrid was very lucky in the bad period experienced by Barcelona and Atletico, they managed to take advantage of the opportunity to dominate the standings. Ancelotti must keep his team's performance stable to maintain the points margin with their rivals because lately Barcelona has started to appear fierce, they also do not hesitate to slaughter their opponents with big scores.
