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.
It seems that is indeed Ancelotti's tactic, he wants to give his arch-rivals a chance to appear confident and start the season with high spirits, but Barcelona did not think about the impact that arises when the club is too excessive in every match, the effect is that the players quickly become tired and the club's performance decreases and that's where Real Madrid's game begins, namely when approaching the middle of the season Madrid began to refocus and did not let any club hinder them, even Barcelona itself, so Real Madrid can now lead the standings with a big advantage and their balance is maintained because Ancelotti has conditioned the players not playing too excessive.
