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.
Real Madrid have many star players who won La Liga and Champions League title in previous seasons, and their quality is good, with great experience too. Bad performances in early of season are from player injuries and slow adaptation of Mbappe in his new club as well as a central attacking position. Now he is playing better and with less injured players, Real Madrid are nearly back to their best form, and their first position in La Liga is not surprising.
Each team will play 17 more matches. So I would say that Barcelona still has a chance to grab the top spot in the table. But for this, Barcelona must win consistently. At the same time, Madrid will also have to lose points in a few matches. Since Madrid's performance is quite stable, it will be very difficult for Barcelona to regain the top spot in the table.
However, the Barcelona team is still quite strong. Raphinha, Yamal and Lewa in the attack are in great form. So it may be possible for Barcelona to continue their good performance. But I am not sure whether Madrid will lose points. Real Madrid is ahead by a large margin of 7 points.
Many matches in La Liga and opportunities to win the league title is for all top clubs like Real Madrid, Atletico Madrid and Barcelona. At highest competition like this, positions of top clubs can change very quickly and Barcelona can keep fighting for a chance of returning to a first position. They are showing strong recently especially in attacking, but in these won matches with many goals, Barcelona still shown problems in defense. Defense can be biggest factor on whether Barcelona win La Liga title or not.
