Real Madrid team is not in good form this season. Madrid's performance is not consistent. Real Madrid's performance in both La Liga and Champions League has been erratic. And Real Madrid have fallen far behind in the title race after losing against Barcelona.
On the other hand, Madrid's main rival Barcelona is able to perform well in every match. Barcelona won 11 out of 12 matches. Barcelona players are also very confident. Barcelona is now able to consistently perform well. So I'd say if Barcelona don't lose the truck then Madrid have no chance of winning the title. However, I personally consider Barcelona as the favorite for this year's La Liga title.
The difference in coach has brought a major difference for Barcelona. It has now fashioned an ability not only to perform but improve, continued as the team's confidence grows stronger, and positive results keep supporting their performance— evident by the difference in their position with Real Madrid at this time.
Meanwhile, Real Madrid seems to be struggling to keep up consistency in their game. They even often lose the points in games that they were supposed to win, and the defeat to Barcelona widened the gap in the title race. Looking at Madrid's current performance, maybe it's time for the management to make a rush-hour appointment of a new coach since the season is still long. By changing coaches now, this can give them the opportunity to get back on the right track without waiting for the end of the season and sinking deeper.
