The same thing is unlikely to happen again this season. Madrid have tried their best to strengthen their defense. At the same time , Madrid's overall performance is also quite strong. We have seen Real Madrid win all three matches this season. They have been able to perform well in every match. So, it is expected that this season's El Ccasico will be even more competitive.
This season has to be more competitive with Real Madrid's current performance, having won all three of their past matches. It is no news that there have being significant changes in Real Madrid's attack as they have registered six goals in their last three games and they maintain the first position in the LaLiga standings.
I believe with recent improvements and coordination, if Real Madrid remain consistent in their performance they would definitely win the league title this season, though with little resistance from Barcelona and Atletico Madrid being the major opposition in the league title but i definitely think that Real Madrid would be winning a title this season as last season recorded their worst season in a long while.
