After what Madrid experienced in the UCL, the players condition must be in a slump. Plus there are rumors that Ancelotti will leave at the end of this season, precisely after the CDR final. Like it or not, Ancelotti has given his best but his era is indeed over and Madrid must be able to adjust to the modern era game with a coach who has a better system. The La Liga trophy will be easily locked by Barcelona so it is quite difficult for Madrid to catch up on the points even though the difference is 4 points but in fact the quality of Real Madrid game is still far from ideal.
I would agree with you that Ancelotti is the best coach in the la Liga, his departure from Real Madrid at the end of this season would leaves Real Madrid with a large vacuum that will be difficult to fill as they're very few coaches who could manage a club as big as Real Madrid like Ancelotti. This is a coach that has won the LaLiga, Super cup and the Champions league for Real Madrid. I think after his exit from the club, Real Madrid should build a monument to immortalize Ancelotti for his contribution to the club. It will be a great honour to a more deserving like person like Ancelotti, Although Real Madrid performance this season hasn't been a good one as most of their players are out forms and shape. Obvious The like of Kyllan Mbappe hasn't been seen much this season as the club have been struggling to win matches and outpace Barcelona for the title race. There Loss to Arsenal Home&Away in the Champions league is a clear evidence that all isn't well for Real Madrid. I expect to see an improvement in them from next seasons especially from some key players like Vicius Junior, Rodrigo and Kylian Mbappe .
