Ancelotti's achievements have brought the Real Madrid team to reach the semifinals of the Champions League, and this success can even make the Real Madrid coach proud.
It also seems that Ancelotti's failure to bring Real Madrid to the Spanish league is not a big problem because this is not the desired achievement point but the Champions League which is the main target for Real Madrid.
Actually all clubs want as many trophies as possible in one season. Likewise with Real Madrid. The LaLiga trophy is not something that is not important to them, but since they are so far behind Barcelona in points, it would be a waste if Real Madrid had to work hard for it. So Real Madrid prefers to save players for UCL matches.
Likewise the Copa del Rey trophy in the ongoing match. They will work harder to win the game. 1-0 for Real Madrid at this time has not provided a safe position for Real Madrid, because Osasuna is also playing very actively and carrying out dangerous attacks on Real Madrid's goal.
