The best thing Real Madrid can do is to consider this season complete and prepare for the next season.
The season is going and they still have some tasks to complete. Protect their second position in La Liga that is related to prize money at the end of season. Winning Champions League as they already go to its quarter finals. Their coach and players can not think of holidays in summer too soon at least not in near future.
Maybe that's why the news about Carlo Ancelotti comes out. Maybe that's why the news about Haaland and Real Madrid are coming out. I do not know. There is a problem there. And they need to do something to solve it. Despite having financial problems at the beginning of the season, Barcelona made good transfers. Maybe they might consider spending some money on the competition too. On the other hand, Carlo Ancelotti's biggest trump card will be the Champions League. If he's successful there, no one will care what's going on in the league this season.
Very likely Ancelotti will have to leave Real Madrid. In the past, even Del Bosque had to leave Real Madrid after winning Champions League with them. They are a very ambitious club and their President Florentino Perez can make hard decision for future of the club. He does not mind about what you did in the past, if he feels disappointed and think a club needs a new coach to have better results, he will fire you.
Rumor is Mourinho is one of Real Madrid prioritizes for their coach position after Ancelotti era.
