It seems quite obvious to me that Ancelotti will remain at the club - in the end, with the crisis Real (in the crisis of which he is not to blame at all), he reached the semi-finals of the Champions League and even lost La Liga, but overall it was a good year. If he had such results with the transfers that he requested and would have received, then it would be a different matter, but Mbappe remained at PSG and Real refused to fight for Haaland.
And I do not believe that Ancelotti himself can leave (without dismissal or not renewing the contract) from Real to the national team (of any country). Club football >> national team football if we are talking about top clubs.
Ancelotti will remain in real madrid till the end of this season. He will be going to the brazil starts from next year. Ancelotti has been committing to be stay in madrid for another one year. Haaland can't be bought from city as the release clause has not activated yet.
Haaland has a release clause that is worth €200 million. The contract comes into effect in 2024. However, the release clause is only valid for clubs outside of the (English) Premier League. According to The Athletic, the release clause of Haaland will decrease each year, upon activation in 2024.

This news still needs more confirmation from him, but it's actually making sense.
