I hope to see Ancelotti stay in Rel Madrid especially when we know Real Madrid can hire better players for the next season and Ancelotti can have more tools for his work there, but for any reason if Ancelotti leaves Real Madrid this can't be easy find a coach for Real Madrid to replace him.
Ancelotti is not leaving Real Madrid. That has already been concluded. He will continue to be Real Madrid's coach for at least one more season. There was not official offer from Brazil even. Madrid trust him for the work he's been doing and they believe if its best he keeps leading the campaign.
Ancelotti is unlikely to leave Real Madrid. Ancelotti was first successful with Real Madrid. And secondly, Ancelotti is very loyal to the Real Madrid club. He will not be interested in leaving the club. Moreover, Real Madrid needs Ancelotti very much next season. Because their key player Benzema has left the team. There will be several changes in the team next season. And so Real Madrid needs an experienced coach like Ancelotti to stabilize the team. If Ancelotti is Real Madrid's coach, Madrid's performance will be consistent next season. Ancelotti's match strategy is excellent.
