I will not doubt Real Madrid even without Ancelotti but they will easily find a suitable replacement, as has happened a long time ago, Real Madrid is one of the top teams in the world and they will do anything to be able to maintain and make this team continue to exist at that level.
However, it must be admitted that Ancelotti is one of the most successful coaches, not only Real Madrid, which he has given achievements to, but almost all the teams he has coached have been very successful.
And success will also continue to increase when the best coach is in a team whose mentality is very strong like Real Madrid. Even though last season Real Madrid did not win the La Liga and UCL titles, it is also not appropriate to judge that a team like Real Madrid has slumped. Because next season Real Madrid will definitely come back stronger and get more achievements like they have got in previous seasons. Especially now that Real Madrid has also got young players who might be able to help the team's strength to increase a little.
