Ancelotti has given his best to Real Madrid since he became their headcoach, and until his declining period, And I guess most of these club has understood his tactical system of play, it now seems he's not doing his job as job as supposed.
Ancelotti game tactics are outdated, there are several reasons why Ancelotti should leave Madrid immediately: he has lost his magic, he is less competitive with modern coaches who implement systems, data analysis, fast transitions, high intensity and implement structured attack patterns. Meanwhile if we look at Ancelotti still relying on player instincts, uncontrolled ego, unclear ambition, attack styles that often collide with each other. Imo when they were slaughtered by Barcelona and Arsenal, it was a strong warning. Young players like Vini, Mbappe, Rodrygo and Bellingham need a game framework because it would be a shame if their good qualities were not utilized properly.
