The sacking of famous manager, Maurinho at famous club MenU remind of ongoing projects which fail and looks nowhere to complete on time.
Scenario and reason of failure almost same. Jose was best manager in the world with best club in the world. They have expertise and money to progress but stuck.
When staff or players start didn't give their hundreds persen commitment, then performance will drop. It made worst when technical or tactical also didn't resolve or wrong.
Change team head was normal solutions taken by owners buat staff or players still the same.
As MenU case now they performed with new boss but same players.
Same case when i rescue few projects with same staff which finally completed.
But what we always lack was timing gor change. Sometimes damage already bad and very costly.
