yeh that is so true, United have been the most successful English team in the past 10 years because they haven't changed their manager every time the team fails. Through his failures the team has risen past it and won countless trophies.
I guess the Gunners are in a similar but lesser level, they have always been successful but just not to the level of United.
It is defintiely a recipe for success, look how poorly Liverpool performed when there was so much uncertainty about the manager. Now they got Dalglish they need to secure him for the long-term.
