DIFFERENCE BETWEEN FOOTBALL MANAGER AND COACH?

In the traditional sense, Manager are those who make tactics (long-term and short-term), organise the match day strategy,buys players,scout players and selects the team on match-day, makes the substitution, drop players etc... Basically, they're in charge of the team players and staff. A Coach is one who trains the team, i.e, fitness, skills, strength conditioning. Etc. They're pretty much like "TRAINERS". A coach may be involved in team selection but they will never have any "MANAGERIAL" responsibility outside the pitch.. Note that the difference between a Principal of a School and a Teacher in the school? That the same analogy applicable to a Manager and a Coach. The former should know about "ADMINISTRATION" and the latter should know how to teach and giude.
