"I believe the target of anything in life should be to do it so well that it becomes an art"—Arsene Wenger.
No success attained by those in this list has been achieved without a dedication to craft similar to that of the Arsenal boss.
And although every manager included here will have wildly contrasting approaches to the game, they all share one, very common trait—the desire to win.
In compiling a list of the 50 greatest of the profession, and then attempting to put them into a definitive order, a simple equation has been used to complete this mammoth task.
The world's best will each receive a score out of ten in four different categories—Success, Consistency, Longevity and Current Reputation, with the total score then deciding each manager's placement. The latter category will prove the deciding factor in case of a tiebreak.
But if that doesn't make much sense now, have no fear, it will soon.
Of course, rating a manager's success is relative. Take David Moyes for example. Whilst at Everton, silverware has proved hard to come by, but in terms of exceeding expectations on a minimal budget, the Scotsman has been very successful indeed at Goodison Park.
But winning the Premier League or the World Cup will also weigh more heavily than say, an Eredivisie title.
Currently unemployed bosses such as Pep Guardiola and Rafa Benitez will be considered; however, the officially retired, such as Gerard Houllier and Luis Cubilla, will not.
Naturally, there is no right or wrong way to assess every contender's career achievements, and a list like this is designed to spark debate, rather than end it.
But enough of my preamble, here are Bleacher Report's 50 Best Managers in World Football.
