At some clubs, identity is everything.
Barcelona believe their team are more than a club, Liverpool are obsessed with their sentimental sense of honour and tradition and Athletic Club are dedicated to their Cantera policy of only playing Basque footballers.
Manchester United's sense of self—otherwise known as The United Way by some fans—is dogmatic, based as it is on some simple beliefs set down by Sir Matt Busby and later embellished by Sir Alex Ferguson.
These ideals can roughly be boiled down to playing entertaining, attacking football with a commitment to self-producing new talent and allowing brilliant footballers to express themselves fully.
Busby's vision for his teams came from a desire to delight his working-class spectators, as described by Mark Lomas of ESPN FC:
His philosophy was simple: Hard-working people toiled all week in anticipation of watching football and they deserved to be entertained. Those who frequented United games in the Busby era were rarely disappointed.
These open-ended principles, rather than forcing United down a strict and suffocating path of orthodoxy over the years, have helped to drive the club's desire to reinvent itself to win ever greater glories and overcome new and emerging threats.
From the overwhelming collective talent of the Busby Babes to the individualism of the Holy Trinity of Best, Law and Charlton, through to the power and pizzazz of Ferguson's side in the 90s and his more urbane, cautious counter-attackers of the 00s, every one of the club's great teams have shared the same DNA.
How will David Moyes uphold and advance this legacy and where can he fit into the tapestry of the club's traditions?
