Sir Alex Ferguson

Ferguson is an adopted Mancunian who embraced the city as his own. His 27 years as manager is a record that will never be broken. United started life in 1878, and remarkably Ferguson has managed more than a fifth of their matches since then, winning 13 league titles, five FA cups and 38 trophies. Nearly half of his most successful team was Mancunian – Ryan Giggs, Paul Scholes, Nicky Butt, the Neville brothers and, er, David May. One might argue Giggs and Scholes should be in this top 10 too. Giggs made his debut in about 1936, and Scholes is, as Xavi has said , “the best midfield player of the last 20 years”
