The 67-year-old announced his retirement at the end of the 2001/02 season but since making a dramatic U-turn on that decision he has led Manchester United to even more success. Having guided United back to the top of English football in 2007, after four seasons without a league crown, the Red Devils have gone on to win two more titles and the UEFA Champions League. The Scot's insatiable appetite for success is still as strong as ever despite spending more than 52 years in football and he insists he has no interest in ending his 23-year stay at Old Trafford. "My health will dictate how long I stay in the job," Ferguson told the Daily Mail. "That's the only important thing. It is what you have to value most and what you have to protect most because without it you cannot do justice to yourself, your family or whatever you do in life."
