Sir Alex Ferguson became a ferocious gum-chewer on the advice of former Manchester United physio Jim McGregor - to help soothe his nervous cough.
McGregor offered to prescribe medicine for Fergie's cough the night before his first game in charge of United at Oxford 25 years ago.
Ferguson refused, saying it was "just something I do," but McGregor revealed: "He started chewing gum during games on my advice.
"The coughing would start during the match, so after a time I plucked up the courage to suggest he should take some chewing gum. 'What do I want f****** chewing gum for?', he retorted.
"He also liked the odd spit, so I thought chewing gum would kill two birds with one stone. Eventually he accepted some chewing gum and that became a tradition during future matches

"He also ended our custom, started by his predecessor Big Ron (Atkinson), of allowing the coach driver Derek Sutton to sit with us in the dugout at away games.
"Sooty, as he was known, plonked himself on a dugout seat at Oxford's Manor Ground to be met by a Fergie stare followed by, 'Who the f*** are you?'
"Safe to say that was the last time Derek got anywhere near the dugout again."
