As a player, Sir Alex Ferguson owned pubs in Glasgow, which he claimed was a hard business, and was determined to be a success as a manager so that he didn’t have to go back to being a landlord.

I got my coaching badges by the time I was 24. So when I became a manager at 32 years of age – which was young – I was ready. I had my badges, I had played the game, I think I could make a decision. Thereafter in an industry like that you have to learn or you don’t survive.

It’s a hard business. You’re fed up getting knocked in the head too many times on a Saturday night. So when I got the chance to be a manager I said – I’m going to win here, I’m going to be successful. The fear of failure comes into that. Where was I going to go after that? Back to the pub? No way.
