Sir Alex Ferguson is one of the best managers in world football. He was in charge of Manchester United for a long time and helped the club to become one of the European powerhouses.

Ferguson was responsible for unearthing some of the best talents like Cristiano Ronaldo and Wayne Rooney. A new documentary is releasing on Sir Alex, named Sir Alex Ferguson: Never Give In.

Speaking to the United’s official website ahead of the release of his new documentary he outlined his approach to transfers.

Ferguson said: “Some players were absolutely natural footballers, natural talents. But there were other players who shared my determination.”

“They maybe weren’t the best players, but they made themselves the best players because they had something inside them too.”

The Scottish coach learned on the mental side of the game from his first taste of defeat in charge of a team. Ferguson said: “I wasn’t expecting it, I went into the game with my eyes wide open, thinking this was going to be easy,”

“We lost 5-2 to Albion Rovers, I was the manager of East Stirling. I made sure that my players had a mental toughness about them from that moment on.”

Ferguson brought names like Eric Cantona, Wayne Rooney and Cristiano Ronaldo to Manchester United, and he believes instinct played a part in spotting good players like them.

He explained: “I believe in instinct. I had a good instinct about players and a good instinct about watching players I maybe wanted to buy.”

“I knew that looking at certain players that I could see traits that told me they were Manchester United players, or Aberdeen players or St Mirren players.”
