Manchester United great Sir Alex Ferguson admits he never took notes during games.

Two of his successors at United in Jose Mourinho and David Moyes have been known to do it, as well as Leicester boss Brendan Rodgers.

"As a manager I depended on my memory," Ferguson said. "You see games today where some managers take notes during the match. I never did that.

"I always depended on my memory and when I went to the dressing room that was very powerful for me.

"I can't understand why a manager would take notes during the game. Put your head down to write and you miss a goal?"
