Ferguson reveals the one demand at Man Utd: WIN!
Ferguson won his 13th Premier League title this week.
"If you are going to manage this club, you have to accept there is a sacrifice you have to make," Ferguson said.
"You need to make a commitment to it. There is also an expectation to live up to.
"You really need to win all the time. It is the only way you can fulfil the expectation and avoid the criticism."
