The 66-year-old said he still has his passion for the game and it burns as strongly as ever despite fulfilling the long-term ambition of winning the European Cup for a second time.
In a Sky Sports interview with Sir David Frost, Ferguson said: "I´ll carry on for no more than three years, maybe two more. I have to respect my wife because she is a not football fan you know, she´s an Alex Ferguson fan. At that point I wouldn´t have an interest in how it was run. No, it would be the manager´s domain."
