Manchester United boss Sir Alex Ferguson says victory at Manchester City would be one of the best of his Old Trafford career. Fergie believes it would be a significant moment in his Old Trafford tenure if they were to come out on top.
"If we win [on Sunday] it will be one of our best ever results," Ferguson told MUTV. "They are a really good, powerful team with massive players.
"It won't be easy and if we defend like we did at Reading we'll be in trouble.
"The important thing for us is to take lessons from the mistakes we're making and do something about it. We need to find a solution."
