The last time Fergie's side lifted the trophy was when they beat Millwall in the 2004 final.
Now, after the 4-1 romp over Fulham in the fourth round, Ferguson has admitted just what an important trophy the FA Cup is to win.
Ferguson told Sky Sports News: "It was a good performance. I think we respected Fulham because we played a very strong team today.
"The FA Cup's an important trophy for us this season. We haven't won it for almost 10 years, so we really need to have a big performance this year.
"Rio Ferdinand's never won an FA Cup medal - so we really need to do something about that."
