Manchester United have won the FA Cup a record eleven times but apart from losing appearances in the final in 2005 and 2007, Ferguson hasn't come close to lifting the trophy in nine years.
"We're at home and we have got to take advantage of that. If we get through, we have got another home tie against Fulham so there's a big incentive for the club to make sure we get through."
For all Ferguson's new found enthusiasm for the FA Cup, his biggest concern at Old Trafford will be the form of Wayne Rooney.
"Wayne coming back is good news. He's been training for a week and looking good," he added.
