It's been eight years since United lifted the trophy.
"There are quite a lot of lads who haven't won it, despite being here for a while. It's a competition I've watched since I was growing up and I look forward to it.
"I was quite shocked at how long it has been since United won the FA Cup. This club has always been successful. Luckily we have another good draw, at home to Reading, and we need to make it count," said Smalling.
